The article that I read was How to Conclude, which basically went over how to effectively  conclude a presentation or speech. The author talks about using techniques such as a sign post to signal   the conclusion of your speech and then solidify your conclusion with a clincher or statement that will keep your argument around in peoples minds.

I think that the idea of a clincher is really important when giving presentations because it is the final idea or thought that you could share with the audience. i bruce that the last impression you sort of set with the audience is the impression that they would remember, so it would be good to end on a strong and dominant point.
