Correct option: B — (2)

(2) - were ready for the sudden fire drill 'Were' should be replaced with 'was'. When 'neither... nor' connects two subjects, the verb agrees with the subject closest to it. In this case, 'the teacher' is singular, so the verb should be singular ('was'). Hence, 'was ready for the sudden fire drill' is the most appropriate answer.

Correct option: B — (2)

(2) - remains a contentious subject ‘Remains’ must be replaced with ‘remain’. The subject of the sentence is ‘The profound implications’ (plural). The phrase ‘a field still largely inscrutable to the uninitiated’ provides additional information about ‘quantum theories’ but does not change the number of the main subject. Therefore, a plural verb is required. Hence, ‘remain a contentious subject’ is the most appropriate answer.

Correct option: B — (2)

(2) - ranging from sustainable infrastructure to social equity, often demands ‘Demands’ must be replaced with ‘demand’. The subject of the sentence is ‘The myriad challenges’ (plural). The phrase ‘confronting modern urban planners’ is a participial phrase modifying the subject and does not change its number. Therefore, a plural verb is required. Hence, ‘often demand’ is the most appropriate correction.

Correct option: C — (3)

(3) - before the deadline, and they shall submits ‘Submits’ must be replaced with ‘submit’. When using modal verbs like 'shall' (or 'will', 'can', 'may', etc.), the main verb that follows must be in its base form. Therefore, 'shall submit' is the correct form. Hence, 'and they shall submit' is the most appropriate correction.

Correct option: C — (3)

(3) According to the 'Rule of Parallelism', two or more words or phrases in a list must be in the same form. In the given sentence, "increasing membership" and "improving communication channels" are gerund phrases. "To foster a sense of community" is an infinitive phrase. To maintain parallelism, the third item should also be a gerund phrase. Hence, "and fostering a sense of community" is the most appropriate answer.

Correct option: C — (3)

(3) According to the 'Subject-Verb Agreement Rule', a singular subject always takes a singular verb and a plural subject always takes a plural verb. In the given sentence, the main subject is "The unique challenges," which is plural. Therefore, the verb should also be plural ("make") instead of singular ("makes"). Hence, "make its successful completion" is the most appropriate answer.

Correct option: B — (2)

(2) and promoting critical scholarship ‘Both … and’ is a fixed conjunction pair and the same part of speech should be used after each. Therefore, ‘promoting’ must be replaced with ‘promote’ to match the form of the verb ‘preserve’. Hence, ‘and promote critical scholarship’ is the most appropriate answer.

Correct option: C — (3)

(3) - are increasingly becoming a topic ‘Are’ must be replaced with ‘is’. The subject of the sentence is ‘The profound impact’ (singular). Therefore, a singular verb is required. Hence, ‘is increasingly becoming a topic’ is the most appropriate answer.

Correct option: C — (3)

(3) - but also it was thoroughly tested ‘Not only … but also’ is a fixed conjunction pair and the same part of speech is used after them. As there is an adjective after ‘not only’,, we need to use an adjective after ‘but also’. Therefore, ‘it was’ must be removed. Hence, ‘but also thoroughly tested’ is the most appropriate answer.

Correct option: C — (3)

(3) - remain a subject of intense debate The error is in subject-verb agreement. The subject of the sentence is the noun clause "What the ancient philosophers believed about the nature of reality and the purpose of human existence." Even though it describes multiple concepts, the clause itself functions as a singular entity. Therefore, the verb should be singular, "remains". Hence, ‘remains a subject of intense debate’ is the most appropriate answer.
