- A. Subjunctive Structure-a verb following such verbs as suggest, demand, recommend etc. or nouns as condition, suggestion, recommendation (+ that) is in a base form ( be, do, have, ask, love etc.). Only A follows the rule.
- B. Idiom: model....after , that’s it. However, as you can remember, a sentence correction choice has to be wrong at least for a reason. You’ll see that C, D & E are all
wrong in terms of comparative since they illogically state that the face and the body of the statue look like his mother and his wife (not his mother’s face and his wife’s body) respectively. Read more on our comparative review.
- B. Upon reading the question, you should ask yourself “Who/What is in the orbit of Jupiter?” and “Who/What are using the telescopes?”. If you think (incorrectly that) both are the same, you
can leave the noun in the leading clause. If you think (correctly) that both are different things, you need a noun in the leading clause. The latter results in the sentence like B only. All choices except B suggest that the
astronomers are in the orbit of Jupiter.
- C. There’s no strict rule to govern here, but we can eliminate one choice in a time. First of all, notice the pronouns, “it” and “their”. They must help you something. Choice A. What does it refer to? If you say nothing, it is somehow inappropriate here. So eliminate A. Choice B. Always remember that in ETS sense, “being”, in most cases, including this one, is redundant. Jump to Choices D and E. What does their refer to? The only noun stated in the leading portion is the inability (of the French under Napoleon) so that their refers logically to nothing. C is the best.
- C. The problem of parallelism. You know that? But can you distinguish? The parallel structure here are (the firm has proposed)
installing.....and digging...... Also notice that “to lower....” is to modify installing so it is not part of the parallel structure.
- D. In standard writing, don’t leave that after predict. You have only C and D then. But C has no logical noun reference for it.
- D. Two topics you have to consider. (1) the number or the numbers. You’re wrong if you choose the former. Our logic is that the number is correct since it refers to a specific figure i.e.,, 500, 250.5 etc. Eliminate A - C. (2) The problem of redundancy. Raise and increase mean the same. Use only one. You have D left now.
- E. Formal writing requires that you use whether instead of if. Eliminate A & D. Being is redundant. Eliminate A - C. That’s it.
- C. Parallelism again, but a lot easier. The structure are receiving, fetching and exciting.
- B. Obviously, you can eliminate A & D with the more difficult. You need a superlative comparative here. To analyze not for analysis is the appropriate idiom. Eliminate C, while E is awkward.
