After reading the first 12 chapters of THE BELL JAR, I have to write a friendly letter to Esther giving her advice and support. I have to include quotes from the book and this is what I have so far. can I get some feedback?

This is good but I personally don't recommend you to write prepositions at the first sentence.

Explanation:

In my opinion, putting prepositions at the first sentence aren't so proper.

the correct answer is the following.

one of the groups i belong to is the boy scouts. this is a problem-solving group because it has tasks that we need to solve in order to other people in different activities such as the rescue of lost pets, or elder people in need.

the other group i belong to is kids pro environment, and is an information-sharing group that tries to create conscience about the risks and problems that generate pollution in our cities. we share information to other students and parents on the importance of keep our communities clean and our skies clear.  

i think she wanted to protect her children from the extreme racism of the american south.
