Correct Answer: B

Rationale: The correct answer is B. This sentence effectively follows the conventions of standard written English by clearly presenting the subject ('The two brothers, Wilbur and Orville Wright') and the verb ('tested') with appropriate punctuation. Choice A introduces an unnecessary comma and could be more concise. Choice C changes the tense of the verb to 'were testing,' which is not required for the context provided. Choice D creates a more awkward sentence structure by placing the location at the beginning and using 'came and tested,' which is less direct than 'tested'. Thus, Choice B is the most effective and grammatically correct option.

Correct Answer: C

Rationale: Choice C, 'Other historians claim that the symbolism in the fairy tale is more about nature and the shifting seasons,' demonstrates the correct use of an apostrophe. The apostrophe in 'season's' indicates the possessive form of 'seasons,' correctly showing ownership by the shifting seasons. Choices A, B, and D do not showcase the correct use of an apostrophe. Choice A incorrectly uses 'fairy's' instead of 'fairies,' which is the plural form of 'fairy.' Choice B uses 'historians'' which is correct for the possessive form but does not relate to the use of an apostrophe. Choice D correctly uses 'Tchaikovsky's' to indicate possession by Tchaikovsky.

Correct Answer: A

Rationale: Choice A demonstrates correct punctuation. The sentence uses a colon to introduce a list, which is the most appropriate punctuation in this context. A colon is typically used to signal that a list or explanation follows, making it the suitable choice here. Choices B, C, and D either use a comma, semi-colon, or dash incorrectly to introduce the list, deviating from the standard punctuation rule for listing items. Therefore, they are incorrect in the context of this sentence.

Correct Answer: D

Rationale: The correct answer is D. Parentheses are used to set off supplementary information (the years of Franz Joseph I's reign) that provides context but does not disrupt the flow of the main sentence. Choice A is incorrect as the purpose of the parentheses in this case is not to offer commentary but to provide additional information. Choice B is incorrect as the parentheses do not modify or qualify the statement before. Choice C is incorrect as the information in the parentheses is not identified as being from another source.

Correct Answer: B

Rationale: In the words proactive, progress, and projecting, 'pro-' is a prefix meaning 'before, forward, or front.' This prefix denotes something happening before or moving forward, as seen in 'progress' and 'projecting,' where it signifies moving ahead or progressing. Therefore, the correct answer is B. Choices A, C, and D are incorrect because 'pro-' is not a suffix, affix, or prefix that means 'good, on top of, or over,' 'after, behind, or in back of,' or 'against, under, or below' respectively. The key is to recognize the meaning of the prefix 'pro-' in the given words and associate it with concepts related to being before or moving forward.
