Answer:
C. State several central ideas in your thesis statement.
Step-by-step explanation:
When writing research papers or articles, it is imperative that the problem statement or what the researcher intends to achieve with his research is clearly stated. This gives a sense of direction to the researcher while also enlightening the reader what the research is all about. Therefore, a thesis problem statement is that one sentence which gives the main idea of a research paper or article. The thesis statement should be framed in such a way that it centers on a central idea. Multiple central ideas should be avoided as this may lead to losing track of the main or central research focus.
