Which of the following sentences correctly uses a transition word?

Correct Answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

Correct Answer: C

Rationale: Choice C is the correct answer because it properly uses quotation marks to indicate a direct quote within the sentence ('My history presentation was great!'). Choices A, B, and D contain direct quotes but fail to use quotation marks, making them incorrect. In choice A, the direct question 'How was your day?' should be enclosed in quotation marks. In choice B, the direct quote 'It was awesome.' should also be enclosed in quotation marks. In choice D, the direct statement 'That's wonderful!' should be enclosed in quotation marks.

Correct Answer: A

Rationale: The correct answer is 'A: is.' In the sentence, 'Our family is staying home for the holidays this year,' the singular collective noun 'family' requires a singular verb to maintain subject-verb agreement. 'Is' is the correct singular form of the verb to match with 'family.' Choice B 'be' is incorrect as it is the base form of the verb and does not agree with the subject 'family.' Choice C 'am' is incorrect as it is a first-person singular form of the verb 'to be,' which does not align with the subject 'family.' Choice D 'are' is incorrect as it is a plural form of the verb and does not match with the singular subject 'family.'

Correct Answer: A

Rationale: The correct answer is 'Children's.' In this context, 'Children's' is the correct possessive form to indicate that the books belong to or are associated with children. Choice B ('Childrens's') is incorrect due to the unnecessary extra 's' after the apostrophe. Choice C ('Childrens'') is wrong as it is missing the apostrophe to show possession. Choice D ('Childrens') is incorrect as it is missing the apostrophe and does not form the possessive form correctly.
