15. 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 published 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.
答案是A
我承认A是M的假设,但提问意思是说Q用来反对M的解释基于下面哪个假设,把这句话概括就是“解释基于哪个假设?”,最后怎么就变成了M的前提假设了哪?不太明白,请大虾指点迷津,谢谢 |
