Which of the following sentences correctly uses apostrophes?

Correct Answer: A

Rationale: Choice A, 'Our home's roof needs repairing,' is the correct answer as it correctly uses the apostrophe to indicate possession. In this sentence, the apostrophe is used to show that the roof belongs to the home. Choice B is incorrect because it should be 'My grandparents' families' to show that multiple families belong to the grandparents. Choice C is incorrect as the sentence should be 'There are many parks located across the country' without using an apostrophe. Choice D is incorrect because it should be 'All of the women's things' to indicate possession by the women.

Correct Answer: C

Rationale: The sentence is a direct question as the speaker is asking if the person will send a postcard from Germany. Therefore, the correct punctuation mark to use at the end of a question is a question mark. An exclamation mark (Choice D) is used to convey strong emotion or surprise, which is not the case here. A period (Choice A) is used for declarative statements. A colon (Choice B) is used to introduce a list or explanation, which is not needed in this context.

Correct Answer: D

Rationale: The correct answer is 'Mid-America.' It is correctly hyphenated as it combines 'Mid' and 'America' to form a compound noun. Choice A, 'Ex-president,' should be hyphenated to show the prefix 'Ex-' before 'president.' Choice B, 'Hyperactive,' should not be hyphenated as 'hyper' is a prefix. Choice C, 'Self-made,' should be hyphenated to connect 'self' and 'made' in this compound adjective.

Correct Answer: B

Rationale: The correct answer is an exclamation mark because it is used to convey strong emotion or excitement, which is appropriate for the sentence. A comma is not suitable here as it does not convey the level of excitement expressed in the sentence. A semicolon is used to join independent clauses or separate items in a list, which is not required in this context. A question mark would be incorrect as the statement is not a question but rather an expression of excitement.

Correct Answer: C

Rationale: The correct answer is 'But.' In this sentence, the conjunction 'but' is used to show a contrast between the usual routine of taking a walk after breakfast and the fact that it was raining today. 'While' suggests a concurrent action, 'Because' implies causation, and 'When' introduces a time relationship, none of which are suitable in this context.
