Explanation: Looking at the image carefully, the handlebars on this Triumph motorcycle are not clearly visible. The angle of the photograph is from the front-side, and while the front forks are clearly visible, the handlebars themselves are largely hidden behind the fuel tank and the angle of the shot. The top portion where handlebars would normally be visible is obscured by the perspective and the large fuel tank dominating the view. The handlebars are essentially not visible in this promotional/studio image.

Answer: 2

Answer: 0


Explanation: Looking at the front of the Amtrak locomotive #146, I can examine the headlight area. The front of the locomotive is clearly visible in the image. However, the headlights on the front of the train are not prominently illuminated or easily distinguishable in this image. The front face of the locomotive is visible, but the headlights themselves are not clearly lit up or standing out. They appear to blend into the front fascia of the locomotive and are not easily discernible as distinct, glowing headlights.

Answer: 1


Explanation: Looking at the Amtrak locomotive #146 in the image, I can see the front of the train clearly. The driver's cab is at the front of the locomotive, and the cab windows are visible on the front face of the engine. The windshield/cab windows of the locomotive are clearly visible at the top front portion of the engine, showing the characteristic angled windscreen design of the Amtrak P42DC locomotive. The windows are clearly discernible in the image.

Answer: 0


Explanation: The crown of the watch (the winding/setting knob on the side of the case) is not clearly visible in this image. The watch is photographed from a top-down perspective, lying flat on a wooden surface. The octagonal case of the Audemars Piguet Royal Oak is visible, but the crown, which would be located on the right side of the case, is largely obscured or hidden from this overhead angle. It is not clearly visible in this shot.

Answer: 2


Explanation: Looking at the Windows 7 desktop image, I can see the taskbar at the bottom of the screen. In Windows 7, the Start button (the Windows orb/pearl) is typically located at the far left of the taskbar. However, in this image, the taskbar is visible but the Start button on the far left of the taskbar is not clearly visible. The taskbar shows icons for Internet Explorer, Windows Explorer, and a media player, but the distinctive Windows 7 Start orb is not visibly present in this screenshot — it appears the leftmost portion of the taskbar may be cut off or the button is absent from view.

Answer: 2


Explanation: Looking at the image, I can see the helicopter's main rotor system at the top of the aircraft. The rotor hub and blades are visible, though the blades extend partially out of frame and are somewhat difficult to make out clearly due to the angle and positioning. The rotor head/hub is visible but the full rotor system is not entirely clear or prominently displayed - it can be seen but requires some effort to distinguish clearly.

Answer: 1


Explanation: Looking at the image, the airplane is photographed from a front/head-on perspective. The cockpit area is at the nose of the aircraft, which is facing directly toward the camera. The nose of the plane is white at the top, and the cockpit windows should be just below the nose dome. However, due to the head-on angle and the dark coloring of the fuselage in that area, combined with the overcast/hazy lighting conditions, the cockpit windows are not clearly distinguishable. There appears to be some dark region where the cockpit windows would be, but they are extremely difficult to make out due to the direct frontal angle, dark fuselage coloring, and lighting conditions.

Answer: 1


Explanation: Looking carefully at the image of this stainless steel wall-mounted drinking fountain, I can see the smooth reflective basin. While drain holes are typically present in drinking fountains, in this image the highly reflective stainless steel surface and the angle/lighting make it very difficult to clearly see any drain hole. There may be one present near the bubbler area, but it is not clearly distinguishable from the reflections and surface texture of the metal.

Answer: 1


Explanation: Looking at the image, the airplane has two engines mounted under its wings. Both engines are clearly visible in the image. The engines are large, prominent features of the aircraft and can be easily identified beneath each wing without any obstruction. They are well-lit and in clear view from this bottom-front angle of the aircraft.

Answer: 0


Explanation: The image shows the underside of a commercial aircraft. Looking carefully at the wings, the engines (jet turbines) are mounted beneath the wings. However, from this directly-below perspective, the engine nacelles are visible but they appear quite dark and blend into the underside of the wing structure, making them hard to clearly distinguish. They are present but not clearly visible.

Answer: 1


Explanation: The vertical stabilizer (tail fin) of the United Airlines aircraft is visible in the image. Looking at the tail section of the plane, the vertical stabilizer can be seen, though due to the angle of the aircraft (which is photographed from a side/slightly below perspective while on approach), it is somewhat visible but the angle makes it a bit harder to clearly distinguish compared to if the plane were viewed from directly behind or in front. The aircraft's tail is partially obscured by the viewing angle, making the vertical stabilizer visible but not completely clear.

Answer: 1


Explanation: Looking at the image, I can see a white plastic lid on a to-go coffee cup. There is a sip hole/drinking opening visible on the lid, and it appears to have some coffee residue around it. The sip hole is clearly visible in the image - it's the elongated oval opening in the lid, and the coffee drips/stains around it make it even more apparent.

Answer: 0


Explanation: Looking at the image carefully, I can see the top of the backpack. There appears to be a small handle at the very top of the backpack, but it is partially obscured by the angle of the photograph and the positioning of the bag against the chair back. It can be seen but is not entirely clear and distinct - it blends somewhat with the surrounding dark material of the bag.

Answer: 1


Explanation: Looking at the image of this red Alfa Romeo 4C sports car driving on a road, I can examine whether side view mirrors are visible. The car is photographed from a front three-quarter angle. On the driver's side (left side from our perspective), there appears to be a small side mirror mounted on the door/A-pillar area. However, given the angle, speed blur, and the compact design of the Alfa Romeo 4C's mirrors, the mirror is present but not immediately obvious or clearly defined. It can be seen but requires some effort to identify clearly.

Answer: 1


Explanation: Looking at the image, the white plastic lid on the coffee cup does not appear to have a sip hole that is open or visible. The lid appears to be a dome-style lid without a visible drinking hole or siphole cut into it. The lid looks completely sealed/closed with no opening for sipping.

Answer: 2


Explanation: The image shows a gray door with a sign on it. On the right side of the door, there is a door handle/latch mechanism visible. It appears to be a modern electronic or lever-style handle mounted on the door's edge. The handle is clearly visible and identifiable in the image, though it is somewhat narrow and sleek in design.

Answer: 0


Explanation: Looking at the image carefully, I can see a door with blue framing and silver/chrome lever door handles on both sides. The latch mechanism is visible where the handles connect to the door edge. However, the actual latch bolt (the small protruding triangular bolt that engages the strike plate) is not clearly visible. The door appears to be partially open, and while the handle hardware is visible, the latch bolt itself is difficult to distinguish clearly in this image.

Answer: 1


Explanation: The image shows a stainless steel water fountain/bubbler (also known as a drinking fountain) that is very clearly visible in the center of the image. It is an Elkay EZH2O model with a bottle filling station on top and a traditional drinking basin below. The entire unit is prominently displayed and easy to identify.

Answer: 0


Explanation: Looking at the image, I can see a white Apple power adapter/charger sitting on a wooden surface. On the right side of the adapter, there appears to be a USB plug/prong sticking out (the metal prongs used to plug into a wall outlet). However, looking more carefully, I can see what appears to be a small USB port or connector on the right side of the device, but it is quite small and partially obscured. The metal prong visible on the upper right appears to be the wall plug prong, not a USB port. A USB port on this type of Apple charger would typically be on the face/side of the device. It's not clearly visible in this image.

Answer: 2


Explanation: The image shows what appears to be an AirPods charging case being held by a hand on a wooden surface. The viewing angle shows the top and side of the case. The charging port (Lightning or USB-C) is typically located on the bottom of the case. In this image, the bottom of the case is not visible due to the angle and the way the hand is holding it. Therefore, the charging port is not visible in this image.

Answer: 2


Explanation: Looking at the image of this water fountain/drinking fountain, I need to identify if there is a drain visible. In a typical drinking fountain, the drain is usually located at the bottom of the basin. Looking at the stainless steel basin, I can see the basin surface but the drain is not clearly apparent. There appears to be a small hole or opening at the back of the basin where water would drain, but it's not prominently visible. The basin appears scratched and worn, making it harder to distinguish specific features. The drain, if present, would be subtle and not immediately obvious in this image.

Answer: 1


Explanation: The image shows a PlayStation 4 (DualShock 4) controller placed on a blue background. Looking at the controller, there are two analog joysticks (thumbsticks) clearly visible - one on the lower left side and one on the lower right side of the controller's face. They are the two circular protruding thumbstick components that are prominently displayed in the image with no obstructions.

Answer: 0


Explanation: The image shows a hand holding what appears to be an Apple AirPods charging case. The case is being held horizontally, and only the front/side of the case is visible. The charging port (Lightning or USB-C) would typically be located on the bottom of the AirPods case. In this image, the bottom of the case is obscured by the hand holding it, and the orientation does not reveal the bottom edge where the charging port would be found. Therefore, the charging port is not visible in this image.

Answer: 2


Explanation: Looking carefully at the back of the tablet in the image, I can see the silver/gray back panel with some dots near the bottom. There is no Apple logo visible anywhere on the back of the device. The logo is either on the other side, obscured, or absent entirely from this view.

Answer: 2


Explanation: Looking at the image carefully, there is a camera module visible on the back of the Apple iPad. The camera is located in the upper left area of the device, encased in a clear transparent case with a cutout for the camera. The single camera lens/sensor is visible as a small dark circle within the oval-shaped camera bump housing. It is clearly visible in the image, not obscured or hidden.

Answer: 0


Explanation: Looking at the image carefully, I can see the back of an Apple iPad with a mint/sage green case. The smart connector pins are typically located on the bottom or side edge of the iPad. In this image, the bottom edge is partially visible, but the smart connector pins are not visible - they appear to be hidden by the case or not in frame. The image shows mainly the back of the device with the Apple logo, and the green case with a hand strap. No smart connector pins can be identified in this image.

Answer: 2


Explanation: Looking at the image, I can see the back of a silver iPhone placed face-down on a white surface. While iPhones do have a rear camera, in this particular image the camera module at the top of the phone's back is not clearly distinguishable or visible. The angle and lighting make it difficult to make out the camera lens clearly. The back of the phone mostly shows the Apple logo and 'iPhone' text, with the camera area not being prominently visible or identifiable.

Answer: 2


Explanation: Looking at the iPad's lock screen carefully, I can see the time displayed as 22:05 prominently. Checking the screen for battery percentage - on iPads with Face ID (no home button), the battery indicator typically appears in the top-right corner. However, in this image, the top corners of the screen are not clearly showing a battery percentage number. The lock screen primarily shows the time and 'Swipe up to unlock'. No battery percentage text is clearly visible in the image.

Answer: 2


Explanation: Looking at the image carefully, I can see the bottom edge of an iPhone. There are small dots/holes visible on the bottom edge next to the Lightning connector port, which represent the speaker grille. These speaker holes are present but they are very small and not prominently visible - they require careful inspection to identify. The overall focus of the image shows the home button and Lightning port more clearly, while the speaker grilles are tiny and hard to distinguish clearly.

Answer: 1


Explanation: Looking at the keyboard in the image, the space bar is the long wide key typically found at the bottom center of a keyboard. In this image, the keyboard is photographed from above/top-down view but oriented vertically (rotated 90 degrees). The space bar should appear as a long horizontal bar. Looking at the keyboard carefully, I can see a wider key that appears to be the space bar, but given the rotation of the keyboard and the dark uniform coloring, it is visible but somewhat hard to see clearly.

Answer: 1


Explanation: Looking at the image of the MacBook laptop, the touchpad (trackpad) is located below the keyboard. In this image, the trackpad area is visible but it blends in with the dark gray body of the MacBook, making it somewhat difficult to distinguish clearly. The keyboard is prominently visible, and the trackpad area below it can be seen, but due to the dark uniform color of the laptop body and the angle of the photo, it's not immediately obvious or clearly defined.

Answer: 1


Explanation: Looking at the image, I can see the bottom of a MacBook Pro laptop placed face-down on a wooden table. The laptop appears to be in Space Gray color. Examining the edges and corners of the laptop, I cannot clearly make out rubber feet on the bottom surface. The laptop is lying flat on the table, and the rubber feet (which are typically small rubber pads at the corners) are not visible in this image — they would be on the underside touching the table and thus not visible from this angle.

Answer: 2


Explanation: Looking at the front of the train in the image, I can see the locomotive's front face clearly. The train has cab windows and color markings visible, but examining the front carefully for a headlight, there does not appear to be a clearly visible illuminated or prominent headlight on the front of the locomotive. The image shows the cab windows, 'ĐỔI MỚI' text, and number plate 'D19E-936', but no distinct headlight lamp is apparent.

Answer: 2


Explanation: Looking at the MacBook keyboard in the image, the laptop is rotated sideways. Arrow keys on a MacBook are typically in the bottom-right corner of the keyboard. In this rotated view, I can see the keyboard layout but the arrow keys area (which would be near the bottom-right in normal orientation) is somewhat visible but difficult to clearly make out due to the angle of the photo, the rotation of the laptop, and the worn/dirty state of the keyboard. The arrow keys appear to be present but hard to distinguish clearly.

Answer: 1


Explanation: Looking at the image, the motorcycle is photographed from the rear. At the top of the motorcycle, behind the fuel tank, the handlebars are partially visible. They appear as small protrusions on either side of the instrument cluster/gauges area. They are present but not prominently visible since we're viewing the bike from behind - they are partially obscured and small in the frame, making them difficult to see clearly.

Answer: 1


Explanation: Looking at the image of the black wired computer mouse, I can see there is a scroll wheel area indicated by an oval/elongated slot shape near the top center of the mouse. However, the scroll wheel itself is not prominently visible - it appears to be recessed or flush with the mouse body, making it difficult to clearly distinguish as a traditional raised scroll wheel. The slot/outline is visible but the wheel itself is hard to make out clearly.

Answer: 1


Explanation: Looking at the front of the Amtrak locomotive (number 78) in the image, I can see the front cab area of the train. The locomotive is approaching the camera head-on. The windshield/driver windows should be at the front of the cab, but given the angle (front-on view), lighting conditions with the headlights glaring, and the distance at which the photo was taken, the driver windows are not clearly distinguishable. The front face of the locomotive is visible but the specific driver window is not clearly visible.

Answer: 2


Explanation: The image shows the bottom edge of a smartphone, specifically focusing on the charging port, headphone jack, and speaker grille. The home button would be located on the front face of the phone below the screen, but due to the angle of the photo which focuses on the bottom edge/corner of the device, the home button is not visible in this image.

Answer: 2


Explanation: Looking carefully at the stainless steel sink in the image, I can see the basin of the sink clearly. The drain hole would typically be at the bottom of the sink basin. Looking at the bottom of the sink, there does not appear to be a clearly visible drain hole. The image is taken from an angle where the bottom of the sink is partially visible, but no distinct drain hole can be identified. The lighting and perspective make it impossible to see a drain hole in this image.

Answer: 2


Explanation: Looking at the electrical outlet in the image, I need to determine if any screws are visible. Standard outlet cover plates typically have a screw in the center to hold the plate to the wall, and outlets themselves may have screws. In this image, the outlet cover plate appears clean and white. I do not see any visible screw on the cover plate — there is no center screw visible on the faceplate, and the mounting screws are not visible either. The outlet label 'C14' is on a sticker at the top. No screws are apparent in this image.

Answer: 2


Explanation: Looking at the image of the electrical outlet, I need to determine if any screws are visible. Standard outlet cover plates typically have a screw in the center to hold the plate to the wall. In this image, the outlet cover plate appears to be a modern screwless design where the cover snaps on without a visible center screw. There is no visible screw on the face plate of this outlet. The detection confidence for a screw is extremely low (0.008), confirming that no screw is visible in the image.

Answer: 2


Explanation: Looking at the electrical outlet in the image, I can see a standard duplex outlet labeled 'C14'. The outlet appears to be a 20-amp receptacle. Examining the slots carefully, I can see the two vertical slots (hot and neutral) on each receptacle, but the ground pin holes (the round/D-shaped hole typically located below the two vertical slots) are not clearly visible in this image. The angle and lighting make it difficult to clearly distinguish a ground hole. The outlet appears to show only the two vertical slots without a clearly visible ground hole, possibly due to the angle of the photo or the outlet type.

Answer: 2


Explanation: Looking at the sink in the image, I can examine it for an overflow hole. An overflow hole is typically located near the top/front of the sink basin, below the rim. In this image, I can see the drain at the bottom of the basin clearly, but looking at the sink carefully, there does not appear to be a visible overflow hole. The sink appears to be a drop-in/self-rimming style basin, and the overflow hole (if present) would typically be on the front interior wall of the basin. In this image, it is not clearly visible - the angle and lighting don't reveal one, and it may be hidden or this particular sink model may not have one prominently visible from this angle.

Answer: 2


Explanation: Looking at the image, the train is on a track. The track (rails) can be seen beneath the train and extending to the left side of the image in the foreground. The rails are visible but somewhat obscured by the train itself and the gravel/ballast surroundings. However, you can clearly make out the tracks in the lower left portion of the image extending away from the camera. The track is clearly visible in the foreground.

Answer: 0


Explanation: Looking at the image, this is a traditional balance scale (托盘天平). It has a horizontal beam with numerical markings/graduations (0-10.5) visible on the central beam, but there is no circular dial present. The scale uses a beam/pointer mechanism to indicate balance rather than a rotary dial. No dial is visible in this image.

Answer: 2


Explanation: Looking at the image of the wheelchair, I can see the front (smaller) caster wheel on the right side of the image. It is clearly visible - the small caster wheel is attached to the front of the wheelchair frame near the footrest area. It appears in clear focus and is distinctly identifiable without any obstruction.

Answer: 0


Explanation: Looking at the image, I can see a balance scale (托盘天平, model 11005). Along the horizontal beam/arm of the scale, there is a ruler or measurement scale with numbered markings (0 through 10.5 visible). This ruler/scale is clearly visible on the beam of the balance scale, used for measurement purposes.

Answer: 0


Explanation: Looking at the fire extinguisher image, there is a pressure gauge (the circular dial) visible near the top of the extinguisher. However, while the gauge itself is visible, the needle inside the gauge is very small and difficult to make out clearly due to the image resolution and angle. The gauge face appears red/dark, and while you can tell there is a needle, it is not clearly distinguishable - making it visible but hard to see.

Answer: 1


Explanation: Looking at the image carefully, I can see the zipper running down the front of the Columbia fleece jacket. There appears to be a zipper pull/tag at the bottom of the zipper, but it is quite small and blends into the black fabric, making it difficult to see clearly. It is visible but hard to make out distinctly against the dark background.

Answer: 1


Explanation: Looking at the violin in the image, I can clearly see both f-holes (the curved openings on either side of the bridge) on the front face of the violin body. They are the characteristic f-shaped sound holes that are a defining feature of violins, and in this image they are clearly and easily visible on both sides of the bridge.

Answer: 0


Explanation: The tuning pegs are clearly visible at the top of the violin (the scroll/pegbox area). You can clearly see the four tuning pegs protruding from the pegbox, shown in the same warm brown/amber color as the rest of the instrument. They are well-lit and easy to identify.

Answer: 0


Explanation: The tuning pegs are clearly visible at the headstock (top) of the guitar. You can see the multiple tuning pegs on both sides of the headstock, with their metallic buttons/knobs clearly distinguishable against the wood. They are well-lit and in sharp focus, making them very easy to identify.

Answer: 0


Explanation: The fingerboard of the violin is clearly visible in the image. It is the dark (ebony) elongated piece that runs from the nut (near the pegbox/scroll) down along the neck toward the body of the violin. It contrasts noticeably against the lighter amber/orange wood of the violin body, making it easy to identify and see.

Answer: 0


Explanation: Looking at the violin in the image, I can clearly see the strings running from the tailpiece, over the bridge, along the fingerboard up to the pegbox. The strings are distinctly visible against the body of the violin, and you can clearly make out multiple strings (4 strings as expected on a violin). They are clearly visible without any obstruction or difficulty.

Answer: 0


Explanation: In the image of the microscope, I can see a circular mirror/reflector at the base of the microscope stage. This is the substage mirror (reflector) used to direct light up through the specimen. It is clearly visible as a round, circular mirror mounted on an adjustable arm at the bottom of the microscope stage. It appears as the circular disc visible at the lower portion of the microscope body.

Answer: 0


Explanation: Looking carefully at the microscope image, I can identify the coarse focus knob on the left side of the microscope arm/body. The coarse focus knob is typically the larger of two knobs used to move the stage up and down for initial focusing. In this image, there appears to be a knob visible on the left side of the microscope body, but given the angle of the photograph (slightly from the side-front), the knob is present but not prominently displayed — it's somewhat visible but not crystal clear due to the perspective and image resolution.

Answer: 1


Explanation: Looking at the microscope image carefully, I need to identify if there is a stage clip visible. The stage (the flat platform where slides are placed) is visible in the image. Stage clips are small metal clips that hold microscope slides in place on the stage. In this image, I can see the stage platform, but the stage clips are not clearly distinguishable. The image shows a basic student microscope, and while the stage is visible, any stage clips present would be small and on top of the stage surface. Looking carefully, I can make out what appears to be a clip on the stage, but it is quite difficult to see clearly due to the angle and image resolution.

Answer: 1


Explanation: The scissors in the image have two finger holes (handles/rings) that are clearly visible. Both the left and right handle rings are prominently displayed in the lower portion of the image, showing the classic circular openings of scissor handles in black color. They are easy to see without any obstruction.

Answer: 0


Explanation: Looking at the microscope image carefully, I can see the body of the microscope with what appears to be focusing knobs on the side. The fine focus knob is typically a smaller, more delicate knob located adjacent to or concentric with the larger coarse focus knob. In this image, while I can see some knobs on the arm of the microscope, the fine focus knob specifically is not clearly distinguishable — it may be present but it is difficult to see clearly due to the angle and image resolution. The knobs visible on the left side of the microscope body suggest there are focusing mechanisms, but isolating the fine focus knob specifically is challenging.

Answer: 1


Explanation: The image shows a comb (梳子 in Chinese). A comb by definition has teeth - the thin tine-like projections used for grooming hair. In this image, the teeth of the comb are clearly and prominently visible on the right side of the comb. They are well-lit, in focus, and easily distinguishable as individual tines/teeth of the comb.

Answer: 0


Explanation: In the image, the objective lenses (the turret/nosepiece with multiple objective lenses) are clearly visible on the right side of the microscope body. The revolving nosepiece with what appears to be multiple objective lenses of different magnifications can be distinctly seen attached to the body tube of the microscope. They are well-lit and clearly distinguishable in the image.

Answer: 0


Explanation: The image shows a mug from a slightly elevated angle. The top edge (rim) of the mug is clearly visible — you can see the circular opening at the top of the mug, showing both the outer edge and the inner wall of the cup. The rim is well-lit and easy to distinguish against the background.

Answer: 0


Explanation: Looking at the image of the spectacles, I can see the temple arms (the side pieces that extend back to rest on the ears). The glasses are folded, so the temple arms are folded inward/downward. I can see at least one temple arm clearly — the black temple arm tips are visible on both sides of the folded glasses. They are clearly visible in the image.

Answer: 0


Explanation: The clock in the image clearly shows multiple hands - there is a minute hand, an hour hand (both dark/blue colored), and a red second hand. All hands are clearly visible against the white clock face with good contrast. The hands are easily distinguishable and point to approximately 8:25 with the second hand near 3.

Answer: 0


Explanation: The image shows two power strip extension boards (插线板). Both have clearly visible white power cords attached to them. The left one shows the cord running from the strip to a plug, and the right one shows the cord coiled up near the bottom. The cords are white against a white background but are clearly distinguishable and easy to see.

Answer: 0


Explanation: Looking carefully at the image of the folded spectacles, I can see the nose bridge area between the two lenses. There appears to be a small nose pad component near the bridge area, but given the folded position of the glasses and the angle of the shot, it is present but somewhat difficult to clearly see. The glasses are folded and positioned at an angle, making the nose pad area partially obscured but still somewhat discernible.

Answer: 1


Explanation: The alarm clock in the image has clearly visible dial numbers 1 through 12 printed in bold dark blue/black numerals on a white clock face. They are large, high contrast, and completely unobstructed, making them very easy to read.
