请教2提答案的对错
| 请教2提答案 1.(97.5)
  AS ) secretary of transportation from 1975 to 1977, william Coleman worked (to help )the bankrupt railroads in the northeastern United States (solved) their  (financial ) problems. 答案是C,是应该吧ed 去掉.但是好象A也有错呢?我觉得应该加冠词,因为secretary意思是秘书,又是单数. 
 2.(One of the problems ) of United states  agriculture that has persisted (during the )
 1920's until the present day  is the tendency of farm income to lag (behind ) the costs of (production )  答案是B? during 表示在20年代的这段时间不行吗?
 我选D,production 前面应该加冠词吧?
 
 因为本人的题目是在小摊上买的,不知道做过同样题目的XDJM是否知道答案的对错呢?谢谢
