Correct Answer: B

Rationale: The correct answer is B, 'lead.' The correct spelling should be 'led' in the context of the sentence. 'Lead' is a present tense verb, while 'led' is the past tense of 'lead' when used in the sense of guiding or showing the way. Choice A, 'attending,' is spelled correctly. Choice C, 'entourage,' is spelled correctly. Choice D, 'interns,' is spelled correctly. The error lies in the verb 'lead' being used incorrectly in the past tense form.

Correct Answer: A

Rationale: In this context, 'principle' is spelled incorrectly. The correct word should be 'principal,' which means main or primary. 'Principle' refers to a fundamental truth or belief. Choice B, 'role,' is correctly spelled. Choice C, 'provision,' is also spelled correctly. Choice D, 'convenient,' is spelled correctly as well. Therefore, the correct answer is A as it is the only word spelled incorrectly in the context of the sentence.

Correct Answer: B

Rationale: The correct word to use in this sentence is 'has' because 'One of the students' is singular, so it should be followed by a singular verb. The word 'has' is the correct singular form of the verb in this context. Choice A 'have' is plural, Choice C 'are' is also plural, and Choice D 'is' does not agree in number with the subject 'students'. Therefore, 'has' is the only correct choice here.

Correct Answer: D

Rationale: The word 'his' is the possessive form of the pronoun 'Mr. Menotti,' indicating that the belongings belong to him. Using 'her,' 'him,' or 'he' would not be grammatically correct in this context as they do not reflect the possession by Mr. Menotti. 'Her' would imply the belongings belong to his wife, 'him' is an objective pronoun, and 'he' is a subject pronoun, neither of which correctly shows possession.

Correct Answer: D

Rationale: The correct answer is 'D: will be given.' In the sentence, the future passive voice is needed to convey that Angela will receive the employee discount if she attends the seminar. 'Will be given' is the appropriate phrase to express this passive construction. Choices A, B, and C are incorrect as they do not form the correct future passive structure required in the sentence.
