readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
professors
B
professors'
C
professor's'
D
professor's
Correct Answer: D
Choice D is the best answer. This question tests apostrophe placement for singular possession.
- Context clues: "Her" later in the sentence indicates one person (singular).
- Meaning: For singular nouns, add 's to show possession.
- Verify: "The professor's innovative approach" correctly shows singular possession.
💡 Strategy: For singular possessives, add 's regardless of what letter the word ends with.
Choice A is incorrect because it lacks any possessive marker. Choice B is incorrect because "professors'" indicates plural possession. Choice C is incorrect because "professor's'" is not standard English.
