177. So poorly educated and trained are many young recruits to the United States work force that many business
executives fear this country will lose its economic preeminence.
(A) So poorly educated and trained are many young recruits to the United States work force that
(B) As poorly educated and trained as many young recruits to the United States work force are,
(C) Because of many young recruits to the United States work force who are so poorly educated and trained,
(D) That many young recruits to the United States work force are so poorly educated and trained is why
(E) Many young recruits to the United States work force who are so poorly educated and trained explains why

In B, the subject of the as ... as clause (young recruits) should be the subject of the main clause as well (e.g., they). Furthermore, main clauses following concessive clauses must express a contrasting notion: for example, "As ill-prepared as they are, they nevertheless find good jobs." C offers a wordy, convoluted because clause.

1，og说有让步状从有对比的意思，所以B中光有as...as了，主句却没有nevertheless等转折的意思，对吗？

2，C中的because of 怎么就wordy了？

3，E中.........explains why除了主谓一致的问题外，是否why应该改为that？

B- y are right, this answer did not give the contrast meaning which

was required by this pasage

C- confusion, "who" clause is far away from the subject it means to

modify

E-Change to "that" does not solve the problem, think the whole

sentence as:

Many young recruits .... explains why (that)

many thanks!!!
