Answer:
thesis
Explanation:
A "thesis" refers to the <em>main point</em> or<em> main idea</em> of a person's writing. It tells his position and present his information<u><em> in relation to his topic.</em></u> Since this is what the paper is actually all about, then this is the one which can be compared across different texts to see if a connection can be made. Thus, it is important that the thesis is<em> clear </em>and <em>specific.</em>
