Remind the reader that you've demonstrated this thesis throughout the span of your paper. For instance, in case you're contending that your readers ought to get their pets from animal sanctuaries as opposed to pet stores, you may say, "In case you were thinking about that doggy in the pet-shop window, remember that your buy will uphold 'pup factories' as opposed to protecting a poor dog, and consider choosing your new companion at your neighborhood animal safe house." This model gives the reader the thesis of the paper as well as a token of the most remarkable point in the argument!
