She was so mad at her boyfriend, she __________ on him when he called.

Correct Answer: D

Rationale: 'Hung up' is correct because it is the proper phrasal verb used when referring to ending a phone call. In this context, the sentence implies that the woman ended the call abruptly due to being angry. 'Yelled' and 'Screamed' both suggest vocalizing loudly, which doesn't fit the situation described. 'Speak' is incorrect as it should be 'spoke' for proper verb tense agreement.

Correct Answer: C

Rationale: The correct answer is 'Was elected' as it is the passive voice construction needed in this context. The sentence is referring to an action that happened to John F. Kennedy (being elected president), so the passive voice 'was elected' is the appropriate form to use in this sentence. Choice A, 'Elected,' is incorrect because it is the active voice and does not fit the sentence structure. Choice B, 'Was electing,' is incorrect as it is the continuous form of the verb, which is not suitable in this sentence. Choice D, 'Had elected,' is incorrect because it implies a past perfect tense which is not required in this context.

Correct Answer: A

Rationale: The correct answer is A: 'As soon as the puppies were asleep' is the dependent clause in the sentence. It functions as an adverbial clause, indicating a time relationship with the action of the mother dog leaving her bed. Dependent clauses rely on independent clauses to form complete sentences and cannot stand alone. Choice B is incorrect because it separates the dependent clause. Choice C is incorrect as it is a noun phrase. Choice D is incorrect as it is an independent clause.

Correct Answer: C

Rationale: The correct answer is 'C: Did well.' This phrase is commonly used to describe performance on an exam. 'Worked' does not fit the context of exam performance. 'Forgot' is incorrect as it implies forgetting something related to the exam. 'Done good' is grammatically incorrect; the correct form is 'done well.' Therefore, 'Did well' is the most appropriate choice in this context.

Correct Answer: A

Rationale: The correct answer is 'Ask' because it maintains subject-verb agreement with 'two students,' requiring a plural verb 'ask' to match the plural subject. The other choices ('Is,' 'Was,' 'Could') do not agree with the plural subject and are thus incorrect. 'Is' is singular, 'Was' is the past tense form, and 'Could' indicates a possibility but does not fit the context of the sentence.
