Identify the dependent clause in this sentence: 'The mother dog left her bed as soon as the puppies were ____.'

Correct Answer: B

Rationale: The correct answer is 'B: sleeping.' In the sentence, 'as soon as the puppies were sleeping' functions as the dependent clause. A dependent clause is a group of words that contains a subject and a verb but cannot stand alone as a sentence. Choices A, C, and D do not form a dependent clause in the sentence provided. 'Slept' (A) is a verb in the past tense, 'awake' (C) is an adjective, and 'sleep' (D) is a noun. Therefore, 'sleeping' (B) is the only choice that correctly forms the dependent clause in this sentence.

Correct Answer: A

Rationale: The correct answer is A because the phrase 'walking to school' seems to modify 'a dollar,' which is illogical. The intended meaning is that the child found the dollar while walking to school. In sentence B, the modifier is correctly placed at the beginning of the sentence, indicating that the child found the dollar while walking to school. Choices C and D do not contain any misplaced modifiers.

Correct Answer: B

Rationale: The correct answer is 'She was going to the store.' This sentence uses the correct form of the past continuous tense, which is appropriate for describing an action in progress in the past. Choice A is the only option that uses the correct verb form. Choice C uses the present perfect tense, which is not suitable for describing a past action in progress. Choice D is incorrect as it lacks the auxiliary verb 'has' in the sentence structure.

Correct Answer: B

Rationale: The correct sentence structure is 'The cat is sleeping on the mat.' This is a complete and grammatically correct sentence following a standard subject-verb-object structure. 'The cat' is the subject, 'is sleeping' is the verb, and 'on the mat' is the prepositional phrase describing where the action is taking place. Choices A, C, and D are incorrect. Option A is a sentence fragment lacking a verb; option C is a dependent clause lacking a main clause, and option D has a subject-verb inversion making it awkward and incorrect.
