A. Animal rights
B. Medical testing on animals
C. When john muir started sierra club
D. Activism in the US
D) Activism in the US is a good topic for the 4 to 5 research paper. It’s quite a debatable and relevant issue to discuss. So, the student should search for enough evidence and credible sources to support the main idea.
The topic d) “Activism in the US “fit the best in this case. This topic is not broad enough for a Bachelor’s or Master’s degree but is arguable sufficiently for conducting research. The student should involve some historical background, then write about recent examples of activism, and show the outcomes of this issue in different aspects.
