Correct Answer: A

Rationale: The phrase 'as long as' is used to indicate a condition that needs to be met for the main clause to happen. In this sentence, the radiology department sends Troy to pick up lunch only if it isn't too busy at the office, so 'as long as' is the most suitable phrase to convey this conditional relationship. Choice B, 'as if,' implies a hypothetical comparison rather than a condition. Choice C, 'after,' suggests a sequence of events rather than a condition. Choice D, 'unless,' introduces a negative condition which does not fit the context of the sentence.

Correct Answer: B

Rationale: The sentence is written in the first-person point of view, so the appropriate pronoun to use as a substitute for 'Francesca, Bill, and I' would be 'we.' This choice maintains the correct subject-verb agreement and ensures consistency in the sentence structure by keeping the pronoun in the nominative case. Choice A, 'They,' is incorrect as it changes the subject of the sentence, leading to a lack of agreement between the pronoun and the verb. Choices C and D, 'Them' and 'Us,' are both objective pronouns and do not fit the role of the subject in this sentence.

Correct Answer: A

Rationale: The word 'oneself' is a reflexive pronoun that refers back to the subject of the sentence, allowing the sentence to be grammatically correct. Options B and C, 'oneselves' and 'hisself,' are not standard English words. Option D, 'themselves,' is a plural pronoun and does not agree with the singular noun 'one' in the sentence.

Correct Answer: A

Rationale: The subject of the sentence 'The hockey team' is singular, so the correct verb to use is 'is' to maintain subject-verb agreement. In this case, 'is' agrees with the singular subject 'team,' making the sentence grammatically correct. Choices B, C, and D are incorrect as they do not agree with the singular subject 'team.' 'Are' is plural, 'be' is not the correct form of the verb to use in this context, and 'were' is past tense which is not suitable for the present tense sentence.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is used to indicate the end of a sentence. In this case, the sentence 'After you complete your rounds, please check in at the station.' is a complete thought and requires a period at the end to show that it is a complete sentence. The other choices are incorrect because a comma would not be suitable at the end of a sentence, a colon is used to introduce a list or an explanation, and a semicolon is used to connect two closely related independent clauses.
