In the sentence, "Though asked frequently, I never answer." the first haf of the sentence is a modifying phrase (describing I). Therefore, parallelism is not relevant. In the question regarding sunspots, however, although is creating a contrast in the main clause of the sentence. Therefore...

The problem with "although never sighted at" really comes down to bad parallelism. The word "although" means there's a contrast, which means the two things that are contrasted must be parallel. In C, the first part of the contrast is "appear on the surface of the sun..."...

Not many lessons to take away from this question. The use of the pronoun "it" is not appropriate in this sentence. In fact, all of the answer choices are wrong for one reason or another. Whoever wrote this question does not have a good grasp on the English language, as there is a bad idiom...

On verbal, you're right that average question times vary more than on the Quant section. To counteract this somewhat, you can check in on your timing after 8 questions. There are 41 questions on the verbal section, which means that 8 questions is about 1/5 of the section. In 75 minutes, that means t...

On Reading Comprehension, difficult wrong answers are often wrong because just one word in that choice does not match the information in the passage. On Sentence Correction, clarity and ...

In this sentence, you want to make it clear that the legislation changed private contracts. In choices (B) and (C), the gerund (nullifying and changing) is not specific enough; it could describe either the legislation or the parliament. Conversely, "which" must refer to the preceding noun,...

The first issue you can tackle on this problem is the correct way to construct an idiom using "allow." "allow X" and "allow for X" are both good idioms. "allow that," on the other hand, is not correct. so you can eliminate (D). Similarly, "allow X to be p...
