1. Which term is descriptive of a small child just learning to walk?

• A. Obese
• B. Toddler
• C. Geriatric
• D. Hale

Correct answer: B

Rationale: The correct answer is 'B: Toddler.' A toddler is a young child typically between the ages of one and three who is just learning to walk. 'Obese' (choice A) refers to excess body fat, 'Geriatric' (choice C) pertains to elderly individuals, and 'Hale' (choice D) means strong and healthy, none of which are descriptive of a small child learning to walk.

2. A treatment that is detrimental is ___________.

• A. risk-free
• B. destructive
• C. agonizing
• D. effective

Correct answer: B

Rationale: A treatment that is detrimental is considered destructive because it causes harm or damage rather than benefiting the individual. In this context, 'detrimental' implies that the treatment has negative effects and is harmful rather than helpful. Choices A, C, and D are incorrect because a detrimental treatment is not risk-free, agonizing, or effective; instead, it is harmful and damaging.

3. Which is not a step in the water cycle?

• A. Condensation
• B. Transpiration
• C. Nitrification
• D. Absorption

Correct answer: C

Rationale: Nitrification is a biological process in the nitrogen cycle where ammonia is converted into nitrites and then nitrates by bacteria. It is not a step in the water cycle. The water cycle involves processes like evaporation, condensation, precipitation, and transpiration that are related to the movement and transformation of water in the environment. Choices A, B, and D are all part of the water cycle: condensation is the process where water vapor turns into liquid water, transpiration is the release of water vapor by plants, and absorption refers to the process of water being taken in by soil or other materials.

4. What is 20% of 2?

• A. 0.4
• B. 0.2
• C. 0.3
• D. 0.1

Correct answer: A

Rationale: To find 20% of a number, you multiply the number by 0.20. In this case, 0.20 * 2 = 0.4. Therefore, 0.4 is 20% of 2. Choice A (0.4) is correct. Choice B (0.2) is incorrect because it represents 10% of 2, not 20%. Choice C (0.3) is incorrect as it is not the result of calculating 20% of 2. Choice D (0.1) is incorrect as it represents 5% of 2, not 20%.

5. Which part of the brain controls breathing and heart rate?

• A. Cerebrum
• B. Medulla oblongata
• C. Cerebellum
• D. Hypothalamus

Correct answer: B

Rationale: The medulla oblongata, located in the brainstem, plays a crucial role in controlling vital functions such as breathing, heart rate, and blood pressure. It serves as the control center for automatic functions necessary for survival, making it the correct choice in this scenario. The cerebrum is responsible for higher brain functions like thinking and voluntary movements, so it does not control basic physiological functions like breathing and heart rate. The cerebellum is mainly involved in coordination and balance, while the hypothalamus regulates body temperature, hunger, and thirst, but not specifically breathing and heart rate.
