Identify the sentence that contains a dependent clause.

Correct Answer: B

Rationale: The correct answer is B: 'The cat sat on the mat after it ate.' 'After it ate' is a dependent clause because it cannot stand alone as a sentence. It is dependent on the main clause 'The cat sat on the mat.' Choice A is a simple sentence without a dependent clause. Choice C is a sentence with a time adverbial modifying 'The cat will sit on the mat,' not a dependent clause. Choice D is a sentence in the present continuous tense, also lacking a dependent clause.

Correct Answer: C

Rationale: Choice C, 'The dog's tail wagged,' is the correct use of the apostrophe to show possession. In this sentence, the apostrophe is used correctly to indicate that the tail belongs to the dog. Choice A is incorrect as 'it's' is a contraction of 'it is' or 'it has,' not possessive. Choice B is also incorrect as 'Its' should be 'It's' to mean 'It is' or 'It has.' Choice D is incorrect as 'Its'' is grammatically incorrect; the correct form would be 'It's' if it were a contraction or 'Its' if it indicated possession without an apostrophe.

Correct Answer: A

Rationale: The correct answer is A. A compound sentence consists of two independent clauses joined by a conjunction or a semicolon. In sentence A, 'The sky is clear' and 'the stars are bright' are two independent clauses joined by the conjunction 'and.'<br>Choice B is a complex sentence as it has a dependent clause ('Although it was late') and an independent clause ('he stayed up').<br>Choice C is a simple sentence with only one subject and one verb.<br>Choice D is a complex sentence with a dependent clause ('While she reads') and an independent clause ('she listens to music').

Correct Answer: B

Rationale: The correct answer is B. Parallel structure ensures that items in a series or list are in the same grammatical form. In choice A, 'to run' disrupts the parallel structure since 'hiking' and 'swimming' are gerunds. Choice C similarly breaks the parallelism by using 'to swim' in a different form. Choice D is incorrect because it lacks consistent parallelism, as 'hiking' is not followed by gerunds like 'swimming' and 'running.' Therefore, only choice B maintains proper parallel structure by using gerunds ('hiking,' 'swimming,' and 'running') consistently.

Correct Answer: A

Rationale: The subject 'Neither' is singular, so the correct verb form to use is 'is.' In this sentence, 'boys' is part of a prepositional phrase 'of the boys' and does not affect the verb agreement. 'Are' (choice B) is plural and does not match the singular subject. 'Were' (choice C) is past tense and not suitable for the present context. 'Be' (choice D) is an infinitive form and does not agree with the subject.
