Zoo<br>When we were in Chicago my friends and I went to the zoo. We spent the whole day there, observing the animals. The animals in the zoo appeared to be happy enough. However, by the end of the day my friend was very sad. She realized that seeing caged animals made her depressed.

Based on the paragraph above can we conclude that "The lions in the zoo were happy because they got to eat more food "?
It's impossible to say
