You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
You are given a sentence, a question and two answer options. Your task is to write down the index ('A' or 'B') of the **incorrect** option for the given question.

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: B
Why? Typically, people with thin frail legs squat less weight than people with big strong legs, so the incorrect answer is Benny.

(A) the wooden gym floor (B) the concrete
