Answer: A

• Error in A:  “Being a renowned neurosurgeon”, This creates a dangling modifier problem. It makes it sound like the hospital is the neurosurgeon, instead of Dr. Kapoor.
• Error in B: “the hospital invite Dr. Kapoor” Here, the verb is wrong. Subject = “the hospital” (singular), so it should be“invited”(past tense) or “invites” (present tense), not “invite”.

Grammar Rule:

Introductory participial phrases must logically and grammatically modify the subject of the main clause.

Corrected Sentence:

Dr. Kapoor, being a renowned neurosurgeon, was invited by the hospital to deliver a keynote address on advancements in brain surgery.

Therefore, option a is the correct answer.

Answer: B

• Error in B: After "decided," the correct pattern is "to + base verb" (decided to postpone), not gerund.
• Error in C: Idiomatic usage is "postpone until next Monday," not "to next Monday."

Grammar Rule:

Some verbs (decide, plan, agree) take infinitives, not gerunds

Corrected Sentence:

"The committee discussed and decided to postpone the meeting until next Monday, considering the unavailability of key members."

Therefore, option b is the correct answer.

Answer: C

• Error in A: The word "aiming" is a present participle, which makes the first part of the sentence a phrase rather than a complete clause. For a complete sentence, it should be a conjugated verb. The correct form should be "aim," as in "The new guidelines aim...
• Error in C: Parallelism is broken: "reduce" (base verb), "streamline" (base verb), but "improving" (gerund). It should be "improve" to match the structure.

Grammar Rule:

In a parallel list, all verbs should be in the same form.

Corrected Sentence:

"The new guidelines aim to reduce paperwork, streamline processes, and improve efficiency across all departments."

Therefore, option c is the correct answer.

Answer: B

• Error in B: With "Neither… nor," the verb agrees with the nearest subject — here "auditors" (plural), so it should be "were", not "was".
• Error in D: The clause "which findings" is incorrect; it should be "whose findings" to indicate possession.

Grammar Rule:

In "neither… nor" constructions, verb agreement follows the subject closer to the verb.

"Whose" is the possessive form used for people or things; "which" cannot show possession.

Corrected Sentence:

"Neither the finance director nor the auditors were willing to endorse the report, whose findings were found inaccurate."

Therefore, option b is the correct answer.

Answer: D

• Error in B: "Neither" is singular; it should be "has been functioning" instead of "have been functioning".
• Error in D: "Team": it is a collective noun and takes a singular verb unless stressing individuals. Here, it should be "is yet to respond".

Grammar Rule:

"Neither" takes a singular verb; collective nouns take a singular verb unless context demands plural.

Corrected Sentence:

"Neither of the laptops has been functioning well since they were delivered, and the customer service team is yet to respond."

Therefore, option d is the correct answer.

Answer: A

The phrase "coupled along with" is incorrect because it redundantly combines two expressions of addition:

• "coupled with" (formal and idiomatic)
• "along with" (neutral, also means in addition to)

Only one of these should be used.

• Option (a) is correct — “coupled with” is concise and formal, fitting a corporate context.
• Option (b) changes the idiomatic structure and weakens the formal tone.
• Option (c) is acceptable but not as precise as “coupled with.”
• Option (d) is incorrect — “coupled by” is non-standard in this context.
• Option (e) is wrong because the original contains redundancy.

Hence, (a) is the best choice.

Answer: B

The phrase "owing because of" is incorrect because it redundantly combines two causative expressions:

• "owing to" (formal)
• "because of" (neutral/informal)

Only one should be used. The correct idiomatic usage is "owing to" + noun phrase.

• Option (a) - this is missing the word "of" after "because", which is needed since it's followed by a noun phrase. It should be "because of."
• Option (b)correctly uses “owing to” followed by the noun phrase “the mediator’s skillful intervention…”.
• Option (c) is incorrect — “owing of” is ungrammatical.
• Option (d) repeats the redundancy error.
• Option (e) is wrong because the given sentence contains the redundancy “owing because of.”

Hence, (b) is the correct answer.
