1. A circle has an area of 121π in². Which of the following is the circumference of the circle in terms of pi (π)?

• A. 11Ï€ in
• B. 22Ï€ in
• C. 44Ï€ in
• D. 5.5Ï€ in

Correct answer: B

Rationale: To find the circumference of the circle, we first need to determine the radius. Given that the area of the circle is 121π in², we use the formula for the area of a circle (A = πr²) to find the radius squared. So, r² = 121, which means the radius (r) is 11 in. The circumference of a circle is calculated using the formula 2πr. Substituting the radius value of 11 in, we get 2π(11) = 22π in. Therefore, the correct answer is 22π in. Choice A (11π in), Choice C (44π in), and Choice D (5.5π in) are incorrect because they do not correctly calculate the circumference based on the given area of the circle.

2. What is the process by which a solid changes directly into a liquid?

• A. Melting
• B. Condensation
• C. Sublimation
• D. Deposition

Correct answer: A

Rationale: The correct answer is A: Melting. Melting is the process through which a solid substance changes directly into a liquid. Choice B, Condensation, is the transition from gas to liquid. Choice C, Sublimation, refers to the direct change from solid to gas. Choice D, Deposition, is the direct transition from gas to solid, not from solid to liquid as in the question.

3. Which of the following best describes the relationship in this set of data?

• A. High positive correlation
• B. Low positive correlation
• C. Low negative correlation
• D. No correlation

Correct answer: B

Rationale: The correct answer is 'B: Low positive correlation.' In a low positive correlation, the variables tend to increase together, but the relationship is not strong. This description fits the data set provided. Choice A, 'High positive correlation,' is incorrect because the correlation is not strong. Choice C, 'Low negative correlation,' is incorrect as the variables are not decreasing together. Choice D, 'No correlation,' is incorrect because there is a relationship between the variables, albeit weak.

4. Select the meaning of the word 'somnambulist' in the sentence based on the context clues: 'If you wake up outside in your pajamas in the middle of the night, you may be a somnambulist.'

• A. Explorer
• B. Magician
• C. Insomniac
• D. Sleepwalker

Correct answer: D

Rationale: The correct answer is 'D: Sleepwalker.' A somnambulist is someone who walks or performs other activities while asleep, commonly known as a sleepwalker. In the given sentence, the context of waking up outside in pajamas in the middle of the night indicates an occurrence associated with sleepwalking. Choice A, 'Explorer,' is incorrect as it does not relate to the behavior described. Choice B, 'Magician,' is not related to the context of sleepwalking. Choice C, 'Insomniac,' refers to a person who has difficulty falling asleep or staying asleep, which is not the meaning conveyed in the sentence. Therefore, 'D: Sleepwalker' is the most appropriate choice based on the context clues provided.

5. What part of speech is the word 'disappointed' in the sentence 'I was disappointed by the outcome'?

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

Correct answer: C

Rationale: In the sentence 'I was disappointed by the outcome,' 'disappointed' is used to describe the subject 'I,' indicating its quality. This function classifies 'disappointed' as an adjective. Adjectives modify nouns or pronouns by giving more information about their attributes. Therefore, the correct answer is 'Adjective.' The other choices are incorrect because: - 'Verb' refers to an action word or a state of being, which 'disappointed' is not performing in this sentence. - 'Noun' represents a person, place, thing, or idea, and 'disappointed' does not serve this function in the given sentence. - 'Adverb' modifies verbs, adjectives, or other adverbs, but 'disappointed' is not modifying any of these in the sentence provided.
