1 contend that... 故a or b b的which不对所以只能a

contend to be d选项念起来太累赘了觉得没有a顺。。。

不知道有没有高人知道contend to be在gmat里边算对不

1. According to Manhattan SC Guide 2009, the correct usage is “contend that”.
Below are the examples given in the SC guide
Correct: They contend that they can decipher the code.
Wrong: They contend they can decipher the code.
They contend the code to be decipherable.
They contend the ability to decipher the code.
Personally, I felt that the meaning of “can be traced” and “traceable” are not exactly the same. In this sentence, “can be traced” means that the linguists can trace back the origin of thousands of spoken language, and the focus is that linguist can do it. “Traceable” means capable of being traced, and the focus changes to that the language has the capability of being traced.

2. This question is from OG Verbal Guide. Here are the explanations given in the book.
B. The construction “y will happen unless x happens first” requires the present tense following the “unless” clause, rather than the future tense.
E. “Lacking” illogically and incorrectly modifies damage.
3. Answer D is the best because it shows the contrast relationship here. “The cells beat in unison” is the common characteristic among the cells, while “adopt specialized orientation” shows the differences of difference cells. Here using “yet” can clearly show the relationship here. Furthermore, the parallel structure here should be applied to “beating” and “adopting orientation” only, but not applied to the 3 verbs. When we talk about parallelism in GMAT, we need to consider both logically and structurally parallel. Logically parallel means the meaning must be also be parallel for the different verbs.

4. B: the correct idiom should be “likely to do sth”, and we could say that “someone is at disadvantage”, but cannot say “someone is disadvantaged”.
C: “liable” changes the meaning of the original sentence.

5. Personally, I felt that A is also grammatically correct. But I think C could better express the meaning of the sentence.

6. Although “there be” is not preferred, you still need to look into the whole sentence. And if it is the only grammatically correct sentence, we still need to choose it.
E: The structure is not parallel before and after “as many as”. After “as many as”, sth like “he had” or “she had” should be added. I have a question here. Which pronoun should be used to refer to “every 32 pupils”? Anyone has any idea?
