everyday-logic | planning errands in order | mimo-v2.6-flash | Mara must drop her dry cleaning (closes at 5), pick up her dog from the groomer (closes at 6), and buy milk before the store closes at 4. She finishes work at 3 and needs 15 minutes for each stop, starting from home. What order should she do the stops? | Milk first, then dry cleaning, then the groomer. She starts at 3:00, so she gets milk by 3:15 (before the 4:00 close), drops dry cleaning by 3:30 (before 5:00), and picks up her dog by 3:45 (before 6:00). Doing milk last risks missing the 4:00 close, and the groomer closes last so it can go last.

What time does it arrive back at Millhaven? | Outbound trip: 2:45 PM + 55 minutes = 3:40 PM arrival at Amble Island. Wait: 3:40 PM + 30 minutes = 4:10 PM departure. Return trip: 55 + 5 = 60 minutes, so 4:10 PM + 60 minutes = 5:10 PM.
Final answer: 5:10 PM | 5:10pm | true | [
"5:10pm",
"5:10pm"

quantitative | proportions in a recipe | mimo-v2.6-flash | A punch recipe uses 3 parts pineapple juice, 2 parts orange juice, and 1 part ginger ale. Marco has 500 ml of pineapple juice but wants to use it all while keeping the ratios exact. How many milliliters of ginger ale does he need? | Marco has 500 ml of pineapple juice, which represents 3 parts of the recipe.
Each part = 500 ÷ 3 = 500/3 ml.
Ginger ale requires 1 part, so he needs **500/3 ml ≈ 166.67 ml** of ginger ale.
Final answer: 500/3 ml (approximately 166.67 ml) | 500/3 ml 166.67 ml | true | [

deduction | elimination from hints | mimo-v2.6-flash | Mara's key is in one of four pockets: left jacket, right jacket, left pants, right pants. Clues: it is not in any jacket pocket; it is not in the left pants pocket. Where is the key? | The key is not in either jacket pocket, and not in the left pants pocket. The only remaining option is the right pants pocket.
Final answer: right pants pocket | right pants pocket | true | [

code-trace | boolean logic in a condition | mimo-v2.6-flash | Rita's code checks: if (x > 4 AND y < 10) OR (z == 2). She runs it with x = 3, y = 5, z = 2. Does the condition evaluate to true or false? | x > 4 is false (3 is not greater than 4), and y < 10 is true (5 is less than 10), so the first part (false AND true) is false. z == 2 is true. Since false OR true is true, the whole condition evaluates to true.
Final answer: true | true | true | [

cause-effect | simple biology or weather reasoning | mimo-v2.6-flash | A cold front moves into a town where the air is warm and humid. By afternoon, thick clouds form and a heavy rainstorm begins. What caused the rainstorm? | A cold front moved into warm, humid air. The cold air pushed the warm, moist air upward. As it rose, it cooled and the water vapor condensed into thick clouds. This produced heavy rain.
Final answer: The cold front lifted warm, humid air upward, causing it to cool, condense into clouds, and fall as heavy rain. | cold front lifted warm, humid air upward, causing it to cool, condense into clouds, and fall as heavy rain | true | [
"cold front forced warm, humid air upward, where it cooled and condensed into rain-producing clouds",
"cold front lifted warm, humid air upward, causing it to cool, condense into clouds, and fall as heavy rain"

everyday-logic | choosing between routes | mimo-v2.6-flash | Marta can reach the ferry via the coastal road, which takes 25 minutes but adds a 5-minute parking walk, or the tunnel, which takes 18 minutes plus a 10-minute walk. The ferry boards at 3:40 and she leaves at 3:20. Which route lets her arrive earliest? | Coastal route: 25 + 5 = 30 minutes, arriving 3:50. Tunnel: 18 + 10 = 28 minutes, arriving 3:48. The tunnel gets her there 2 minutes earlier, though both arrive after the 3:40 boarding time.
Final answer: the tunnel | tunnel | true | [
"tunnel",
"tunnel arrives 3:48, though she misses 3:40 boarding either way"

everyday-logic | seating people | mimo-v2.6-flash | Five friends sit in a row of five chairs. Priya refuses to sit at either end. Marco must sit directly to Priya's left. The other three (Lea, Tom, Ravi) fill the remaining seats. How many distinct arrangements of all five people are possible? | Priya can occupy positions 2, 3, or 4 (not the ends). Marco must be immediately left, so he takes position 1, 2, or 3 respectively — all valid. That gives 3 valid placements for the Priya–Marco pair. The remaining three people (Lea, Tom, Ravi) can be arranged in the three leftover seats in 3! = 6 ways. Total: 3 × 6 = 1... | 18 | true | [

cause-effect | predict the result of an action | mimo-v2.6-flash | A baker raises her oven temperature from 180°C to 220°C but bakes her bread for the same 40 minutes. What will most likely happen to the crust? | The crust will likely become much darker, thicker, and harder — possibly burnt or bitter — because the higher temperature causes faster browning (Maillard reaction and caramelization) over the same 40 minutes, while the interior may dry out more.
Final answer: The crust will become darker, thicker, and likely burnt or... | crust will become darker, thicker, and likely burnt or overly hard | true | [
"crust will become darker, thicker, and likely burnt or overly hard",
"crust will likely become much darker, harder, and possibly burnt"

code-trace | boolean logic in a condition | mimo-v2.6-flash | Maya runs this code:
x = 7; y = 3; flag = False
if not flag and (x % 2 == 1 or y > 10): print("A")
else: print("B")
What is printed? | flag is False, so not flag is True. x % 2 == 1 is True since 7 is odd, so the or condition is True regardless of y. True and True is True, so the if branch runs.
Final answer: A | a | true | [

everyday-logic | timing a sequence of chores | mimo-v2.6-flash | Nia starts watering plants at 2:15 and it takes 8 minutes. Folding laundry takes 12 minutes and must finish by 2:40. She does the tasks back to back. If she starts watering exactly at 2:15, what time does she finish folding? | Watering runs 2:15 to 2:23. Folding starts right after, so 2:23 plus 12 minutes is 2:35, which is before the 2:40 deadline.
Final answer: 2:35 | 2:35 | true | [
