A viable proposal can't be replied with a straightforward "yes" or "no." A proposition isn't a theme; nor is it a reality; nor is it a feeling. "Explanations behind the fall of socialism" is a theme. "Socialism fallen in Eastern Europe" is a reality known by instructed individuals. "The fall of socialism is the best thing that at any point occurred in Europe" is a sentiment. (Superlatives like "the best" quite often lead to inconvenience. It's difficult to gauge each "thing" that at any point occurred in Europe. What's more, shouldn't something be said about the fall of Hitler? Couldn't that be "the best thing"?) A decent proposal has two sections. It should advise what you intend to contend, and it should "broadcast" how you intend to contend—that is, the thing that specific help for your case is going where in your exposition.
