John F. Kennedy was a senator before he _______ president in 1960.

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: In this context, 'Envelopes' is the correct choice as it refers to the items (envelopes) that the mailperson is responsible for delivering. The other choices are incorrect: 'Mail' (Choice B) is too general and does not specify the items to be delivered, 'Block' (Choice C) is the location and does not make sense in the context of delivering mail, and 'Every' (Choice D) is an adjective that does not complete the sentence logically.

Correct Answer: A

Rationale: The correct answer is 'Massive' as it accurately describes the size of the stage in relation to the performance. The word choice 'Massive' complements the context of a theater performance, highlighting the grandeur and scale of the stage. The other choices, 'Stunningly,' 'Lonely,' and 'Misery,' do not fit logically in the sentence as they do not relate to the physical attributes of the stage.

Correct Answer: D

Rationale: The correct answer is 'Were broken.' In this sentence, the subject 'glass in three of the windows' is plural, so the correct verb form should also be plural, which is 'were broken.' The verb 'broken' in the original sentence is in the past participle form, which is used correctly in the corrected answer choice 'D.' Choices A, B, and C are incorrect because they do not match the subject in number ('glass in three of the windows') and do not use the correct past participle form of the verb.

Correct Answer: A

Rationale: The correct answer is 'Play' because 'Children' is a plural subject and requires the base form of the verb. When referring to a plural subject like 'Children,' the verb should be in its base form without an added 's' or 'ed.' In this context, 'Play' is the appropriate form to use to match the subject 'Children.' Choice B, 'Plays,' is incorrect because it is the singular form of the verb and does not agree with the plural subject 'Children.' Choice C, 'Played,' is incorrect as it is the past tense form of the verb and does not fit the present tense context of the sentence. Choice D, 'Playing,' is incorrect as it is the present participle form of the verb and does not match the simple present tense needed in the sentence.

Correct Answer: A

Rationale: In this sentence, 'Oneself' is the correct reflexive pronoun to use when referring back to the singular subject 'a person.' It is important to match the reflexive pronoun with the singular noun. 'Yourself' and 'Themselves' are plural forms and do not agree with the singular subject 'a person.' 'Itself' is used for inanimate objects, not for people. Therefore, 'Oneself' is the most suitable choice in this context.

Correct Answer: C

Rationale: 'Carried' is correct because 'should never be' requires the past participle form of the verb 'carry' to complete the sentence properly. The sentence is in the passive voice, indicating that the action is being done to the scissors, not by them. Choices A, B, and D are incorrect as they do not form the correct past participle form needed in this context.

Correct Answer: A

Rationale: The correct sentence is 'Which one do you want?' Choice A is grammatically correct as it forms a question using 'which' to inquire about a specific choice. Choices B, C, and D contain errors in phrasing or grammar. Choice B includes a misspelling of 'want,' choice C uses 'whose' incorrectly, and choice D incorrectly combines 'who' and 'is' without proper context.

Correct Answer: B

Rationale: In this sentence, the word that best fits is 'warranted,' meaning that the symptoms did not justify or necessitate an emergency room visit. 'Desired' means wanted or wished for, 'Guaranteed' means assured, and 'Should have been' is not the appropriate phrase in this context. Therefore, 'warranted' is the correct choice for this question.
