1. What is the meaning of the word supplementation as used in the second paragraph?

• A. Extra
• B. Organization
• C. Attachment
• D. Revision

Correct answer: A

Rationale: The term "supplementation" refers to the addition of nutrients to the diet. In the context of the passage, it highlights the need for seniors to receive extra nutrients such as calcium and vitamin D beyond what they typically consume in their diets. This reflects the understanding that seniors may not get sufficient nutrition solely from their regular meals, supporting option A.

2. Which gland produces melatonin?

• A. Pineal gland
• B. Thyroid gland
• C. Adrenal gland
• D. Pituitary gland

Correct answer: A

Rationale: The correct answer is the Pineal gland. This gland is responsible for producing melatonin, a hormone that helps regulate the sleep-wake cycle. Melatonin production is influenced by exposure to light, with levels typically rising in the evening to promote sleep and falling in the morning to aid wakefulness. The Thyroid gland (choice B) produces hormones that regulate metabolism, the Adrenal gland (choice C) produces hormones like adrenaline and cortisol, and the Pituitary gland (choice D) controls several other glands in the endocrine system.

3. Here are the solubilities of four substances at 0°C, in grams of solute per 100 mL of water. If the temperature increases to 20°C, what would you expect to happen to the solubility figures?

• A. Citric acid and potassium phosphate will decrease; nitrogen and oxygen will increase.
• B. Citric acid and potassium phosphate will increase; nitrogen and oxygen will decrease.
• C. All four figures will increase.
• D. All four figures will decrease.

Correct answer: C

Rationale: Solubility generally tends to increase with temperature for most solid solutes in liquid solvents due to higher kinetic energy leading to better solute-solvent interactions. As the temperature increases from 0°C to 20°C, all four solubility figures are expected to increase. Choice A is incorrect because solubility tends to increase with temperature. Choice B is incorrect as well for the same reason. Choice D is incorrect because the solubility of solid solutes typically increases with temperature.

4. What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

• A. Dispersed.
• B. Incensed.
• C. Painstaking.
• D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

5. Which verb is defined as to bring about; cause to happen; to accomplish; to make?

• A. Affect
• B. Accept
• C. Expect
• D. Effect

Correct answer: D

Rationale: The correct answer is D, 'effect.' The verb 'effect' is defined as to bring about, cause to happen, accomplish, or make. It describes the action of making something happen or producing a result. Choices A, B, and C are incorrect because 'affect' means to influence, 'accept' means to receive willingly, and 'expect' means to anticipate. Therefore, the correct choice is D, 'effect.'
