1. Why might certain young people be underweight?

• A. They are growing in height faster than they are gaining weight.
• B. They eat little protein and too much fat and sugar.
• C. They eat several meals a day and fail to exercise enough.
• D. They seldom eat a meal that contains foods from all food groups.

Correct answer: A

Rationale: Certain young people might be underweight because they are growing in height faster than they are gaining weight. During periods of rapid growth, the body's energy requirements are primarily directed towards height growth rather than weight gain, resulting in some individuals being underweight despite consuming sufficient calories. Choice B is incorrect because the question focuses on reasons related to growth rather than diet composition. Choice C is incorrect as it suggests overeating rather than the specific growth-related issue of height surpassing weight gain. Choice D is incorrect as it addresses nutritional variety rather than the growth dynamics affecting weight.

2. Which statement is true of a saturated solution?

• A. It has more solute than can dissolve in the solvent.
• B. It has less solute that can dissolve in the solvent.
• C. It has the maximum concentration of the solute dissolved in the solvent.
• D. It contains a precipitate that lowers the concentration of the solute in the solvent.

Correct answer: C

Rationale: A saturated solution contains the maximum concentration of solute that can be dissolved in a specific amount of solvent at a particular temperature. Once a solution is saturated, adding more solute will not increase its concentration since the excess solute will not dissolve and will instead form a precipitate, indicating that the solution is at its maximum capacity. Choices A, B, and D are incorrect because a saturated solution has reached its limit in dissolving solute, so it cannot contain more solute than it can dissolve (choice A), less solute than it can dissolve (choice B), or a precipitate that lowers the concentration of the solute in the solvent (choice D).

3. Multiply: 6 × 0.06 =

• A. 0.0036
• B. 0.036
• C. 0.36
• D. 3.6

Correct answer: C

Rationale: When multiplying 6 by 0.06, you can treat 0.06 as 6 hundredths. So, 6 × 0.06 is equivalent to 6 × 6 hundredths, which equals 0.36. The correct answer is 0.36. Choice A (0.0036) is incorrect because it represents 6 multiplied by 0.0006, not 0.06. Choice B (0.036) is incorrect as it represents 6 multiplied by 0.06 without considering the position of the decimal point. Choice D (3.6) is incorrect as it represents 6 multiplied by 6, not by 0.06.

4. Choose the meaning of the word 'affected' in the following sentence: 'Apply a thin film of cream to the affected area once or twice a day depending on the acuteness of the condition.'

• A. Involved
• B. Diseased
• C. Assumed
• D. Perceived

Correct answer: B

Rationale: In the context of the sentence, 'affected' is used to describe the area that requires the application of cream. It refers to a part of the body that is diseased or suffering from some ailment. Therefore, the correct meaning of 'affected' in this context is 'Diseased.' Choice A, 'Involved,' does not accurately capture the medical context of the sentence. Choice C, 'Assumed,' is not relevant to the physical condition described in the sentence. Choice D, 'Perceived,' does not convey the idea of a physical ailment, making it incorrect. The most appropriate interpretation is 'Diseased,' as it aligns with the context of applying cream to a specific area due to a health issue.

5. How many meters are in 2 kilometers?

• A. 100 meters
• B. 200 meters
• C. 2000 meters
• D. 3000 meters

Correct answer: C

Rationale: 1 kilometer equals 1,000 meters. Therefore, 2 kilometers equals 2,000 meters. Choice A, 100 meters, is incorrect as it represents only 1/10th of a kilometer. Choice B, 200 meters, is incorrect as it represents only 1/5th of a kilometer. Choice D, 3000 meters, is incorrect as it miscalculates the conversion from kilometers to meters.
