Answer 1

The person whose brother weighs 40 pounds is from the United States, where the customary unit of weight is pounds. The person whose brother weighs 40 kilograms is from a country where the metric system is used, with kilograms as the unit of weight.

Step-by-step explanation:

In this question, one person's brother weighs 40 pounds and the other person's brother weighs 40 kilograms.

To differentiate between pounds and kilograms, we need to understand their units of measurement. Pounds is a unit of weight commonly used in the United States, while kilograms is a unit of weight used in most other parts of the world.

Therefore, the person whose brother weighs 40 pounds is from the United States, where the customary unit of weight is pounds. The person whose brother weighs 40 kilograms is from a country where the metric system is used, with kilograms as the unit of weight.
