Correct Answer: C

Rationale: The word 'our' is the best substitute for the underlined words 'the doctor's and my' in the sentence. Using 'our' indicates joint possession, making the sentence more concise and natural. Choice A, 'his', is singular possessive and does not reflect the joint ownership implied by the sentence. Choice B, 'their', is plural possessive and does not align with the singular subjects 'the doctor and I'. Choice D, 'mine', is possessive for the first person singular pronoun and does not convey the shared ownership of the notes by both individuals.

Correct Answer: D

Rationale: The word 'although' is the best fit in the sentence because it indicates a contrast between the fact that the emergency room was not busy last night and the head nurse's decision not to let anyone end her shift early. 'Although' sets up a contrast by acknowledging the first part of the sentence while introducing the surprising or unexpected information that follows. Choices A, B, and C do not provide the appropriate contrast needed in this context. 'Because' implies causation, 'Provided that' implies a condition for something to happen, and 'As if' implies a comparison rather than a contrast.

Correct Answer: C

Rationale: The correct word to use in this sentence is 'taking' to show the continuous aspect of the action. The sentence should read: 'Having taking one pill at bedtime, the patient was able to sleep for eight hours.' 'Taking' is the present participle form of the verb 'take,' which is appropriate in this context to indicate the ongoing action of taking a pill at bedtime. Choice A, 'took,' is incorrect as it is the simple past tense, not suitable for this sentence's structure. Choice B, 'take,' is the base form of the verb, which does not fit the sentence's requirement for a participle. Choice D, 'taken,' is the past participle form, which is also unsuitable for showing the ongoing action required in this context.

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.

Correct Answer: C

Rationale: The correct answer is C. The sentence requires an infinitive form of the verb 'to conduct' after the verb 'promised.' This structure is commonly used in English grammar, where the main verb 'promised' is followed by an infinitive verb form. Therefore, the sentence should read: 'The students promised to conduct themselves with quiet dignity.' Choice A ('conduct') is incorrect as it is not in the infinitive form required after 'promised.' Choice B ('conducting') is incorrect as a gerund does not fit the grammatical structure of the sentence. Choice D ('to be conducted') is incorrect as it changes the meaning of the sentence, suggesting that someone else will conduct the students, rather than the students conducting themselves.
