The option to rewrite this sentence should clarify, but not change, its meaning. The correct answer: "As we grow older, our thoughts and feelings on faith sometimes change during the holidays," allows the ideas to flow more smoothly without altering the content: each fact is still relayed (the time of year; things that are changing, etc.), but the tone is much clearer. 

The main issue with the underlined portion of the sentence is that "complexing" is not actually a word. The correct answer will appropriately change the word into the best form of "complex" to fit the sentence. To describe the elements best involves making the word into the phrase "more complex."

This sentence demonstrates a comma splice, in which a comma connects two complete sentences. Comma splices are incorrect, as the independent clauses should either remain separate and be treated as complete sentences or be linked by a semicolon or a conjunction. "Coffee can be expensive, but also needing it to stay awake" lacks a subject in the second clause. "Coffee can be expensive; to stay awake" illustrates an incorrect use of a semicolon, as the second clause is not a complete sentence. "Coffee can be expensive, however, the reason I need it is to stay awake" repeats the comma splice of the original sentence. "Being expensive, I need coffee to stay awake" is an example of a dangling modifier, where "being expensive" incorrectly modifies "I" instead of "coffee." Therefore, the correct answer must be "Coffee can be expensive; however, I need it to stay awake," which displays the correct use of a semicolon to connect two complete sentences.

A complete sentence must include a subject and a main verb. Because the original sentence contains two modifying clauses but no main verb, it is actually a sentence fragment. The incorrect answers all contain modifying clauses but lack a main subject-verb relationship. The correct answer therefore must be, "Historians of the colonial Caribbean often focus on the issue of slavery, as its legacy continues to be a major theme in the region." This sentence contains the subject "Historians" and the main verb "focus," and it is therefore a grammatically complete sentence.

In this sentence, the verbs "to fish," "to hike," and "to go" must use parallel structures (the verbs must be in the same tense). The option "fishing, hiking, and going to the beach" is the only one in which all three verbs are in parallel structures, making it the correct choice.

Because the underlined portion of the sentence is an introductory phrase it must be followed by a comma. The incorrect answer choices omit the comma, change the meaning of the sentence, don't agree with the sentence, or are excessively wordy. Thus, because the given sentence separates the introductory phrase with a comma and is grammatically correct, no change is necessary.

The original statement is grammatically incorrect because "audience" and "show" should be plural.  Also, "his audience enjoying the show" makes the sentence into a run-on.  The correct answer is concise and not awkward.  

The sentence as written is actually a fragment, as it does not contain a proper verb. The word "appreciating" in the sentence is a gerund, or a verb form that can function as anoun. The correct answer will use a full verb form, as "Every person in the room appreciated the jokes by the performers" does.

The underlined phrase in the sentence is awkwardly worded, which makes the sentence itself difficult to understand. The "religious texts" contain contradictions, a meaning not conveyed properly by the sentence. "Contradicting themselves" is the clearest, most appropriate choice among the answers.

The underlined phrase is very awkwardly worded, and the use of the past perfect form "have been" is confusing. The phrase needs to be cleaned up for better clarity of meaning. "When they are adults" is the best choice among the answers.
