Marta wants to swim laps on a Wednesday evening. Which conclusion is certain? A) She can swim laps any time Wednesday. B) She cannot swim laps Wednesday evening. C) The pool is closed Wednesdays.

What is the value of d["a"] + d["b"] + d["c"]? | Starting with d = {"a": 1}. The update sets "b" to 2 and overwrites "a" to 5. setdefault("c", 3) adds "c": 3 since "c" isn't present. Then d["b"] = 9 overwrites "b". So d = {"a": 5, "b": 9, "c": 3}, and 5 + 9 + 3 = 17.

Flour now costs 20% more (1.2×), but only 80% as much is used, so flour cost becomes 0.4C × 1.2 × 0.8 = 0.384C. Non-flour costs stay at 0.6C.

code-trace | dictionary update result | mimo-v2.6-flash | Mira runs this Python: d = {"a": 1, "b": 2}; d.update({"b": 5, "c": 7}); d["a"] += d["c"] - d["b"]. What is the final value of d["a"]? | Start with d = {"a": 1, "b": 2}. The update sets b to 5 and adds c = 7. Then d["a"] += d["c"] - d["b"], which is 7 - 5 = 2, so 1 + 2 = 3.

code-trace | dictionary update result | mimo-v2.6-flash | Mira starts with scores = {"ana": 4, "bo": 7}. She runs scores.update({"ana": 6, "cy": 2}) then del scores["bo"]. How many keys does scores have, and what is the value stored under "ana"? | Mira starts with two keys: ana and bo. The update sets ana to 6 and adds cy, giving three keys. Deleting bo leaves two keys: ana and cy. The value under ana is 6.
Final answer: 2 keys, ana = 6 | 2 keys, ana = 6 | true | [
"2 keys, ana = 6",
"2 keys, \"ana\": 6"

quantitative | rates and time | mimo-v2.6-flash | A ferry departs Port Elba for Isola Vela, 90 km away, at 15 km/h. At the same time, a faster ferry leaves Isola Vela for Port Elba at 30 km/h. A gull flying at 45 km/h travels between the two ferries, turning around instantly each time it reaches one. How far does the gull fly before the ferries meet? | The two ferries close the 90 km gap at a combined 45 km/h, so they meet after 90/45 = 2 hours. The gull flies continuously at 45 km/h for those 2 hours, covering 45 × 2 = 90 km.
