Select the word or phrase that makes the following sentence grammatically correct. Miguel and I are waiting to ___________ with the doctor.

Correct Answer: D

Rationale: The verb 'meet' is the correct option in this context as it completes the sentence structure 'waiting to meet with the doctor' in a grammatically correct way. The sentence requires an infinitive verb form to convey the intended meaning of Miguel and I waiting to have a meeting or appointment with the doctor. Choices A, B, and C are incorrect because 'be met' changes the meaning, 'meeting' is a gerund form which doesn't fit the sentence structure, and 'met' is a past tense form that doesn't match the present tense context of the sentence.

Correct Answer: B

Rationale: The correct word to make the sentence grammatically correct is 'too.' In this context, 'too' means excessively or to a higher degree, indicating that the person is extremely uncomfortable and needs another pillow. 'To' is a preposition and does not fit the context of the sentence. 'Much' is an adverb used to refer to a large quantity, not the degree of discomfort. 'Lesser' is a comparative adjective, which is not suitable for expressing the level of discomfort in this sentence. Therefore, 'too' is the most appropriate choice to convey the intended meaning.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma. The sentence should be: 'Follow my lead, I have been performing this procedure for years.' The comma is necessary to separate the introductory phrase 'Follow my lead' from the main clause that follows. The other choices are incorrect because a period would create two separate sentences, an exclamation point is not suitable for the context, and a semicolon would be too strong of a punctuation mark for this sentence structure.

Correct Answer: B

Rationale: The verb 'raised' should be used in the past tense to match the past event (lecture was over). Therefore, the correct phrase is 'raised their hands to ask questions.' In English, when referring to a past event, the past tense of the verb is typically used to maintain proper grammar and clarity. Choice A is incorrect because it uses the present tense 'raise' instead of the past tense. Choice C is incorrect as it uses the present perfect tense 'have raised,' which is not suitable for a simple past event. Choice D is incorrect as it uses the present continuous tense 'are raising,' which is not appropriate for a completed past action.

Correct Answer: C

Rationale: The word 'initial' is used incorrectly in the sentence. The correct word that should be used here is 'initially.' 'Initially' is an adverb that is used to indicate the beginning or starting point of an action, while 'initial' is an adjective that describes something as happening at the beginning of a process. In this context, the correct usage would be 'He received an oral dose initially, followed by an IV drip.' The other choices ('received,' 'dose,' and 'followed') are used correctly in the sentence and do not need any corrections.
