1. Which of the following is the meaning of the word bestowed as it is used in the passage?

• A. purchased
• B. forgotten
• C. accepted
• D. given

Correct answer: D

Rationale: The word 'bestowed' in this context means to be given or presented with something. In the passage, it is mentioned that good powers were bestowed upon different animals by Epimetheus. This implies that these powers were given or presented to the animals. Choice A, 'purchased,' does not align with the context of the passage as the animals did not buy or acquire these powers. Choice B, 'forgotten,' is incorrect as it does not relate to the act of giving. Choice C, 'accepted,' is also incorrect as it implies that the animals willingly received these powers, which is not the case in the passage. Therefore, the correct answer is 'D: given.'

2. What does the number of protons in the nucleus of an atom determine?

• A. Mass number
• B. Atomic number
• C. Isotope
• D. Valence electron count

Correct answer: B

Rationale: The number of protons in the nucleus of an atom is referred to as the atomic number. This atomic number is crucial as it uniquely identifies an element and determines its position on the periodic table. The mass number, on the other hand, represents the sum of protons and neutrons in an atom's nucleus. Isotopes are variants of elements with the same number of protons but differing numbers of neutrons. Valence electron count pertains to the number of electrons in the outermost energy level of an atom, which influences its chemical behavior.

3. What is the protective fluid that surrounds the brain and spinal cord?

• A. Blood
• B. Cerebrospinal fluid
• C. Myelin sheath
• D. Insulin

Correct answer: B

Rationale: Cerebrospinal fluid is the protective fluid that surrounds the brain and spinal cord. It acts as a cushion to protect these vital organs from injury and provides nutrients and removes waste products. Blood, myelin sheath, and insulin do not serve as the protective fluid surrounding the brain and spinal cord. Blood carries nutrients and oxygen to cells, myelin sheath is a protective covering of nerve fibers, and insulin is a hormone involved in regulating blood sugar levels.

4. Which of the following best describes the statement 'This flower is dead; someone must have forgotten to water it'?

• A. A classification
• B. An observation
• C. An inference
• D. A collection

Correct answer: C

Rationale: The correct answer is 'C: An inference.' An inference is a conclusion reached based on evidence and reasoning. In this statement, the conclusion that someone must have forgotten to water the flower is drawn from the evidence that the flower is dead. Choice A, 'A classification,' is incorrect because the statement does not involve categorizing or grouping. Choice B, 'An observation,' is incorrect as the statement goes beyond just stating a fact and makes a conclusion. Choice D, 'A collection,' is unrelated to the process of drawing a conclusion based on the given evidence.

5. What is the primary function of the liver related to digestion?

• A. Produces bile
• B. Stores bile
• C. Converts waste ammonia into urea
• D. Filters and detoxifies digestion byproducts

Correct answer: D

Rationale: The primary function of the liver related to digestion is to filter and detoxify byproducts of digestion, including toxins and metabolic waste products. While the liver does produce bile and convert waste ammonia into urea, these functions are not directly related to digestion. Storing bile is mainly done by the gallbladder, not the liver.
