1. Solve for x: 3x + 2 = 14

• A. x = 4
• B. x = 2
• C. x = 6
• D. x = 3

Correct answer: A

Rationale: To solve the equation 3x + 2 = 14, first, subtract 2 from both sides to isolate 3x: 3x = 12. Then, divide by 3 to solve for x: x = 4. Therefore, the correct answer is A, x = 4. Choice B, x = 2, is incorrect because it does not satisfy the equation. Choice C, x = 6, is incorrect as well since it does not satisfy the equation. Choice D, x = 3, is also incorrect as it does not satisfy the given equation.

2. How many grams are in 7 kilograms?

• A. 7000 grams
• B. 70 grams
• C. 700 grams
• D. 70,000 grams

Correct answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 7 kilograms is equal to 7 x 1,000 = 7,000 grams. The correct answer is 7000 grams. Choice B (70 grams) is incorrect as it represents the conversion of 7 kilograms to grams without considering the correct multiplier. Choice C (700 grams) is incorrect as it is a tenth of the correct conversion. Choice D (70,000 grams) is incorrect as it is ten times the correct conversion.

3. As a vehicle positioned at the peak of a hill rolls downhill, its potential energy transforms into:

• A. Thermal energy
• B. Neither thermal nor kinetic energy
• C. A combination of thermal and kinetic energy
• D. Kinetic energy

Correct answer: D

Rationale: The correct answer is D: Kinetic energy. Potential energy is converted into kinetic energy as the vehicle moves downhill. Kinetic energy is the energy possessed by a moving object. Thermal energy is not produced in this scenario because the energy transformation is mainly from potential to kinetic energy, not involving heat generation. Choices A, B, and C are incorrect because the primary energy transformation in this scenario is from potential to kinetic energy, not involving thermal energy.

4. The passage mentions all of the following claims for the health benefits of super foods EXCEPT ___________.

• A. lowering cholesterol
• B. stabilizing insulin levels
• C. building muscle mass
• D. reducing blood pressure

Correct answer: C

Rationale: The passage discusses various health benefits of superfoods, such as lowering cholesterol, stabilizing insulin levels, and reducing blood pressure. However, it does not mention anything about building muscle mass, making C the correct choice as it identifies the claim that is not supported by the passage.

5. Which vitamin is necessary for blood clotting?

• A. Vitamin D
• B. Vitamin K
• C. Vitamin C
• D. Vitamin B12

Correct answer: B

Rationale: Vitamin K is essential for the synthesis of proteins involved in blood clotting. These proteins help in the coagulation process, ensuring that wounds can heal properly by preventing excessive bleeding. Without sufficient Vitamin K, the blood clotting process may be impaired, leading to potential health risks. Vitamin D is important for bone health, Vitamin C is essential for the immune system and collagen production, and Vitamin B12 plays a role in red blood cell production and nerve function, but they are not directly involved in the blood clotting process.
