A: 50 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 50 grams. B: 500 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 500 grams. D: 5 grams - Incorrect. 5 kilograms is equal to 5000 grams, not 5 grams.

The French Academy of Sciences proposed the system to standardize measurements for scientific and commercial purposes. France played a significant role in promoting and spreading the use of the metric system worldwide. Germany (A), Italy (C), and Spain (D) did not have a direct role in the development of the metric system.

Correct Answer: B

Rationale: The correct answer is B: 2 cups in one pint. A pint is equivalent to 2 cups in the US customary system of measurement. This conversion is based on the fact that 1 pint is equal to 16 fluid ounces, and 1 cup is equal to 8 fluid ounces. Therefore, 16 fluid ounces (1 pint) divided by 8 fluid ounces (1 cup) equals 2 cups. The other choices are incorrect because they do not accurately represent the conversion between pints and cups. Choice A (1 cup) is incorrect as it does not match the conversion factor. Choices C (3 cups) and D (4 cups) are incorrect as they provide values that do not align with the correct measurement relationship between pints and cups.

Correct Answer: B

Choice A (60 ml) is incorrect as it is 10 times less. Choice C (6 ml) is incorrect as it is 100 times less. Choice D (6000 ml) is incorrect as it is 10 times more.
