readingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
six month
B
six months'
C
six-month's
D
six months
Correct Answer: B
Choice B is the best answer. This question tests apostrophe usage with plural time expressions.
- Context clues: The investigation lasted six months—plural time expression.
- Meaning: Time expressions use possessive apostrophes.
- Verify: "After a six months' investigation" correctly shows plural time possession.
đź’ˇ Strategy: Time expressions use possessive forms: singular = 's, plural = s'.
Choice A is incorrect because it lacks proper structure and possessive. Choice C is incorrect because the hyphenated form doesn't use an apostrophe this way. Choice D is incorrect because time expressions as modifiers need possessive apostrophes.
