Idon’t know why everyone was so happy when we reach

A. words and actions.

Explanation:

This is an excerpt from Wonder, a children's book written by Raquel Jaramillo, also known as R. J. Palacio.

In the excerpt, the author describes August's relationship with Zachary and Alex. Their feelings toward August are first explained through their actions- they do not see August quite often (August claims that he sees Christopher more, although he moved far away), and they have made new friends. However, the author explains that they are still nice to August, as they always say 'hello' when they see him. The author, therefore, reveals the words that Zachary and Alex use, in order to explain their feelings for August.
