1. What is 0.025 mg converted to micrograms?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000, not 10000. Therefore, 0.025 mg is equal to 25 mcg. The correct conversion is obtained by recognizing that 1 milligram (mg) is equal to 1000 micrograms (mcg). Choices B, C, and D are incorrect because they do not correctly convert milligrams to micrograms. Choice B is 10 times the correct answer, choice C is 100 times less, and choice D is 100 times less than the correct conversion.

2. How many ounces are in 2 quarts?

• A. 8 ounces
• B. 32 ounces
• C. 16 ounces
• D. 64 ounces

Correct answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart is equal to 32 ounces. Therefore, 2 quarts would be 2 x 32 = 64 ounces. The correct answer is not 16 ounces as stated in the original rationale. The correct answer is 64 ounces, which corresponds to 2 quarts. As a result, 'C: 16 ounces' is incorrect. Options A, B, and D are also incorrect as they do not reflect the accurate conversion from quarts to ounces.

3. What is 0.025 mg in mcg?

• A. 25 mcg
• B. 250 mcg
• C. 2.5 mcg
• D. 0.25 mcg

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in a milligram. Therefore, 0.025 mg x 1000 = 25 mcg. This means that the correct answer is A, 25 mcg. Choice B, 250 mcg, is incorrect because it incorrectly multiplies by 10 instead of 1000. Choice C, 2.5 mcg, is incorrect as it inaccurately divides the value by 10. Choice D, 0.25 mcg, is also incorrect as it divides the value by 100 instead of multiplying by 1000.

4. How many quarts are in 1 gallon?

• A. 2 quarts
• B. 4 quarts
• C. 3 quarts
• D. 1 quart

Correct answer: B

Rationale: The correct answer is B: 4 quarts. There are 4 quarts in 1 gallon. This conversion is based on the fact that 1 gallon is equivalent to 4 quarts. Choice A is incorrect as 2 quarts are half of a gallon, not a whole gallon. Choice C is incorrect as 3 quarts is less than a gallon. Choice D is incorrect as it represents only one quart, whereas the question asks for the quantity in a gallon.

5. What is the term for the amount of space an object occupies?

• A. mass
• B. volume
• C. density
• D. area

Correct answer: B

Rationale: The correct term for the amount of space an object occupies is 'volume.' Volume refers to the three-dimensional space that an object occupies and is measured in cubic units like cubic meters. 'Mass' (Choice A) refers to the amount of matter in an object, 'density' (Choice C) is the mass per unit volume of a substance, and 'area' (Choice D) is the measurement of the extent of a surface.
