Grammar & Sentence Mechanics
Q1: Which of the following sentences demonstrates correct subject-verb agreement?
A. The group of students are studying for their exams.
B. Neither the teacher nor the students was prepared for the fire drill.
C. Each of the essays has been graded and returned to the students. [CORRECT]
D. The data suggests that more research are needed.
Correct Answer: C
Rationale: Correct because "each" is a singular indefinite pronoun requiring a singular
verb ("has been graded"). Option A incorrectly uses plural "are" with singular "group,"
Option B incorrectly uses singular "was" when "students" (the closer subject) should
trigger plural "were," and Option D incorrectly uses plural "are" with singular "research."
Q2: Identify the grammatical error in the following sentence: "Running down the street,
the dog chased the mailman who was barking loudly."
A. Incorrect verb tense
B. Misplaced modifier [CORRECT]
C. Subject-verb disagreement
D. Pronoun-antecedent disagreement
Correct Answer: B
Rationale: Correct because the participial phrase "Running down the street" illogically
modifies "the dog" when it should modify "the mailman," creating a misplaced modifier
,that suggests the dog was running down the street while barking. The phrase needs
repositioning to clearly modify the intended subject.
Q3: Which sentence contains a fragment?
A. Although the deadline was extended, many students still submitted late work.
B. The professor accepted the assignment because it was well-written.
C. Because the library closed early. Which forced us to find another study location.
[CORRECT]
D. We studied at the coffee shop after the library closed early.
Correct Answer: C
Rationale: Correct because "Because the library closed early" is a dependent clause that
cannot stand alone as a complete sentence, and "Which forced us to find another study
location" is another dependent clause lacking an independent clause to complete the
thought. Together they form a fragment, not a complete sentence.
Q4: Select the sentence that uses parallel structure correctly.
A. The student enjoyed reading, to write, and painting in her free time.
B. The student enjoyed reading, writing, and to paint in her free time.
C. The student enjoyed reading, writing, and painting in her free time. [CORRECT]
D. The student enjoyed to read, writing, and painted in her free time.
Correct Answer: C
Rationale: Correct because parallel structure requires all items in a series to use the
same grammatical form; "reading," "writing," and "painting" are all gerunds, maintaining
consistency. The other options mix infinitives, gerunds, and past tense verbs, breaking
parallel structure.
Q5: Which sentence correctly uses pronoun-antecedent agreement?
, A. Every student must bring their own laptop to class.
B. Each writer should proofread their essay before submission.
C. All students must bring their own laptops to class. [CORRECT]
D. Neither the boy nor the girl brought their book to class.
Correct Answer: C
Rationale: Correct because "All students" is a plural antecedent that agrees with the
plural pronoun "their" and plural noun "laptops." Options A and B use singular
antecedents with plural "their" (though colloquially common, this is grammatically
nonstandard in formal academic writing). Option D should use "his or her" or restructure
to plural for agreement.
Q6: Identify the type of grammatical error in this sentence: "The student who studied
hard for the exam and they passed with flying colors."
A. Comma splice
B. Run-on sentence
C. Faulty pronoun reference [CORRECT]
D. Dangling modifier
Correct Answer: C
Rationale: Correct because the relative pronoun "who" introduces an adjective clause
modifying "The student," but "they" is an unnecessary and incorrect pronoun that
disrupts the clause structure. The sentence should read "The student who studied hard
for the exam passed with flying colors," eliminating the faulty "they."
Q7: Which of the following is a run-on sentence?
A. The semester ended, and the students celebrated their achievements.
B. The semester ended; the students celebrated their achievements.
C. The semester ended the students celebrated their achievements. [CORRECT]
D. Because the semester ended, the students celebrated their achievements.
