1. Select the meaning of the word 'exogenous' in the sentence: 'Exogenous factors will affect the patient’s well-being.'

• A. Produced outside the body
• B. Produced within the body
• C. Produced by the kidneys
• D. Hereditary

Correct answer: A

Rationale: The correct answer is A: 'Produced outside the body.' In the given sentence, 'exogenous' is used to refer to factors that originate externally, such as environmental influences. Choice B, 'Produced within the body,' is incorrect as it describes endogenous factors. Choice C, 'Produced by the kidneys,' is incorrect as it specifies a specific organ rather than the general concept of external origin. Choice D, 'Hereditary,' is incorrect as it relates to genetic inheritance, which is not the meaning of 'exogenous.'

2. Finishing isn't as important as answering correctly.

• A. Quick
• B. As quick
• C. So quickist
• D. Quickly

Correct answer: D

Rationale: In this sentence, 'quickly' is the correct adverb form that should be used to modify the verb 'answering.' 'Quickly' is the adverb form needed here to describe how the action is performed. Choices A, B, and C are incorrect because they do not provide the appropriate adverb form required in the sentence.

3. When a junked car is compacted, which statement is true?

• A. Its mass increases.
• B. Its mass decreases.
• C. Its density increases.
• D. Its density decreases.

Correct answer: C

Rationale: When a junked car is compacted, its volume decreases while its mass remains the same. As a result, the car's density increases because density is mass divided by volume. Choice A is incorrect because the mass of the car remains the same. Choice B is incorrect because the mass does not decrease. Choice D is incorrect because the density increases as the volume decreases, not decreases.

4. What is the meaning of plastic?

• A. Mechanical
• B. Durable
• C. Authentic
• D. Flexible

Correct answer: D

Rationale: The correct answer is D: Flexible. Plastic is a material that can be easily molded or shaped, known for its flexibility. It can bend and stretch without breaking, making it versatile and durable. Choices A, B, and C are incorrect because plastic is not primarily associated with being mechanical, authentic, or durable, but rather with its ability to be shaped and its flexibility.

5. Whose energy efficiency is greater?

• A. Herbivore
• B. Carnivore
• C. Omnivore
• D. Decomposer

Correct answer: D

Rationale: Decomposers have the greatest efficiency of energy among the given options. Decomposers break down organic matter, such as dead plants and animals, into simpler substances through the process of decomposition. This breakdown process results in the release of nutrients back into the ecosystem, making energy more readily available for other organisms to use. In contrast, herbivores, carnivores, and omnivores all derive their energy from the consumption of other living organisms, making their energy efficiency lower than that of decomposers. Herbivores consume plants for energy, which involves energy loss due to inefficiencies in converting plant matter into usable energy. Carnivores consume herbivores or other carnivores, leading to further energy loss through each trophic level. Omnivores consume both plant and animal matter, but their energy efficiency is still lower than decomposers because of the energy loss associated with consuming living organisms. Decomposers play a crucial role in recycling nutrients and energy in ecosystems, making them highly efficient in the utilization of energy.
