请问OG-25题

wendywheel

25. It can be inferred from the passage that the morphogenetic determinants present in the early embryo are

(a) located in the nucleus of the embryo cells

(b) evenly distributed unless the embryo is not developing normally

(c) inactive until the embryo cells become irreversibly committed to their final function

(d) identical to those that were already present in the unfertilized egg

(e) present in larger quantities than is necessary for the development of a single individual

I don't know why D is incorrect.  Refering back to the article, it says 'biologist Paul Gross found that an unfertilized egg contains substances that function as morphogenetic determinants.'  是不是我对identical这个单词的理解错误？谢谢大牛们的指教！还想请问一下，这种经常带有'infer'于题中的题，应该是information体型而需要依照对文章的记忆作答，还是属于细节题，应尽量原文定位？再次感谢NN们！
