Select the word that makes the following sentence grammatically correct. Mary Ann gave ______ credit for studying so hard and passing the test.

Correct Answer: C

Rationale: The correct answer is 'C: herself.' In this sentence, 'herself' is the reflexive pronoun that correctly refers back to Mary Ann. It shows that Mary Ann is giving credit to herself for studying hard and passing the test. The use of 'oneself' (choice A) would be incorrect here as it is too general and does not specify Mary Ann. Choices B and D ('itself' and 'themselves') are also incorrect because they do not match the singular subject 'Mary Ann.' Therefore, 'herself' is the only option that fits both grammatically and contextually in this sentence.

Correct Answer: C

Rationale: The phrase 'and new tires' is misplaced in the sentence as it disrupts the flow of information. It introduces unnecessary detail that does not directly contribute to the main point of the sentence, which is identifying the ownership of the car. Choices A, B, and D are all essential parts of the sentence that help convey the location of the car and its ownership, making them correctly placed within the sentence.

Correct Answer: A

Rationale: The correct word to use in this sentence is 'volunteered' as it indicates an action that Cathy did in the past. The sentence suggests that Cathy was engaging in volunteering at the hospital for the first time, so the past tense form 'volunteered' is the most appropriate choice. Choice B ('volunteering') is incorrect because it is the present participle form and does not fit the past tense context of the sentence. Choice C ('was volunteered') is passive voice and implies that someone else made Cathy volunteer, which is not the intended meaning. Choice D ('volunteer') is incorrect as it is the base form of the verb and does not match the past tense requirement of the sentence.

Correct Answer: D

Rationale: The phrase 'in the auditorium' is misplaced in the sentence because it suggests that the dangers of drugs and alcohol were in the auditorium, which is not the intended meaning. It would make more sense for this phrase to come immediately after 'he informed us' to indicate where the presentation took place. Choices A, B, and C are all correctly placed within the sentence, providing necessary information about the context and topic of the presentation.

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: B

Rationale: The sentence starts with 'Before I had finished supper,' indicating that the action of James texting you on your cell phone had occurred before the completion of another past action (finishing supper). The past perfect tense 'had texted' is used to express an action that happened before another action in the past, making the sentence grammatically correct. Choice A is incorrect because it uses the present continuous tense, which is not suitable for indicating an action that occurred before finishing supper. Choice C is incorrect as it uses the simple present tense, which does not convey the sequence of events correctly. Choice D is incorrect as it presents the present continuous tense, which is not appropriate for the context of the sentence.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma. A comma should be placed after 'festivities' to separate the two independent clauses in the sentence: 'In addition to the hospital's regularly scheduled festivities' and 'the custodians celebrate with a party of their own.' The comma helps in improving the clarity and structure of the sentence by indicating a pause between the clauses. Choice A, 'Period,' is incorrect because a period would create two separate sentences rather than connecting the related clauses. Choice C, 'Apostrophe,' is incorrect as there is no need for an apostrophe in this context. Choice D, 'Semicolon,' is incorrect because a semicolon is used to join closely related independent clauses, which is not the case in the given sentence.

Correct Answer: B

Rationale: In the sentence 'One out of four doctors,' the subject is 'One,' which is singular. Therefore, the verb that follows should also be singular. The correct verb form in this case is 'subscribes,' not 'subscribe' or any other form. This subject-verb agreement rule ensures that the sentence is grammatically correct. Choice A 'subscribe' is incorrect as it is in the plural form and does not agree with the singular subject. Choice C 'subscribing' is in the gerund form and does not function as the main verb of the sentence. Choice D 'are subscribed' is in the passive voice and does not match the active voice required in this sentence.

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.
