M: It is almost impossible to find a person between the ages of 85 an 90 who primarily uses the left hand.
Q: Seventy to ninety years ago, however, children were punished for using their left hands to eat or to write and were forced to use their right hands.
Q’s response serves to counter any use by M of the evidence about 85 to 90 year olds in supports of which one of the following hypotheses?
(A) Being born right-handed confers a survival advantage.
(B) Societal attitudes toward handedness differ at different times.
(C) Forcing a person to switch from a preferred hand is harmless.
(D) Handedness is a product of both genetic predisposition and social pressures.
(E) Physical habits learned in school often persist in old age.

A
If M were to say this - A, then Q's response is sufficient to counter the question. "People who were using left hand (or born left h.) also survived -only that they now use their right-hand"
