Correct! The ‘if’ clause should be in the simple present tense (“If you go…”), not the future tense.

Incorrect. “More than one” is followed by a singular noun and takes a singular verb, so “have” should be replaced with “has”.

Incorrect. When two subjects are connected by ‘or’, the verb agrees with the closer subject. Since “her sisters” is plural, the verb should be plural (“feed”).

Incorrect. “Each” is a singular pronoun and always takes a singular verb, so “have” should be replaced with “has”.

Incorrect. The preposition “in” must be followed by a gerund (V1 + ing), so “take care of” should be replaced with “taking care of”.

Incorrect. The causative verb “make” is followed by a bare infinitive (verb without “to”) in the active voice, so “to see” should be replaced with “see”.

Incorrect. “Theirs” is a possessive pronoun and cannot be followed by a noun. Here, we need the possessive adjective “their” to modify “fun and enjoyment”.

Incorrect. The conjunction “so” shows a cause-and-effect relationship, which doesn’t make sense here. It should be replaced with a contrast connector like “but”.

Incorrect. This sentence requires parallel structure. Since “weather”, “sweaters”, “mood”, and “holidays” are all nouns, we must use the noun form “merriment” instead of the adverb “merrily”.

Incorrect. The noun “assurance” takes the preposition “of” or “about” when referring to the object of assurance. Therefore, “assurance with” should be replaced with “assurance of”.

Incorrect. When two singular subjects (“Heena” and “Teena”) are connected by “either… or”, the verb must be singular. Therefore, “are helping” should be replaced with “is helping”.

Incorrect. “The rich” represents the entire class of rich people and is treated as a plural noun, so it takes a plural verb. Therefore, “helps” should be replaced with “help”.

Incorrect. The adjective “fascinated” takes the preposition “by” or “with” instead of “of”. Therefore, “fascinated of” should be changed to “fascinated by”.

Incorrect. The correct idiomatic phrase is “hours spent at the desk,” not “from the desk.” Therefore, “from” should be replaced with “at”.

Incorrect. The sentence is grammatically correct. The conditional clause using “unless” is properly paired with the simple present tense (“puts in”).

Incorrect. The phrase “as per company policy” is a parenthetical element that should be set off by commas on both sides, but the first comma in part (A) is incorrectly placed after “entitled” instead of before “as per.” The correct structure is “are entitled, as per company policy, to additional compensation.” Example: “The students are eligible, as per university rules, for financial aid.” (Not: “The students are eligible, as per university rules for financial aid.”)

Incorrect. When the subject is followed by an additive phrase such as “along with,” “together with,” or “as well as,” the verb agrees with the main subject, not the words in the phrase. Here, the main subject is “The manager” (singular), so the verb should be “was” instead of “were.” Example: “The teacher, along with her students, was present at the event.” (Not: “The teacher, along with her students, were present at the event.”)

Incorrect. The adverb “hardly” is always paired with “when,” not “than.” The correlative pair “no sooner” is used with “than.” Therefore, “than” in part (A) should be replaced with “when.” Example: “She had hardly entered the room when the phone rang.” (Not: “She had hardly entered the room than the phone rang.”) Compare with: “No sooner had she entered the room than the phone rang.”

Incorrect. When the main clause uses the past perfect tense (“had complied”), a later action must be expressed in the simple past tense. Therefore, “is revised” should be replaced with “was revised.” Example: “The train had already left before we reached the station.” (Not: “The train had already left before we reach the station.”)

Incorrect. The relative pronoun “who” refers to its antecedent “authorities,” which is plural. Therefore, the verb must also be plural, and “is” should be replaced with “are.” Example: “The teachers who are dedicated inspire their students.” (Not: “The teachers who is dedicated inspire their students.”)
