How did the government try to manage the skyrocketing national debt? by suspending income taxes by lowering interest rates by freezing spending by selling bonds

The correct answer is by selling bonds

Bonds are basically like papers of value where a country sells bonds to people which helps its economy. The people save the bonds and in time when the country is great again they buy the bonds back from people with interest. If people want to support their country they can buy the bonds and help in the short run until the country gets back on its feet.
