You are given a sentence, a question and two answer options ('A' and 'B'). Your task is to find the **incorrect** answer (return the string of the incorrect option, not A/B).
One example: Sentence: Jacob and Benny are squatting at the gym. Jacob has thin frail legs and Benny has big strong legs. Question: Who squats less weight? (A) Jacob (B) Benny
Solution is here: Benny
Explanation: Typically, people with thin frail legs squat less weight than people with big strong legs, so the incorrect answer is Benny.

Now, solve this: Sentence: A weighty cement mixer and a light motorcycle are waiting at a red light. Question: When the light turns green, which accelerates more slowly? (A) cement mixer (B) motorcycle
Solution:
