what happens when the countries with a negative trade balance can't afford to import goods anymore? who does it hurt?

It Hurts the buyers and traders when they can't afford for good items maybe food it depends what they are trading. If they are Negative they either have to trade other traders or they need to buy more goods to trade and sell for possibility better items kind of like scamming like how Railroad Companies would scam farmers and lie about the price to get more money.

It would most likely affect the traders the most

And if they have any buyers it would affect them as well because the traders are negative. (This is all based off what I learn in my classes)

peasants’ war, (1524–25) peasant uprising in germany inspired by changes brought by the reformation, peasants in western and southern germany invoked   divine law to demand agrarian rights and freedom from oppression by nobles and landlords. as the uprising spread, some peasant groups organized armies. although the revolt was supported huldrych zwingli and thomas müntzerits condemnation by martain luther contributed to its defeat, principally by the army of the swabian league. some 100,000 peasants were killed. reprisals and increased restrictions discouraged further attempts to improve the peasants’ plight.

i think it would be " a" i might be wrong tho

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
