1. Which of the following reagents can be used to convert a primary alcohol to an alkyl halide?

• A. HI
• B. H2O
• C. NaOH
• D. SOCl2

Correct answer: D

Rationale: SOCl2 (thionyl chloride) is commonly used to convert primary alcohols to alkyl halides through an SN2 mechanism. Thionyl chloride reacts with the alcohol to form an alkyl chloride. HI (hydroiodic acid) is typically used to convert alcohols to alkyl iodides specifically, not alkyl halides in general. H2O (water) and NaOH (sodium hydroxide) are not reagents used for converting alcohols to alkyl halides. Therefore, the correct answer is SOCl2 as it facilitates the conversion of primary alcohols to alkyl halides, unlike the other options provided.

2. Which of the following is the complete subject of the following sentence? All of Shannon’s family and friends helped her to celebrate her 50th birthday at Café Sorrento.

• A. Family and friends
• B. All
• C. All of Shannon’s family and friends
• D. Shannon’s family and friends

Correct answer: C

Rationale: The complete subject in the sentence is 'All of Shannon’s family and friends.' This phrase encompasses the entirety of the group involved in celebrating Shannon’s 50th birthday at Café Sorrento. It includes both her family and friends collectively, highlighting the full extent of individuals who participated in the celebration. The term 'All of Shannon’s family and friends' is essential for providing a comprehensive subject that covers everyone who contributed to making the event special. Choices A, B, and D are incorrect because they do not capture the complete scope of individuals involved in the birthday celebration, unlike choice C which encompasses both Shannon’s family and friends.

3. 4 − 1/(22) + 24 ÷ (8 + 12). Simplify the expression. Which of the following is correct?

• A. 1.39
• B. 2.74
• C. 4.95
• D. 15.28

Correct answer: C

Rationale: First, complete the operations in parentheses: 4 − (1/22) + 24 ÷ 20. Next, simplify the exponents: 4 − (1/22) + 24 ÷ 20 = 4 − (1/4) + 24 ÷ 20. Then, complete multiplication and division operations: 4 − (1/4) + 24 ÷ 20 = 4 − 0.25 + 1.2. Finally, complete addition and subtraction operations: 4 − 0.25 + 1.2 = 4.95. Choice A, 1.39, is incorrect as it does not match the correct calculation. Choice B, 2.74, is incorrect as it is not the result of the given expression. Choice D, 15.28, is incorrect as it is not the correct simplification of the initial expression.

4. What should be done after the soil has been loosened with a tiller or trowel?

• A. Mix fertilizer or compost into loosened soil.
• B. Dig a 4-inch-deep trench.
• C. Cut potatoes into pieces.
• D. Mound soil around the base of the plant.

Correct answer: A

Rationale: After the soil has been loosened with a tiller or trowel, the next step should be to mix fertilizer or compost into the loosened soil. This action is crucial as it provides essential nutrients for plant growth, improves soil fertility, and promotes healthy plant development. Digging a trench, cutting potatoes, or mounding soil around the base of the plant are not tasks typically performed immediately after loosening the soil. Therefore, option A is the correct choice as it aligns with the standard practice of enhancing soil quality before planting.

5. Why does the author repeat the phrase 'I had a dream' throughout the text?

• A. To emphasize the speaker's excitement
• B. To persuade the audience
• C. To demonstrate the speaker's authority
• D. To create a rhythmic effect

Correct answer: A

Rationale: The repetition of 'I had a dream' in the text serves to emphasize the speaker's excitement and vision. By repeating this phrase, the author highlights the importance and impact of the dream, reinforcing the central theme of hope and aspiration. Choices B, C, and D are incorrect because the primary purpose of the repetition is not persuasion, demonstration of authority, or creating a rhythmic effect, but rather to underscore the speaker's emotions and aspirations.
