Here we have an explanatory, mildly argumentative thesis that enables the writer to express an opinion. We infer from the use of the word convincing that the writer will judge the various reasons for protecting the rights of AIDS patients; and, we can reasonably assume, the writer himself believes in protecting these rights. Note the contrast between this second thesis and the first one, where the writer committed himself to no involvement in the debate whatsoever. Still, the present thesis is not as ambitious as the third one, whose writer implicitly accepted the general argument for safeguarding rights (an acceptance he would need to justify) and then took the additional step of evaluating the merits of those arguments in relation to each other. (Recall that Anthony Jones's plan was the "most sensible.")
A research proposal is another kind of a complicated academic writing you may be asked to complete pursuing a degree. It differs greatly from any other dissertation or thesis sample, as it is a practical proposal on some scientific investigation. It may even be of greater importance to your academia than any other paper you have submitted before. The tricky part in writing your research proposal paper is that it has to be 100% unique and original. No one will analyze a partially plagiarized research proposal, as it is supposed to promote a good start to your future career. Thus, you have to make sure you paper is grammatically flawless, well structured, and plagiarism free.
