Answer:
It reveals that many of the evacuated children built strong friendships with their hosts.
Step-by-step explanation:
In the first paragraph of this example, we learn about the way in which the Pevensie children were taken to the countryside in the book The Lion, the Witch, and the Wardrobe, from the saga The Chronicles of Narnia. We learn that these children were sent to a large house with a professor who had no family.
The second paragraph allows us to understand this situation better, as it tells us that children were often sent to families who had no children. This contributed to the development of a close relationship between the people involved.
By reading the second paragraph, we are more likely to understand how these relationships developed, and we might be more inclined to believe that such a relationship is possible between the Pevensie children and the professor.
