Option (D)

The problem with the original sentence is separately. Separately is an adverb but in this context it’s not clear exactly which verb it’s modifying. (A) and (B) share the same problem.

(C) and (D) both bring out the parallelism in the sentence, which you can see if you rewrite the sentence: “One benefit of learning to speak a language while learning to read it rather than as/in a separate process is . . . .”. You’ll notice that (D) changes process to the plural processes and undermines the parallelism; the underlined portion should refer to only one process, that of learning to speak a language, in order to create a parallel alternative to while learning to read it.

Hence, (D) is more appropriate.

The original sentence incorrectly pairs an infinitive ("to approach") with a clause ("that they should...") in the construction "either X or Y." Moreover, the use of "like" in the phrase "to approach mathematics like a creative activity" is incorrect. “Like” is used to compare the similarities between things, while “as” is used in comparisons that show equality. In this case, mathematics is a creative activity; thus, “as” is necessary.

(A) This choice is incorrect as it repeats the original sentence.

(B) While this choice does contain proper parallel structure, it incorrectly uses "like" instead of "as" in the phrase "to approach mathematics like a creative activity".

(C) CORRECT. The construction "either X or Y" requires parallelism between X and Y. In choice C, X and Y are parallel infinitive phrases ("to approach . . ." and "to force . . .").

(D) While this choice does create a parallel construction, it awkwardly begins the parallel elements with the words "that they" instead of the infinitive "to." Moreover, this choice incorrectly uses "like" instead of "as" in the phrase "to approach mathematics like a creative activity".

Option (C)

To deal with the sentence successfully you first need to consider its meaning. The sentence lists  five items, four of which support the claim that cats’ needs are “simple and largely inexpensive.”

You know that the fifth item, the trips to the vet, aren’t part of this list and shouldn’t be parallel with it because, first, the and before shelter suggests that the initial list ends with shelter and, second, trips to the vet are not inexpensive. Therefore, the final item needs to be expressed as an exception. Eliminate (A). At this point, the primary problem is one of expression. veterinarian visits, while shorter, is less clear and idiomatic than visits to the veterinarian. Out with (B). As for (D), we have a dangling modifier: who is occasionally visiting the vet? Eliminate. Hence (C) it is.

Option (A)

Audience is what’s called a collective noun because, like jury or family it describes a group of people that functions as a singular subject; one says the family is rather than the family are.

Therefore, the singular was is the correct verb for audience and you can eliminate (B) and (C).

Next, you have to decide among for the attendees, for they, and as is clear since its attendees.

(D) has a pronoun error since they has no clear referent. The singular audience wouldn’t work as the referent, and the sentence doesn’t provide us with any other options.

Pen in the first sentence refers to an enclosure for sheep. In the second sentence it refers to a female swan. In the third sentence it is a verb meaning ‘to write’. The fourth sentence is wrong because ‘great people of pen’s is incorrect usage.

ANS:option D

In sentence 1 ‘even’ is an adverb (qualifying stronger) used to emphasize something unexpected. In the second sentence ‘even’ means equal. The third sentence is wrong as the intended meaning is to ‘get even’.

ANS:

To ‘give away' means something given free. Hence loans cannot be given away.

ANS:option C

The word 'bolt' has been used correctly in choices (a), (c) and (d). A 'bolt of silk' refers to silk wound around a long metal tube. 'Bolt' as used in option (d) means 'to escape'. However the usage is inappropriate in choice (b). 'Bolt' means to 'make a dash for'; a person cannot make a bolt for the gate when he is unable to move.

'Passing marks' is erroneous. It should have been 'pass marks' instead.             

The usage in sentence (a) is incorrect because "reduce" is a better fit in the context, instead of "help". All other sentences are correct.
