1. Simplify the following expression: 7 + 16 - (5 + 6 × 3) - 10 × 2

• A. -42

2. What is the general formula for an alkyl halide?

• A. Câ‚™Hâ‚‚â‚™
• B. Câ‚™H₂ₙ₊₂
• C. Câ‚™H₂ₙ₊₁X
• D. Câ‚™Hâ‚‚â‚™O

Correct answer: C

Rationale: The correct answer is option C, 'CₙH₂ₙ₊₁X.' This is the general formula for an alkyl halide, where X represents a halogen atom (such as fluorine, chlorine, bromine, or iodine), and the hydrocarbon chain is represented by CₙH₂ₙ₊₁. Option A, 'CₙH₂ₙ,' is incorrect because it does not account for the presence of a halogen atom. Option B, 'CₙH₂ₙ₊₂,' is incorrect as it represents an alkene, not an alkyl halide. Option D, 'CₙH₂ₙO,' is also incorrect as it suggests the presence of oxygen, which is not characteristic of alkyl halides.

3. At last night’s company function, in honor of Mr. Robertson’s retirement, several employees spoke kindly about his career achievements. In the preceding sentence, what part of speech is the word function?

• A. Adjective
• B. Adverb
• C. Verb
• D. Noun

Correct answer: D

Rationale: In the sentence provided, the word 'function' is used as a noun to refer to an event or gathering. Nouns name people, places, things, or ideas, and in this case, 'function' is a thing (an event), so it functions as a noun. Adjectives describe nouns, adverbs modify verbs, and verbs express actions or states, none of which apply to the word 'function' in the sentence. Therefore, the correct answer is 'D: Noun.' Choices 'A: Adjective,' 'B: Adverb,' and 'C: Verb' are incorrect because 'function' in this context isn't being used to describe, modify, or express an action; it is naming an event.

4. What does the prefix 'centi' mean?

• A. 0.1
• B. 0.01
• C. 0.001
• D. 1

Correct answer: B

Rationale: The prefix 'centi' means 0.01, which is one-hundredth of the base unit. For example, 1 centimeter is equal to 0.01 meters. Choice A (0.1) is incorrect as it represents 'deci,' which means one-tenth. Choice C (0.001) is incorrect as it represents 'milli,' which means one-thousandth. Choice D (1) is incorrect as it is not a valid interpretation of the prefix 'centi.' Therefore, the correct answer is B.

5. Jorgen learns that Eratosthenes was fascinated by the story of the Trojan War and attempted to determine the exact dates when this event occurred. Unfamiliar with the story of the fall of Troy, Jorgen decides to look into writings such as The Iliad and The Odyssey by Homer. To which section of the library should Jorgen go to locate these works?

• A. 100
• B. 200
• C. 700
• D. 800

Correct answer: D

Rationale: Section 800 features works of literature, making it the best place for Jorgen to find The Iliad and The Odyssey. While the philosophy and psychology section (100) might contain references to these works, Jorgen would still have to go to the literature section to obtain the works themselves, as they are literary works. Similarly, the religion section (200) and the arts and recreation section (700) are not where these specific literary works would be located.
