Which choice completes the text so that it conforms to the conventions of Standard English?
Answer:
A
Explanation
Choice A is the best answer. The convention being tested is subject-verb agreement. The singular verb “is” agrees in number with the singular subject “His work.”

Choices B, C, and D: The plural verbs “were,” “have been,” and “are” do not agree in number with the singular subject “His work.”
✨ Expert's Tip ✨
- When the answer choices are verbs, be sure to first check out their agreement in number with the subject.
- It is smart to trim the sentence by crossing out the modifiers like prepositional phrases or words set off by commas.
