题目来源是magoosh
By the late 1960s, the rising number of American casualties in Vietnam and the 1968 Tet Offensive, the Viet Cong's coordinated surprise attack on American installations throughout the whole of Vietnam, suggested that Vietnam was an ultimately unwinnable situation for the United States.
A suggested that Vietnam was an ultimately unwinnable situation for the United States
B suggested Vietnam to be an ultimate unwinnable situation to the United States
C had suggested that Vietnam was an ultimately unwinnable situation to the United States
D suggesting Vietnam to be an ultimately unwinnable situation to the United States
E suggesting that Vietnam was an ultimate unwinnable situation for the United States

OA:A. 我选了C

这里出现了by the late 1960s，后面的谓语suggest不是应该用过去完成时吗，表示过去的过去。我的理解是：在1960s之前，美国伤亡情况就表明他们并没有赢。（感觉这个suggest暗含在1960s之前就一直有这个迹象表明，所以感觉应该是过去的过去啊）

官网的解释，但俺觉得还是不清楚

Text Explanation
Split #1a: forms of the verb "suggest".  The main subject of this sentence is compound, joined by "and" --- "the rising number ….. and the Tet Offensive".  Everything between the commas is a modifying phrase modifying the "Tet Offensive."  Then, we get to "suggested"/ "had suggested"/ "suggesting", and everything after this is a "that" clause, the object of the verb "suggest."  This sentence needs a verb.  The forms "suggested" & "had suggested" are genuine verbs --- these would serve as the main verb of the sentence.  The word "suggesting" is a participle, and if a participle appears at this place in the sentence, the sentence overall would have no verb.  Choices (D) & (E) make this mistake: they commit the "missing verb" mistake.

Split #1b: which form of the verb should we use?  The form "suggested" is simple past tense, perfectly appropriate here.  The form "had suggested" is past perfect.  We use the past perfect tense if we want to communicate that this verb, this action, took place before some other past action.  Here, the "suggesting" had to happen after the Tet Offensive, so the past perfect is completely incorrect.  Choice (C) makes this mistake.

Split #2: the idiom with "suggest".  The verb "suggest" requires a "that" clause.  The structure "suggested that Vietnam was …" is completely correct, and the structure "suggested Vietnam to be …" is completely incorrect.  Choices (B) & (D) make this mistake.

Choice (A)
is the only possible answer.

Frequently Asked Questions

FAQ: I still think it would be correct to use the past perfect "had suggested" (answer choice C). Why can't we do this?

A: We can only use the past perfect when there is another separate event in the sentence. The past perfect tense, "had," is used when we want to communicate that this verb, this action, took place before some other past action.

Here, the Viet Cong's coordinated surprise attack happened by the late 1960's, so we're not dealing with two clearly separate events. Also, note that the "suggesting" did not take place before the Tet Offensive. Therefore, it would be incorrect to say "had suggested."

同时，我又的确觉得had suggested 在这里读起来又那么奇怪

我去gmatclub看到大家争论不休，很多专业也参与其中。比较肯定的部分是suggested ...这里用完成时不合逻辑。完成时是必须发生前参考点之前的，而这个时间点是by the Late 1960s ... suggest 不可能发生在这之前。。用一般过去时就可

争议的地方就是by the late of...很多人说应该改成in the late

个人觉得没必要纠结了何况这题在idiom用法是c也是明显错误
掌握做题方法比什么都重要
祝你考试取高分

By the late 1960s, the rising number of American casualties in Vietnam这是一个事件，the 1968 Tet Offensive, the Viet Cong's coordinated surprise attack on American installations throughout the whole of Vietnam这又是一个事件，两个发生在过去的事件suggested that Vietnam was an ultimately unwinnable situation for the United States.所以用过去式
