After a _______ delay, the construction project finally resumed with renewed vigor.
Which choice completes the text so that it conforms to the conventions of Standard English?
three months'
three month's
three months
three-months'
Correct Answer: A
Choice A is the best answer. This question tests apostrophe usage with plural time expressions.
- Context clues: The delay lasted "three months"—plural possessive.
- Meaning: Time expressions use possessive apostrophes (one day's work, two weeks' vacation).
- Verify: "A three months' delay" correctly shows plural possession for a time expression.
💡 Strategy: Use possessive form for time expressions: singular = 's (day's), plural = s' (months').
Choice B is incorrect because "month's" is singular, but "three" indicates plural. Choice C is incorrect because time expressions functioning as adjectives need possessive apostrophes. Choice D is incorrect because the hyphen is unnecessary and "months'" doesn't need modification.
