1. The teacher shared several apothegms with the class, hoping that the short, wise sayings would inspire thoughtful discussions.

• A. instructions
• B. questions
• C. sayings
• D. lectures

Correct answer: C

Rationale: In this context, apothegms refers to short, wise sayings meant to convey wisdom or provoke thought. Apothegms are concise and insightful, serving as nuggets of wisdom. The term 'instructions' implies a set of directions or guidelines, not reflective of the nature of apothegms. 'Questions' are queries seeking information or answers, not synonymous with wise sayings. 'Lectures' are formal presentations or speeches, which are more extensive and detailed compared to the concise nature of apothegms.

2. Which hormone is responsible for regulating sleep-wake cycles and is influenced by light exposure?

• A. Melatonin
• B. Cortisol
• C. Estrogen
• D. Glucagon

Correct answer: A

Rationale: The correct answer is A: Melatonin. Melatonin is the hormone responsible for regulating sleep-wake cycles, also known as the circadian rhythm. Its production is influenced by light exposure, with levels increasing in the evening in response to darkness, signaling the body that it is time to sleep. Choice B, cortisol, is a stress hormone and does not directly regulate sleep-wake cycles. Choice C, estrogen, is a sex hormone and is not primarily involved in regulating sleep. Choice D, glucagon, is a hormone that increases blood glucose levels and is not related to sleep-wake cycles.

3. What part of speech is the word 'growing' in the sentence: 'He felt a growing sense of unease'?

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

Correct answer: B

Rationale: The word 'growing' in the sentence 'He felt a growing sense of unease' is functioning as an adjective. It describes the sense of unease, indicating a characteristic of the sense rather than an action (verb), a person, place, thing, or idea (noun), or modifying a verb, an adjective, or another adverb (adverb). Therefore, 'growing' is an adjective in this context.

4. Which sentence uses the correlative conjunction 'either/or' correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option A uses the correlative conjunction 'either/or' correctly by presenting two exclusive options. The structure 'either...or' is used to show a choice between two alternatives, and in this sentence, it clearly presents the options of coming to the party or staying home. Choice B incorrectly separates the options with a comma after 'either,' disrupting the correlative conjunction pair. Choice C uses 'whether' instead of 'either/or,' which changes the meaning and structure. Choice D uses 'either' incorrectly, as it should be followed by 'or' to form the correlative pair.

5. Complete the following equation: 2 + (2)(2) - 2 ÷ 2 = ?

• A. 5
• B. 3
• C. 2
• D. 1

Correct answer: A

Rationale: To solve the equation, follow the order of operations (PEMDAS/BODMAS): Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). 1. Calculate inside the parentheses first: (2)(2) = 4. 2. Then, perform multiplication and division: 2 + 4 - 1 = 6 - 1 = 5. Therefore, the correct answer is 5. Choice B (3) is incorrect because multiplication is done before subtraction. Choices C (2) and D (1) are incorrect as they do not follow the correct order of operations to solve the equation.
