readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
completing
B
to complete
C
completed
D
they completed
Correct Answer: C
Choice C is the best answer. This question tests parallel verb tense.
- Context clues: The series uses past tense verbs: "studied," "reviewed."
- Meaning: Verbs in a series must be parallel in form.
- Verify: "studied, reviewed, and completed" maintains past tense parallelism.
💡 Strategy: Keep verbs in a series parallel in tense and form.
Choice A is incorrect because "completing" is a gerund/present participle. Choice B is incorrect because "to complete" is an infinitive. Choice D is incorrect because it adds an unnecessary subject.
