问题     Biology may not be destiny, but genes apparently have a far greater influence on human behavior than is commonly thought. Similarities ranging from phobias to hobbies to bodily gestures are being found in pairs of twins separated at birth.
    Professor Bouchard of the University of Minnesota reports that so far, exhaustive psychological tests and questionnaires have been completed with approximately 50 pairs of identical twins reared apart, 25 pairs of fraternal twins reared apart, and comparison groups of twins reared together. Studies show that twins rend to have similar mannerisms, gestures, speed and tempo in talking, habits and jokes.
    Many of the twins dressed in similar fashion. One pair had practically the same items in the toilet cases, including the same brand of cologne and a Swedish brand of toothpaste.
    Twins also tend to have similar hobbies and interests—a male pair had similar workshops in their basements and a female pair had strikingly similar kitchen arrangements.
    Bouchard doesn’t have enough information on abnormal behavior or psychopathology to make generalizations, but he has found repeated similarities. One pair of women were both very superstitious; another pair would burst into tears at the drop of a hat, and questioning revealed that both had done so since childhood.
    Overall the emerging findings of the study constitute a powerful rebuttal to those who maintain that environmental influences are primary shaping forces of personality. The textbooks are going to have to be rewritten, Bouchard predicts.
According to the passage, twins tend to have similar behavior______.
选项 A、because they share the same experiences
B、because they have the same parents
C、if they are not reared together
D、no matter whether they are reared together or not
答案D
解析 细节题。通过similar behavior回到原文定位到第一段最后一句，可知50对双胞胎，无论何种方式抚养，他们常常都有相似的行为举止。因此本题正确答案为D。
