Question 1: Subject-Verb Agreement
The poet and novelist (a) / are being honored (b) / at the grand cultural fest tonight. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Look closely at the definite articles. Is there an article before “novelist”? If not, does the sentence describe one single individual or two different people?
Correct Answer: (b)
Correction: Change “are” to “is”.
Grammar Solution: Since the definite article “The” is only applied to the first noun (“poet”), both titles point to the same singular individual. Consequently, a singular verb is required.
Question 2: Subject-Verb Agreement
Five miles across the rough terrain (a) / are a long distance to walk (b) / before the sun sets. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Think about specific metrics like weight, currency, or distance. When they are considered as a unified collective measurement or single journey, do they take a singular or plural verb?
Correct Answer: (b)
Correction: Change “are” to “is”.
Grammar Solution: When a plural numerical noun denotes a specific quantity, distance, or time frame considered strictly as a single collective unit, the verb remains singular.
Question 3: Subject-Verb Agreement
Either the project manager (a) / or the developers (b) / is going to present the update. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: When subjects of mixed numbers (one singular, one plural) are linked by the correlative conjunction “either… or”, the verb must match the subject closest to it.
Correct Answer: (c)
Correction: Change “is” to “are”.
Grammar Solution: Rule of Proximity—when multiple subjects joined by “or” or “nor” differ in grammatical number, the verb must match the number of the closer subject (“developers”).
Question 4: Subject-Verb Agreement
Every manager and team lead (a) / were instructed to compile (b) / their weekly activity reports. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: The modifier “Every” treats a group as separate individuals. Check how it impacts verbs, even if multiple nouns are connected together with “and”.
Correct Answer: (b)
Correction: Change “were” to “was”.
Grammar Solution: Any noun phrase modified or qualified by the words “each” or “every” takes a strictly singular verb structure, even when connected using “and”.
Question 5: Subject-Verb Agreement
The standard package, along with (a) / multiple optional accessories, (b) / were shipped yesterday afternoon. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Intervening parenthetical phrases beginning with expressions like “along with,” “as well as,” or “together with” do not alter the number of the true sentence subject.
Correct Answer: (c)
Correction: Change “were” to “was”.
Grammar Solution: When a singular subject (“The standard package”) is joined with plural nouns using “along with”, the verb remains singular because it only agrees with the primary subject.
Question 6: Tenses & Auxiliaries
By the time the medical crew arrived, (a) / the critically injured patient (b) / passed away. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: When two sequential actions occurred in the past, use the Simple Past tense for the more recent action, and the Past Perfect tense for the action that completed first.
Correct Answer: (c)
Correction: Change “passed away” to “had passed away”.
Grammar Solution: When dealing with two distinct chronological past events, the action occurring earlier in time must be written in the Past Perfect tense ($had + V_3$).
Question 7: Tenses & Auxiliaries
He is working in this design lab (a) / for the last seven years (b) / as a senior consultant. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Pay close attention to the phrase “for the last seven years.” When an action started in the past and is still ongoing, a perfect continuous tense is required instead of a simple continuous tense.
Correct Answer: (a)
Correction: Change “is working” to “has been working”.
Grammar Solution: For actions that initiated in the past and are still ongoing, the Present Perfect Continuous tense must be utilized when a duration marker (“for/since”) is present.
Question 8: Tenses & Auxiliaries
If I was the President of the council, (a) / I would implement alternative policies (b) / without any hesitation. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: This sentence states an imaginary, hypothetical, or impossible current condition. Which specific past plural verb form is required for all singular pronouns in the subjunctive mood?
Correct Answer: (a)
Correction: Change “was” to “were”.
Grammar Solution: The past subjunctive mood marker (“were”) is completely mandatory for conditional or imaginary clauses, regardless of the subject being singular.
Question 9: Tenses & Auxiliaries
The director has not (a) / and will not accept (b) / any structural modifications to the script. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Both auxiliary markers (“has” and “will”) demand their own correct main verb forms. You cannot reuse the base form “accept” with the helping verb “has”.
Correct Answer: (a)
Correction: Change “has not” to “has not accepted”.
Grammar Solution: In compound sentences featuring distinct auxiliary verbs, each helper must link directly to its grammatically accurate main verb variant ($has + V_3$ and $will + V_1$).
Question 10: Tenses & Auxiliaries
You will be penalized (a) / for late submission (b) / if you do this again. (c) / No error (d)
(a) Part A
(b) Part B
(c) Part C
(d) No Error
Hint: Think about how modal verb usage changes when establishing an official threat, restriction, or penalty against second-person pronouns (“You”). Should it be “will” or “shall”?
Correct Answer: (a)
Correction: Change “You will” to “You shall”.
Grammar Solution: To deliver a clear structural warning, regulatory command, or explicit punishment within second or third-person contexts, “shall” replaces “will”.
