500 Question Purity Test
IMPORTANT NOTE!!!
BEFORE you begin taking this test, scroll to the bottom to make sure that you
got the whole thing.
At the very bottom you should find the "submit" button.
If you don't, it means one of two things:
either your browser choked on the large number of checkboxes this test
presents, or a failure occured during the transfer of the test from the web
server to your browser.
In either case, it's no fun to fill out most of the test and then find out it's
not all there!
So, check first.
If the test is truncated, the only thing that can be done about it is for you
to try reloading it.
Check all boxes for which your answer is "yes"
The "submit" button is at the bottom.
