Answer:
1. D. Christians recovered some of the Iberian Peninsula.
2. B. They cared for sick people.
3. C. They were part of a small group who could read.
Step-by-step explanation:
1. D is correct option because larger portion of peninsula (not the whole) was in the hands of Muslims, but Christians managed to take some territories, such as Castile. France had no territories there.
2. B is correct option, because nuns couldn't participate in political life, couldn't educated anyone or participate in public life. That is why other options are false.
3. C is correct because there weren't universities until 11th Century, so monks educated themselves in monasteries, where only a small group of people could read. Education wasn't spread that much in medieval period.
