<em>To educate people about adopting dogs</em> is the Purpose. This true because the sentence begins with "to educate". This means that the purpose of the subject is to educate.
<em>People in the community</em> is the Audience. Audience refers to people. Here, the audience mentioned was specific - "people in the community"
