Rice anyone?

So, my sister Tamar got me addicted to this site called "freerice.com". It is a non-profit org. that helps the UN fight against hunger. There is a fun vocab test and for every question you get right it will donate a certain number of grains of rice to the fight against hunger. I got up to level 40 and then fell back down and can't get past level 37. Tamar is at 39, so I am feeling pretty vocab challenged, but she was always the smarter sis. I donated over 3000 grains of rice in just one sitting. Have fun!
