Which is true about the “lost generation”? they thought life was too short not to have fun. they tried to win favor with the wealthy but became poor. they did not think the lifestyle of the 1920s was desirable. they were trying to find a country that would welcome them.

The correct answer is - they did not think the lifestyle of the 1920s was desirable. The term "lost generation" refers to a group of writers who were at their peak after the WWI, and came into this post-war world which was completely different to them. They couldn't see any good things in it, which is why they often wrote about how a dreadful era that was to be alive.
