    Something is wrong with the quiz (1st one). Whenever I go to read the question the page goes blank and I have to reload. Then I click an answer and the page goes white. It froze up my computer completely for several minutes. Then a page came up saying there was a error reloading page please restart your computer. I don’t like the way that sounds.
