1. Which conversion is accurate?

• A. 1 inch = 2.5 cm
• B. 1 meter = 39.37 inches
• C. 1 liter = 1.057 quarts
• D. 1 gram = 100 milligrams

Correct answer: C

Rationale: The correct answer is C: '1 liter = 1.057 quarts.' This conversion is accurate as it reflects the precise relationship between liters and quarts, where 1 liter is slightly more than a quart. Choice A is incorrect because 1 inch is approximately equal to 2.54 cm, not 2.5 cm. Choice B is incorrect as 1 meter is equivalent to approximately 39.37 inches, not exactly. Choice D is also inaccurate as 1 gram is equal to 1000 milligrams, not 100 milligrams.

2. What does 'g' stand for in the metric system?

• A. gram
• B. grain
• C. goose
• D. grammage

Correct answer: A

Rationale: In the metric system, 'g' stands for gram, which is the base unit for mass. Choice B, 'grain,' is a measurement unit in the imperial system and not the metric system. Choice C, 'goose,' is unrelated to the metric system. Choice D, 'grammage,' is a term used to describe the weight of paper or fabric, not a unit in the metric system.

3. Convert 100 grams to kilograms.

• A. 0.1 kg
• B. 1 kg
• C. 10 kg
• D. 0.01 kg

Correct answer: A

Rationale: To convert grams to kilograms, you need to divide by 1000 since there are 1000 grams in a kilogram. So, 100 grams divided by 1000 equals 0.1 kilograms, making choice A the correct answer. Choices B, C, and D are incorrect because they do not involve the correct conversion factor or calculation. Choice B of 1 kg is the equivalent of 1000 grams, which is 10 times the given value of 100 grams, making it too large. Choice C of 10 kg is 100 times the given value, and choice D of 0.01 kg is 10 times smaller than the correct conversion.

4. What is the formula for calculating the volume of a solid object?

• A. V = W/L
• B. V = L x W x H
• C. V = W/H
• D. V = L/W

Correct answer: B

Rationale: The correct formula for calculating the volume of a solid object is V = L x W x H, where L represents the length, W represents the width, and H represents the height. Choice A (V = W/L) is incorrect as it represents a division operation, not multiplication. Choice C (V = W/H) is incorrect as it does not account for the width and height. Choice D (V = L/W) is incorrect as it represents the inverse operation of what is needed to calculate volume.

5. Where was the metric system developed?

• A. Germany
• B. France
• C. Italy
• D. Spain

Correct answer: B

Rationale: The metric system was developed in France during the 1790s as a standardized system of measurement. This choice is correct because the metric system originated in France. Germany, Italy, and Spain did not play a role in the development of the metric system, making choices A, C, and D incorrect.
