The question is basically asking what Q response rules out with regards to what M is trying to imply.

Great question. This is a tricky one.

Let's look at the argument:

M: It is almost impossible to find a person ages 85-90 who are primarily left-handed.

Now, we might be thinking why is M saying this? Is M using this fact to say that right-handed people live longer?

Q: Seventy to ninety years ago, however, children were punished for using their left hands.

Q responds by saying this fact is easy to explain because people in this age group were forced to use their right hand regardless of whether they were born right or left-handed.

The question stem asks us what is the purpose of Q's response? or what Cannot Be True given Q's response - as @zacahry aptly put it?

(A) is the correct answer choice because it points out that Q offers evidence to dispute M's hypothesis that being born right-handed confers a survival advantage.

Does this make sense?
Let me know if you have any other questions.
