She has 12 cups of cider and wants to use all of it, with no leftovers of any ingredient. How many total cups of punch will she make? | Cider is 4 parts, so each part equals 12 ÷ 4 = 3 cups.

deduction | truth-teller and liar | mimo-v2.6-flash | On an island, Mira says, "The baker is a liar." The baker says, "The candlemaker is a liar." The candlemaker says, "Both Mira and the baker are liars." Each resident is either a truth-teller or a liar. What is the candlemaker? | **Reasoning:**
Assume the candlemaker is a truth-teller. Then both Mira and the baker are liars. But if Mira is a liar, her statement "the baker is a liar" is false, meaning the baker is a truth-teller — contradiction.
So the candlemaker must be a liar. Then the baker's statement ("the candlemaker is a liar") is true... | candlemaker is a liar | true | [

Marc is not next to Lena. What is the seating order from left to right? | Positions 1–4, left to right. Lena is at position 4 (far right). Marc can't be next to Lena, so Marc isn't at position 3 — Marc must be at position 1. Priya is directly left of Tom, so they fill positions 2 and 3 in that order: Priya at 2, Tom at 3.

The compass is in the box whose number equals the marble's box number minus one. Which box holds the key? | Since Box 3 can't hold the marble, the marble is in Box 1 or 2. If it were Box 1, the compass would need to be in Box 0, which is impossible. So the marble is in Box 2 and the compass is in Box 1.

What is the latest time Pia can start? | Pia's schedule in order: pharmacy (15 min), 5 min travel, post office (15 min), 5 min travel, bakery (15 min).
- Pharmacy can't start before 4:00 pm (opens).

She must pack the towel before the sandals, and the sunscreen immediately after the book. The hat goes first. How many valid orderings are there? | Hat is fixed first, so positions 2–5 hold towel, sandals, book, sunscreen. Book and sunscreen must be a consecutive pair, which can start at position 2, 3, or 4 — 3 placements.

cause-effect | which option would actually work | mimo-v2.6-flash | A greenhouse heater runs only when its sensor reads below 5°C. Last night the sensor was covered by a fallen tarp, blocking airflow, so it read 18°C all night while the true temperature dropped to 1°C. Which single action would have prevented the frost damage: adding a second heater, moving the sensor, or watering the ... | The heater never ran because the covered sensor falsely read 18°C, well above its 5°C cutoff. Adding a second heater would not help if it is tied to the same faulty sensor reading, and watering plants does not reliably prevent frost damage. Moving the sensor restores an accurate reading, so it would have dropped below ... | moving sensor | true | [

everyday-logic | fair sharing of items | mimo-v2.6-flash | Dara and her three cousins split 20 stickers evenly. Two cousins give back one sticker each to Dara. How many stickers does Dara have now? | Dara and her three cousins each get 5 stickers (20 ÷ 4 = 5). Two cousins each give Dara one sticker, so Dara gains 2 stickers. Dara now has 5 + 2 = 7 stickers.

code-trace | off-by-one in a range | mimo-v2.6-flash | Aisha runs this: total = 0; for i in range(1, 8, 2): total += i; then prints total and the number of loop iterations. What does she print? | range(1, 8, 2) produces the values 1, 3, 5, 7, so the loop runs 4 times. total = 1+3+5+7 = 16.

everyday-logic | planning errands in order | mimo-v2.6-flash | Mara needs to drop off dry cleaning (closes 6 pm), buy eggs (store closes 8 pm), and pick up her son (available only after 5:30 pm). She finishes work at 4 pm, and each errand takes 30 minutes including travel. If she must pick up her son last, what is the earliest time she can be done with all three? | Mara finishes work at 4 pm. She can do dry cleaning from 4:00–4:30, eggs from 4:30–5:00, then wait until 5:30 when her son is available, picking him up 5:30–6:00. Since the son must be last and isn't available until 5:30, that pickup takes 30 minutes, ending at 6:00 pm.

cause-effect | predict the result of an action | mimo-v2.6-flash | A warehouse chills fruit at 4°C. Worker Priya accidentally sets one cooler to 14°C overnight, and the mangoes inside are already nearly ripe. Compared with the mangoes in the correctly set cooler, will the mangoes in the warm cooler ripen faster, slower, or at the same rate? | Ripening is driven by enzymes and by the fruit's own ripening processes, which speed up as temperature rises. At 4°C, the mangoes are kept cold enough to slow ripening considerably. At 14°C, those processes run faster, so the mangoes in the warm cooler will ripen more quickly than the ones held at the correct temperatu... | faster | true | [

quantitative | proportions in a recipe | mimo-v2.6-flash | A punch recipe uses 3 parts cranberry juice, 2 parts ginger ale, and 1 part lime cordial. Mira has 300 ml of cranberry juice and wants to use all of it, keeping the proportions exact. What is the total volume of punch she can make, in ml? | Each part equals 300 ÷ 3 = 100 ml. The recipe uses 3 + 2 + 1 = 6 parts total, so 6 × 100 = 600 ml.

code-trace | value of a variable after a loop | mimo-v2.6-flash | Rita starts with x = 6. She repeats these steps four times: first add 3 to x, then if x is now even, divide it by 2. What is the final value of x? | Rita applies the two-step cycle four times starting from x = 6.
Iteration 1: 6 + 3 = 9 (odd, keep 9)
Iteration 2: 9 + 3 = 12 (even, 12/2 = 6)
Iteration 3: 6 + 3 = 9 (odd, keep 9)
Iteration 4: 9 + 3 = 12 (even, 12/2 = 6)
The pattern alternates between 9 and 6, so after four iterations the value returns to 6.
