The third paragraph of the body should contain the weakest argument, weakest example, weakest illustration, or an obvious follow up to the second paragraph in the body. The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the second paragraph. The topic for this paragraph should be in the first or second sentence. This topic should relate to the thesis statement in the introductory paragraph. The last sentence in this paragraph should include a transitional concluding hook that signals the reader that this is the final major point being made in this paper. This hook also leads into the last, or concluding, paragraph.
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.")
When you integrate quotations in this way, you do not use any special punctuation. Instead, you should punctuate the sentence just as you would if all of the words were your own. No punctuation is needed in the sentences above in part because the sentences do not follow the pattern explained under number 1 and 2 above: there is not a complete sentence in front of the quotations, and a word such as "says," "said," or "asks" does not appear directly in front of the quoted words.
