Several of these questions are opinion, so I can't really help with those, but I can answer the first one.
After World War I, the League of Nations was created to try to help keep the peace and solve problems between nations. The same went for the United Nations after World War II. There were also the treaties that ended the wars. (You'll have to decide whether or not these were actually successful.)
The railroads in Great Britain during the industrial revolution had a positive effect in helping the revolution go on. There were many ways railroads effected the revolution, like making transportation easy, or helping out the economy, but lets just focus on one major effect. Railroads effected the Industrial Revolution by making a high demand for metal, coal, and wood, which made the economy become richer. The reason why railroads effected these is because of the railroads, the price for metal and coal became higher. In order to make railroads, you would need metal and wood, and a lot of people wanted to be in the railroad industry, so people that had lots of metal and wood would sell them for high prices and make profit from it. Because people sold metal and wood for high prices, it helped the economy become richer. Coal was also another thing that was high in value. The reason why coal was high in value is because in order for a train to function during the revolution, it needed coal, and coal was the main thing that made a train move. People that had coal would sell them for high prices because a lot of people will demand for it, meaning that a lot of people would need it, and made profit from coal. This also was another factor that made the economy richer.
Answer: It is B. The explanation is down there.
Explanation: Since half of the economy of the 8 countries were successful in earning money, they have created an industrialized country for themselves. Meanwhile, the other 4 unsuccessful countries have lost money and created an unindustrialized country for themselves.
