Expenditures on federal highways.
Answer: Option 4.
Step-by-step explanation:
GDP does not account for off-the-books activities, such as babysitting, which add value to the economy but are not reported to the government. GDP doesn't take into account the loss of enjoyment people incur when scenic land is converted to commercial use. All of these, though important in measuring the true quality of life within a country, would be far too difficult to measure accurately.
But the expenditure that the government will make on the construction of the highways of the country will be accounted for.
