Answers:

649). OA - C - right tense

Explanation: George’s personal diary and album formed the basis of his book (that he wrote) about the places (that) he had visited.

Here perfect tense is unnecessary in the sentence "he wrote about the places that he (had) visited"

We can do without it since there is no confusion regarding the timeline.

Further, in the reduced form, construction in E, with perfect tense, is highlighting an inappropriate sequence of actions: he visited those places before his personal diary and album formed the basis of his book.

650). OA - E - idiomatic - both as X and as Y

A, B - incorrect - unidiomatic

C - incorrect - subject verb agreement - ...recent ideas(plural) based on Dr. Wren's studies suggests(singular) that....

D - incorrect - subject verb agreement - .... a skeletal structure(singular) that exist(plural) both as...

Answers:

659). (OG 10th Ques no - 3) - OA - B - Ques no 92

OE:
B - correct - preserves the sense of the original, uses the correct idiom, and observes the parallelism required among and within the three main verb phrases.
Because the verb phrases used to describe the bats' duties are governed by the phrase different duties such as, they should each be expressed in the present participial (or "-ing") form to parallel defending and scouting.

A, C, D, E - incorrect - violate parallelism by employing infinitives (to...) in place of participial phrases.

Answers:

661). (OG 10th Ques no - 32) - OA - B

OE: Choice B is best. Only B uses verb tenses correctly to indicate that construction of the buildings was completed prior to the earthquake.

A, C - incorrect - illogically state that some buildings were both destroyed and damaged; or is needed to indicate that each of the buildings suffered either one fate or the other. In using only one verb tense,were, A fails to indicate that the buildings were constructed before the earthquake occurred.

C, D - incorrect - use the present perfect tense incorrectly, saying in effect that the buildings have been constructed after they were destroyed last year.

E - incorrect - suggests that the construction of the buildings, rather than the earthquake, occurred last year, thus making the sequence of events unclear.

Answers:

683). (OG 11th Ques no - 50) - OA - D - has the main clause followed by one subordinate clause correctly introduced by that

OE: Although it is possible to begin a sentence with a subordinate clause beginning with that, this inverted construction often results in errors such as those found here. In the original sentence, the subordinate clause that.....technology is followed by the main verb, can..be said, but then the verb is followed by yet another subordinate clause, that it is their fault. The best way to solve this problem is by putting the sentence in the expected order, with the main clause (It can hardly be said) preceding the subordinate clause(that...) For greater clarity and concision, the two subordinate clauses should be condensed into one: educators are at fault for not anticipating the impact of microcomputer technology

A - incorrect - inverting the usual order results in an ungrammatical construction in which the main verb is both preceded and followed by a subordinate clause.

B - incorrect - can hardly be said to be at fault does not grammatically complete the subordinate clause

C - incorrect - construction that it is..who have not is wordy and awkward; it also distorts meaning and lacks completion

E - incorrect - the fact is wordy; the inverted construction does not successfully convey the meaning of the sentence.

684). OA - E - parallel - that X is..than that Y is... - That the new managing editor rose from the publication’s “soft” news sections to a leadership position is more of a landmark in the industry than that she is a woman

A, B - incorrect - violating parallelism, passive - use of being

C - incorrect - wrong comparison - comparing rising to womanhood

D - incorrect - wrong tense

C, D - incorrect - redundant - ...whether or not...

OE: B, the best choice, avoids errors of agreement, correctly uses the parallel construction that x and that y, and uses would rather than will to refer to a promised but uncertain future event.

A, C - incorrect - singular it after expected has no grammatical referent: its antecedent cannot be The company, but rather must be the plural
profits. A and C also contain errors of verb form, using will where would is required.
A, D - incorrect - fail to maintain parallel structure: properly formed, the construction would have that after expected to parallel that after announced. Furthermore, in D, the addition of them to is unnecessary.

E - incorrect - illogically uses the future perfect will have improved to suggest completion of an action that will be continuous in the second half of the year.

OE from OG 10th: Two instances of subject-verb agreement must be observed in this sentence: The period ... has been established and what is much more difficult to determine ... is. Both clauses have singular subjects and must have singular verbs.

indicates that the provision still applies. The phrase call... to consider is idiomatic, and to do so can substitute grammatically for it.
