We rejoiced as 'hackers.' Which of the following is the best revision of the sentence?

Correct Answer: C

Rationale: Option C is the best revision as it provides clarity and context to the sentence. It conveys the idea that the individuals rejoiced after successfully finding a creative solution to a persistent technological issue. Choice A is incorrect as it leaves the sentence unchanged without adding any context. Choice B introduces the phrase 'nagging technology problem,' which alters the original meaning and is not as concise as the correct answer. Choice D alters the sentence structure and does not effectively convey the intended meaning of rejoicing after finding a solution.

Correct Answer: C

Rationale: Option C correctly punctuates the sentence by placing commas after 'Chicago' and 'Illinois' to separate the location details and inserting a comma before 'in 1948' to separate the location from the date. This creates a clear and grammatically correct sentence. Choices A, B, and D incorrectly place the commas, leading to confusion or incorrect grouping of the location and date information.

Correct Answer: B

Rationale: Option B provides relevant context by specifying that the BPP was another activist group. This clarification helps to establish a parallel between the BPP and the NAACP in terms of their function and purpose. Choice C is incorrect as the number of members is not the key point being compared in the sentence. Choice D is incorrect as it introduces an unrelated comparison involving schools, which is not relevant to the context provided in the sentence.

Correct Answer: C

Rationale: Option C, 'enabled him to quickly rise,' is the correct choice. The sentence is referring to a past action, so the verb should be in the past tense. 'Enabled' is the correct past tense form of 'enable' in this context. Choice A ('NO CHANGE') is incorrect because it does not match the past tense required by the sentence. Option B ('are enabling him to quickly rise') is incorrect as it uses the present continuous tense, which is not suitable for the past action described. Choice D ('will enable him to quickly rise') is incorrect as it implies a future action, which is not consistent with the context of the sentence.

Correct Answer: A

Rationale: All the words in the sentence are spelled correctly, including 'achievement.' There is no misspelling present. 'Greatest,' 'achievement,' and 'leader' are all spelled correctly. Option A is correct as there is no misspelled word in the sentence. Choices B, C, and D are wrong because they are correctly spelled words in the context of the sentence.
