1. Two students _________ their professor about the possibility of obtaining a good grade in class.

• A. Ask
• B. Is
• C. Was
• D. Could

Correct answer: A

Rationale: The correct answer is 'Ask' because it maintains subject-verb agreement with 'two students,' requiring a plural verb 'ask' to match the plural subject. The other choices ('Is,' 'Was,' 'Could') do not agree with the plural subject and are thus incorrect. 'Is' is singular, 'Was' is the past tense form, and 'Could' indicates a possibility but does not fit the context of the sentence.

2. Select the word or phrase that makes this sentence grammatically correct. Before ________ this medicine, consume a modest meal.

• A. having taken
• B. taking
• C. took
• D. will take

Correct answer: B

Rationale: The correct form to use in this sentence is the present participle 'taking.' The sentence should read, 'Before taking this medicine, consume a modest meal.' It is important to use the present participle form when talking about an action that occurs before another action. Choice A 'having taken' is incorrect as it suggests a completed action before consuming a meal. Choice C 'took' is in the past tense, not suitable for indicating an action that should happen before another. Choice D 'will take' is in the future tense, which does not fit the context of the sentence.

3. Select the word or phrase that makes the following sentence grammatically correct. Two students ___________ the machine while the third oversaw their work.

• A. operate
• B. operating
• C. were operating
• D. has been operating

Correct answer: A

Rationale: The word 'operate' is the correct choice as it agrees with the verb tense used in the sentence. In this case, the sentence requires the simple past tense. The correct form should be 'Two students operate the machine while the third oversaw their work.' Choices B, C, and D are incorrect because they do not match the required verb tense for the sentence. 'Operating' (choice B) is a present participle, 'were operating' (choice C) is past continuous, and 'has been operating' (choice D) is present perfect continuous, none of which fit the context of the sentence.

4. Which word is used incorrectly in the following sentence? If you calculate too quickly, you may possibly fail to get the right answer.

• A. calculate
• B. quickly
• C. possibly
• D. right

Correct answer: B

Rationale: The word 'quickly' is used incorrectly in the sentence. The correct word that should be used here is 'speedily.' 'Quickly' is an adverb that describes the speed at which an action is performed. However, in this context, the sentence needs an adverb that conveys doing something in a hurried or rushed manner, which is 'speedily.' Therefore, the sentence should read as: 'If you calculate too speedily, you may possibly fail to get the right answer.' The other choices ('calculate,' 'possibly,' 'right') are used appropriately in the sentence and do not need to be changed.

5. Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.

• A. oneself
• B. itself
• C. herself
• D. themselves

Correct answer: B

Rationale: The correct answer is 'itself.' The sentence is referring to the centrifuge, which is an object, not a person. Therefore, the word 'itself' is used to indicate that the centrifuge cannot run on its own; it requires constant attention. Choices A, C, and D are incorrect because they refer to a person or people, which is not suitable in the context of the sentence.
