Identicaltwins tend to have similar personalities; if environment outweighs heredity inpersonality development, twins raised together should presumably have moresimilar personalities than those raised apart. A recent study of identicaltwins in both situations measured 11 key traits through a questionnaire, andconcluded that 7 of the 11 are primarily products of heredity. Whichof the following, if established, would cast the most doubt on the study’sresults? (A)Fewer than half of the pairs of twins studied were raised separately.
(B)The ages of all of the twins studied fell within a 10-year range. (C)Some of the traits that the study attributed to heredity developed in theseparately raised twins because those pairs all grew up in similar families. (D)Although over half the traits measured were determined to be linked toheredity, the nature of those traits varied widely.（C） (E)The 11 traits that were measured constitute a representative sample of larger,generally accepted pool of key personality traits 这道题A为什么不对？
不过C选项的这个因果关系很诡异 Some of the traits that the study attributed to heredity developed in theseparately raised twins because those pairs all grew up in similar families. 因为分养的双胞胎被在类似的家庭抚养，所以他们具有一些被算作遗传决定的特征？
