Question

which of these would most likely positively affect a nations gdp?

an increase in the number of non - market sales

a steady growth of that nations underground economy

a government - managed restructuring of the airline industry

a government contract with a large private firm for road construction

Explanation:

GDP measures market value of final goods/services produced. Non-market sales (unrecorded, no market transaction) and underground economy (unreported) don’t count in official GDP. Government restructuring may not directly add production. A road construction contract is a market transaction for a final good, directly contributing to GDP.

Answer:

a government contract with a large private firm for road construction
