The statement that describes a purpose of a thesis statement is ".It shows a student’s point of view on a topic." Option 2 is correct.

A thesis statement presents the ideas of the writer in one or two sentences. It should introduce the topic of the paper as well as make a comment about the writer's position in relation to the topic. The thesis statement should tell your reader what the paper will deal with and keep the argument focused.

conclusions made on the basis of unstated or stated evidence are called inferences
