题目如下：

1. Editorial: This y ear, the Marionville school board received five textbook proposals
submitted by local book publishers. In each instance, the school rejected the
proposal on the grounds that the curriculum covered within the textbooks was
inadequate, controversial or, surprisingly , too comprehensive. Consequently ,
because the school board must accept at least one textbook proposal in order to
have materials for this upcoming y ear, the school board has acted negligently in
failing to accept at least one of the proposals.
The answer to which one of the following questions would be most useful in
evaluating the truth of the conclusion in the editorial?
(A) How many of the proposals that were rejected by the school board were
rejected on the basis that the curriculum was too comprehensive?
(B) What was the opinion of the parents’ association regarding the five textbook
proposals?
(C) Did any non-local textbook publishers submit a textbook proposal to the
Marionville school board?
(D) Could the school board have accepted multiple proposals that would have, in
combination, have provided the appropriate materials?
(E) In previous y ears, has the Marionville school board rejected all the textbook
proposals submitted by book publishers?

答案是C，我选的D。

D选项错误的描述仅如此：
Answer choice (D): For this answer, again supply “Yes” and “No” responses.
Neither answer changes our view of the argument because we already know that the
school board rejected all five of the proposals. Thus, answer choice (D) is incorrect.

但是D答案不能作为一种对过去的假设么，明明原本这样是可能可行的，但是却被忽略。

这题只在C/D之间犹豫。

C. Did any non-local textbook publishers submit a textbook proposal to the Marionville schoolboard? Apply the Variance Test: YES, they did, so we know that the school board still has choices and might accept at least one proposal (weaken the editorial's conclusion); NO, they didn't, so we know that the school board doesn't have any choice (strengthen the editorial's conclusion). C is correct.

D. Could the school board have accepted multiple proposals that would have provided the appropriate materials?
could have accepted 的意思是可能接受几个proposals，would have provided的意思是这几个proposal都可能provide适当的授课材料。could，would都表明有一定的possibility。
Apply the Variance Test: Yes, it could; No, it could not. 可惜，这个答案不能帮助我们判断editorial的conclusion，因为the reallity tells us that the school board has received 5 proposals and rejected all. In other words, we already know the answer to this question, so asking this question will not help us to make further evaluation.

可以作为对过去的假设，但是回答这个问题对于evaluate the argument没有帮助，因为我们已经知道结果了。我们更想知道的是除了这五个proposals，学校还有没有别课本的选择。
