Answer:
a) there was no evidence to support it
Explanation:
Wegener noticed while looking at the maps that some parts of the continents, especially South America and Africa, seem to match up perfectly. This led him to think that maybe the continents in the past were actually connected, but because of some force they moved apart. He went out public with his hypothesis, but it was largely rejected, and he was laughed at and ridiculed, as the scientists thought that there's no force that can move the continents. Wegener didn't stop there, and he continued to look for clues, and finally managed to find some clues at the topography of the Atlantic Ocean. He noticed that the mid-ocean ridge is the highest, but as you move away from it, the sea mounds are becoming flatter and lower, thus a sign of erosion, and he actually turned out to be right.

The "medieval" buildings are all or mostly reconstructions, from the rubble left behind by German and Soviet bombs and artillery. After that, the communists imposed central planning on top of a destroyed economic base. It's very hard to regenerate money from nothing, and most of what is produced in eastern Europe went into Warsaw Pact defenses and salaries and privileges for the communist party elite, to keep the system of authority in place. After the fall of communism, the post-Cold War governments inherited another kind of economic decay. They instituted "reform" plams to shock the economies into the free market, leaving in their wake massive unemployment and property.</span>
