19.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. 普遍观点认为双胞胎具有相似的性格,如果环境因素影响力超过遗传因素的话,那么在一起长大的双胞胎应当比分开来成长的具有更多相似性。 而研究表明两种情况下成长的双胞胎,大部分还是显示出了遗传因素的影响。
Which of the following, if established, would cast the most doubt on the study’s results? weaken研究结果,则反驳遗传作用大。
(A) Fewer than half of the pairs of twins studied were raised separately. 在一起成长的双胞胎比例大,区分不出来是环境还是遗传。
(B) The ages of all of the twins studied fell within a 10-year range. 年龄,无关
(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. 环境虽然不同但是相似,由此性格上的相似性不能归咎于遗传。
(D) Although over half the traits measured were determined to be linked to heredity, the nature of those traits varied widely. traits的nature,无关
(E) The 11 traits that were measured constitute a representative sample of larger, generally accepted pool of key personality traits. traits的选取,无关。
A和C比较难区分,比较一下还是C稍稍胜出一点。 |
