There are two main ideas for each passage, in the first one it mentions the positive outcomes of having a pet in class; it can help children with health problems and nervousness in students will decrease. In this sentences it supports the idea of a pet in class, saying the positive results of it and how it helps or it will help children. 
In the second passage it mentions the negative outcomes of having a pet in class; they will make some health problems worst and the nervousness in students will increase around them. These two ideas are against the possibility of having a pet in class, mentioning how it will affect students instead of helping them. 
What makes these two passages different is the opinion towards one main idea: pets in class. One passage supports it and one is against it.
