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. [br] It can be inferred from the passage that______.
选项 A、twins have many similarities because they inherited them from their parents
B、twins tend to be more superstitious than other people
C、twins reared apart tend to have similar mannerisms because they have the same education
D、twins have many similarities because of the genes they inherit from their parents
答案 D
解析 推理题。文章首句就告知我们基因对行为的影响可不是一般地深远。全文用了双胞胎无论何种抚养方式，都趋向有相同的行为举止来证明具有相同基因是这种现象的深层原因。因此本题正确答案为D。
