Question

how did the us government raise money to finance the war?
by holding scrap drives
by rationing scarce goods
by selling war bonds

Explanation:

To finance wars, the US government historically sold war bonds (like Liberty Bonds in WWI, War Savings Bonds in WWII) to raise funds from citizens. Scrap drives (collecting materials) and rationing (allocating goods) are for resource management, not direct war financing. So the correct method is selling war bonds.

Answer:

By selling war bonds
