Review the passage:
Richie loves to walk his friends' dogs at Lake Eola
Park. For example, Kim's Labrador retriever Murphy or Gary's
bulldog Kembo. Beautiful women, Richie has learned, gravitate toward guys
with cute dogs.
You chose the first part, Richie loves to walk his friends' dogs .... This part has a main clause: Richie is the subject; loves is the verb. A fragment will not have a main clause.
