Answer:
D. Western Europe was more rural, less literate, and had more limited trade.
Step-by-step explanation:
After the fall of the Roman Empire, Western Europe entered a period of economic decline that lasted for almost a thousand years, and that had profound political and social consequences.
The political integration that had been common under the Roman Empire for 4 centuries collapsed, and countless states emerged, many of them lasting a few decades, or even years. This political climate caused less economic integration: trade went down to a bare minimum, cities became depopulated, the regions became more ruralized, economies became more local and precarious, poverty rose, and literacy fell as well.
As centuries passed, Western Europe recovered slowly, but it was only until the Late Middle Ages that development levels were similar to those enjoyed during the height of the Roman Empire.
