Correct Answer: A

Rationale: The correct answer is A. In this sentence, the subject 'all of the board members' is plural, and the verb 'are' agrees with it. In choice B, 'each of the students' is singular, so the verb should be 'was' instead of 'were.' Choice C should use 'is' instead of 'are' since 'neither of the children' is singular. In choice D, 'any of the brownie recipes' is singular, so 'is' should be used instead of 'are.' Therefore, only choice A demonstrates proper subject-verb agreement.

Correct Answer: C

Rationale: The correct sentence uses lowercase 'summer' and capitalizes 'Niagara Falls.' Choice A incorrectly capitalizes 'Summer,' while Choice B incorrectly capitalizes 'niagara falls' and should have 'New York' capitalized. Choice D incorrectly capitalizes 'Summer' and 'new york.'

Correct Answer: D

Rationale: Bi, re, and un are prefixes, not suffixes. Prefixes are added at the beginning of base words to change their meanings. Therefore, choices A, B, and C are incorrect because they refer to suffixes or emphasize, which is not the case for these prefixes.

Correct Answer: C

Rationale: The correct structure is 'whom to hold responsible' as 'whom' is the object of the verb 'to hold.' In choice A, 'who' should be 'whom' to indicate the object of the verb. Choice B is incorrect as 'whom' is incorrectly placed before 'was responsible.' Choice D is also incorrect due to the awkward phrasing and the use of 'on' which is unnecessary.

Correct Answer: C

Rationale: The correct answer is C: Planning, brainstorming, outlining. During the prewriting phase of the writing process, it is essential to plan your writing, brainstorm ideas, and create an outline before moving on to drafting. Researching, referencing sources, and editing are typically part of the later stages of the writing process, not prewriting. Choices A, B, and D include elements that are more aligned with drafting and revising stages rather than prewriting.
