Correct Answer: B

Rationale: The correct answer is 'B: Do.' In the given sentence, the imperative form is used to give a command or instruction. The imperative form of the verb 'to do' is 'do,' which is commonly used in negative commands like 'Do not worry about it.'

Choices 'A: Is,' 'C: You,' and 'D: Was' do not fit grammatically or contextually in completing the sentence as they are not imperative verbs.

Correct Answer: C

Rationale: The word 'shear' means to cut, while 'sheer' in this context means 'complete' or 'unqualified.' The correct spelling in the sentence should be 'sheer.'
Choice A, 'peeked' is the correct past tense of 'peek,' meaning to glance quickly or briefly.
Choice B, 'through' is the correct preposition to indicate moving in one side and out the other.
Choice D, 'scene,' is the correct term for a part of a play or movie, not 'seen,' which is the past participle of 'see.'

Correct Answer: B

Rationale: An indirect quotation does not require quotation marks as it paraphrases what was said without directly quoting it. Sentence B, 'John F. Kennedy announced plans to go to the moon,' is an example of an indirect quotation as it conveys the information without using the exact words spoken by Kennedy.

Choices A, C, and D directly quote the individuals and thus require quotation marks, making them incorrect answers.

Correct Answer: A

Rationale: The correct contraction to use in this sentence is 'who's,' which is short for 'who is.' In the given context, 'who's' indicates the correct possessive form, clarifying that the clients are confused about who is in charge.
Choice B, 'Whos,' is incorrect as it does not use an apostrophe to indicate the omitted letter.
Choice C, 'Who'll,' is incorrect as it is a contraction for 'who will,' which does not fit the context of the sentence.
Choice D, 'Who,' is incorrect as it is not a contraction and does not clarify the intended meaning of the sentence.

Correct Answer: C

Rationale: The passage indicates that the writer is a student writing a first draft of a paper. The language used in the passage is informal and lacks precision, suggesting it is not written by a professional in a business environment or a researcher for a scientific journal. The focus on experimenting with hitting a golf ball also aligns more with a student exploring a topic rather than an established author of literature.
