1. What does 'mm' stand for in the metric system?

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

2. What does the prefix 'Tera' refer to?

• A. 10^12
• B. 10^9
• C. 10^15
• D. 10^6

Correct answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities. Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.' Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.' Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.' Therefore, the correct answer is A.

3. How many yards are in one mile?

• A. 1760 yards
• B. 1500 yards
• C. 2000 yards
• D. 1800 yards

Correct answer: A

Rationale: The correct answer is A: 1760 yards. There are 1760 yards in one mile. This conversion is a standard unit of measurement in the imperial system. Choice B, 1500 yards, is incorrect as it is not the correct conversion from miles to yards. Choice C, 2000 yards, is also incorrect as it does not represent the accurate conversion. Choice D, 1800 yards, is incorrect as it does not reflect the correct number of yards in a mile according to the established conversion rate.

4. How many milligrams are in 1 gram?

• A. 1 mg
• B. 10 mg
• C. 100 mg
• D. 1,000 mg

Correct answer: D

Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.

5. Which of the following is equal to 0.13 inches?

• A. 0.013 inches
• B. 1.3 inches
• C. 0.13 inches
• D. 13 inches

Correct answer: C

Rationale: The correct answer is C: 0.13 inches. When converting decimals to inches, the value remains the same. Choice A, 0.013 inches, represents a smaller value than 0.13 inches as it has an extra zero. Choice B, 1.3 inches, is incorrect as it is a larger value than 0.13 inches. Choice D, 13 inches, is significantly larger than 0.13 inches, making it an incorrect conversion.
