1. A caterpillar starts moving at a rate of 14 in/hr. After 15 minutes, it is moving at a rate of 20 in/hr. What is the caterpillar’s rate of acceleration?

• A. 6 in/hr²
• B. 12 in/hr²
• C. 24 in/hr²
• D. 280 in/hr²

Correct answer: C

Rationale: Acceleration is the change in velocity over time. The change in velocity for the caterpillar is 20 in/hr - 14 in/hr = 6 in/hr. Since this change occurred over 15 minutes (or 0.25 hours), the acceleration can be calculated as (6 in/hr) / (0.25 hr) = 24 in/hr². Therefore, the caterpillar's rate of acceleration is 24 in/hr², which corresponds to choice C. Choice A, 6 in/hr², is incorrect as it does not account for the time factor and the correct calculation. Choice B, 12 in/hr², is incorrect as it doubles the correct acceleration value. Choice D, 280 in/hr², is significantly higher than the correct value, indicating a calculation error.

2. Choose the two bases that have two carbon rings:

• A. Adenine
• B. Cytosine
• C. Thymine
• D. Guanine

Correct answer: A

Rationale: Adenine and guanine have two carbon rings and are known as purines. These bases are found in nucleic acids such as DNA and RNA. Adenine (option A) and guanine (option D) are the correct choices as they both have two carbon rings in their molecular structure. Cytosine (option B) and thymine (option C) have a single carbon ring each, making them incorrect choices for bases with two carbon rings.

3. What does 'Ongoing' mean?

• A. Ended
• B. Continuous
• C. Delayed
• D. Occasional

Correct answer: B

Rationale: The correct answer is 'B: Continuous.' 'Ongoing' is used to describe something that is currently happening or continuing without interruption. Choices A, C, and D are incorrect because 'Ended,' 'Delayed,' and 'Occasional' do not reflect the continuous nature associated with 'Ongoing.'

4. Select the meaning of the word 'residual' in the sentence. Something that remains is referred to as __________.

• A. Resident
• B. Residual
• C. Resistance
• D. Resin

Correct answer: B

Rationale: The correct answer is 'B: Residual.' In the given sentence, 'residual' is used to describe something that is left or remaining. 'Residual' fits the context perfectly as it aligns with the definition of what remains. The other choices are incorrect: A) 'Resident' refers to a person living in a specific place, C) 'Resistance' is the act of opposing or withstanding something, and D) 'Resin' is a sticky substance produced by plants.

5. What is the meaning of the word touted as used in the first paragraph about Aromatherapy?

• A. Revealed.
• B. Glorified.
• C. Overcome.
• D. Deceived.

Correct answer: B

Rationale: "Touted" in this passage means glorified or praised, indicating how aromatherapy has been widely promoted as beneficial. The context implies that while it is marketed positively, recent studies have called its effectiveness into question. Other choices do not capture this promotional aspect accurately, making B the best fit.
