Answer 1

to promote the socialist views that he adopted as an adult

Sinclair wrote The Jungle to expose the exploitation of workers in the meatpacking industry and to advocate socialist reforms. (He later quipped, “I aimed at the public’s heart, and by accident I hit it in the stomach,” because readers focused on food safety.)
