Select the phrase in the sentence that is not used correctly. Until his trip to Puerto Rico, Javier had never seen his ancestral home.

Correct Answer: C

Rationale: The phrase 'never seen' in the sentence is not used correctly. The correct phrase should be 'never seen,' which is the past participle form of the verb 'see.' In this context, 'seen' is the correct past participle to use with 'had never.' Choice A, 'Until his trip,' is correct as it sets the time frame. Choice B, 'had never,' is also correct as it indicates the past perfect tense. Choice D, 'his ancestral home,' is also used correctly as it refers to the place Javier had never seen before.

Correct Answer: C

Rationale: The correct punctuation needed in the sentence is a colon. A colon is used to introduce a list or an explanation. In this case, the colon helps to indicate that the following phrase ('Remember the old saying') is providing an explanation or clarification related to the phrase before it. Choice A, the exclamation point, is incorrect as the sentence is not expressing strong emotion or excitement. Choice B, the apostrophe, is incorrect as it is not needed for possession or contraction. Choice D, the semicolon, is incorrect as it is used to connect two independent clauses, which is not the case here.

Correct Answer: B

Rationale: The sentence is in past tense ('As the concert ended'). Therefore, the correct verb form to use is 'asked,' as it agrees with the past tense of the sentence. Choice A is incorrect because 'ask' is not in agreement with the past tense context. Choice C is incorrect because 'have asked' is present perfect tense, not past tense. Choice D is incorrect because 'are asking' is present continuous tense, not past tense.

Correct Answer: C

Rationale: The word 'your' is used incorrectly in the sentence. The word 'your' is the possessive form that shows ownership, while 'you're' is a contraction of 'you are.' In this context, 'your' should be used to indicate that the packet belongs to the person. The correct sentence should be 'Follow the instructions you received in your packet.' The other choices ('Follow,' 'instructions,' and 'packet') are all used appropriately in the sentence and do not need any corrections.

Correct Answer: C

Rationale: In the sentence, 'The nursing staff appreciate occasional thank-you cards,' the pronoun 'them' is the best word to substitute for 'nursing staff.' The word 'them' is a pronoun that refers to a group of people or things, which matches the plural form of 'nursing staff.' Therefore, 'them' is the correct choice in this context. Choice A, 'They,' could also refer to the nursing staff, but 'them' is more precise in this case. Choice B, 'It,' is singular and does not match the plural 'nursing staff.' Choice D, 'Us,' refers to the speaker and others, which is not appropriate in this context.
