Free Rice I guess this guy developed it originally to help his son study for the SATs. Now it is a tool against world hunger. You are given a word and four choices for a definition/synonym. For every correct answer, 20 grains of rice are purchased from the banners of adds at the bottom of the page. The United Nations World Food Program distributes the rice. So if you're ever bored, or tired of taking surveys, or just wondering where you vocabulary skills rank, hit up the site.
