A.they assigned to do
B.to be assigned doing
C.that was being assigned doing
D.assigned for doing
E.it assigned to do
为什么选E呢，结构是什么？我选的D, assigned for doing 应该是错误的，可是其他选项觉的更不对。

E为正确答案：
assign的用法包括：assign sth.；assign sb. sth.；assign sth. to sb.
assign sb. to sth.；assign sb. to do sth.
并没有assign for doing，

chairperson of...of...+修饰成分，修饰的是chairperson
it指代的是the white house, 这是个定语从句，因为所修饰的内容在从句中作宾语，that省略：The W named R chairperson (that) it assigned to do...
