下記の問題もよろしくお願いします。
Identical twins tend to have similar personalities; if environment outweighs heredity in personality development, twins raised together should presumably have more similar personalities than those raised apart. A recent study of identical twins in both situations measured 11 key traits through a questionnaire and concluded that 7 of the 11 are primarily products of heredity.
Which of the following, if established, would cast the most doubt on the study's results?
(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 the separately raised twins because those pairs all grew up in similar families.
(D) Although over half the traits measured were determined to be linked to heredity, the nature of those traits varied widely
(E) The 11 traits that were measured constitute a representative samle of a larger, generally accepted pool of key personality traits.
正解はＣ。
本文および選択肢Ｃの解釈が十分でないためと思いますが、Ｃが正解となる理由がよく分かりません。
この設問は、weakenだと思いますが、
結論：11の質問のうち、7つが遺伝子に起因する
に対して、暗に言おうとしていることは、
「similar peronality はすべて環境に起因する」ということなのでしょうか？
