01 If a person sells an old mobile phone to another person, why does the main sale amount not enter current GDP?
Answer and explanation
Correct answer: B. Because the old phone is not current-year production
Explanation: GDP measures the market value of goods and services newly produced during a specified period. When an old mobile phone is resold, the phone itself was produced and counted when it was originally manufactured, so counting its full resale price again would double-count the same production. The sale may involve a current brokerage or repair service, but the old asset’s main sale value is excluded. Hence, option B is correct.
