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: A

Rationale: The correct answer is 'chiefs.' 'Chief' follows the standard rule for forming the plural by adding an 's' at the end. Choices B, C, and D are incorrect as they do not follow the standard pluralization rule for the word 'chief.' 'Chieves,' 'chievs,' and 'chiefes' are not valid plural forms of 'chief.'

Correct Answer: A

Rationale: The main idea of the paragraph is to highlight the dangers associated with coal mining. The sentence 'Coal miners risk injury and health issues on a daily basis' supports the concept that coal mining is a dangerous job. Choice B is incorrect as it focuses on cleanliness rather than safety. Choice C is incorrect as the location of coal mining is not the primary focus of the paragraph. Choice D is incorrect as it does not encompass the full extent of risks mentioned in the paragraph.

Correct Answer: A

Rationale: The subject 'Neither' is singular, so the correct verb form to use is 'is.' In this sentence, 'boys' is part of a prepositional phrase 'of the boys' and does not affect the verb agreement. 'Are' (choice B) is plural and does not match the singular subject. 'Were' (choice C) is past tense and not suitable for the present context. 'Be' (choice D) is an infinitive form and does not agree with the subject.

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.
