1. What is the fundamental unit of life?

• A. Atom
• B. Cell
• C. Tissue
• D. Organ

Correct answer: B

Rationale: The correct answer is 'B: Cell.' Cells are indeed the fundamental unit of life as they are responsible for all living functions, including growth, reproduction, and maintaining homeostasis. While atoms are the basic building blocks of matter, cells are the smallest structural and functional unit of living organisms. Choices C and D, tissue and organ respectively, are composed of multiple cells working together and are not considered the basic unit of life.

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. Another word for UNDER OBSERVATION is?

• A. Cognition
• B. Isolation
• C. Surveillance
• D. Assessment

Correct answer: C

Rationale: Another word for UNDER OBSERVATION is surveillance. Surveillance refers to the close observation of a person, group, or place, especially in a secret or discreet manner. It involves monitoring and watching over someone or something closely for a specific purpose. Therefore, the word 'surveillance' is the most suitable synonym for under observation in this context. Choice A, 'Cognition,' refers to the mental process of acquiring knowledge and understanding through thoughts, experience, and the senses; it is not synonymous with under observation. Choice B, 'Isolation,' means the process or fact of isolating or being isolated, which does not convey the idea of close monitoring. Choice D, 'Assessment,' involves evaluating or judging the nature, ability, or quality of something, which is different from the act of observing closely.

4. What percent of 36 is 9?

• A. 25%
• B. 20%
• C. 15%
• D. 10%

Correct answer: D

Rationale: To find out what percent 9 is of 36, divide 9 by 36 and multiply by 100 to convert it to a percentage. So, (9/36) * 100 = 25%. This indicates that 9 is 25% of 36, not 10%. Choice A, 25%, is the result of calculating what percent 36 is of 9, not the other way around. Choices B and C are incorrect as they do not align with the calculated percentage.

5. What is the main idea of the passage?

• A. Senior citizens need to increase their calcium and vitamin D intake.
• B. The food pyramid was revised to reflect the needs of seniors.
• C. Physical activity is a new addition to the food pyramid.
• D. The revised food pyramid looks more like a food square.

Correct answer: B

Rationale: The passage discusses the revision of the food pyramid specifically to address the unique dietary needs of seniors. It emphasizes how the changes were made based on ongoing research and analysis, indicating a broader focus on senior nutrition rather than just individual nutrients or exercise. Thus, option B captures the essence of the passage as it succinctly summarizes the main idea.
