Quoted from the website:
"FreeRice is a sister site of the world poverty site, Poverty.com.
FreeRice has two goals:
1. Provide English vocabulary to everyone for free.
2. Help end world hunger by providing rice to hungry people for free.
This is made possible by the sponsors who advertise on this site.
Whether you are CEO of a large American corporation or a street child in India, improving your vocabulary can improve your life. It is a great investment in yourself.
Perhaps even greater is the investment your donated rice makes in hungry human beings, enabling them to function and be productive. Somewhere in the world, a person is eating rice that you helped provide. Thank you."
Basically, the ads at the bottom of the page (iTunes and a few others) are paying for every answer you get right, and that money is used to buy rice for the homeless.
I just thought I'd like everyone to have a heads up.
P.S.
To whom it may concern, this IS not spam. I AM George, who builds with legos and is 14.
