Correct Answer: C

Rationale: The correct answer is C because when referencing a specific report, publication, or statistic like 'gas prices are up 11% from last month,' a citation is necessary to provide credibility and allow readers to verify the information. Choice A is a general statement about gasoline prices and does not require a citation as it is commonly known information. Choice B is a personal observation and not a direct reference to a specific source that would require a citation. Choice D is an anecdotal experience and does not present verifiable data that necessitates a citation.

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.

Correct Answer: A

Rationale: The sentence is well-placed where it is, as it provides context to the narrative about the individual's preferences. Moving it before the preceding sentence or to the end of the first paragraph would disrupt the flow of information and may confuse the reader. Omitting the sentence would result in a gap in the story, leaving the reader questioning the individual's behavior without a clear explanation. Thus, leaving the sentence where it is now is the best choice for maintaining coherence in the narrative.

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: D

Rationale: The transitional phrase 'As it turns out' adds a reflective tone that matches the surprise at how well the RV worked for the family. Choice A ('NO CHANGE') does not introduce any new information or transition. Choice B ('Not surprisingly, the RV') contradicts the surprise factor mentioned in the sentence. Choice C ('Furthermore, the RV') does not provide a suitable transition given the context of the sentence.
