4.     A work of architecture, if it is to be both inviting and functional for public use, must be unobtrusive, taking second place to the total environment. Modern architects, plagued by egoism, have violated this precept. They have let their strong personalities take over their work, producing buildings that are not functional for public use.

Which one of the statements below follows logically from the statements in the passage?

(A) Unobtrusive architecture is both inviting and functional.

(B) Modern architects who let their strong personalities take over their work produce buildings that are not unobtrusive.

(C) An architect with a strong personality cannot produce buildings that functional well for the public.

(D) A work of architecture that takes second place to the environment functions well for public use.

(E) A work of architecture cannot simultaneously express its architect’s personality and be functional for public use.

一道lsat题，好像也是feifei上的一道题吧。题干不难，正确选项是B,我选的是E

关于B 我的疑问是： 

     题干给出的关系是 both inviting and functional for public use → unobstrutive    即X→Y

      而B选项的关系是let their strong personalities take over their work → produce bulidings not functional for public use →not unobtrusive  即非X→非Y     但原命题正确并不代表否命题正确啊  所以我觉得B有问题

  关于E  如果错的话也就是express its architect's personality 不等同于strong personalities take over their work  不过因为词组意思错而错误的情况比较少  不知道各位牛牛怎么想？
