Worst quiz I've ever seen
First of all, the "welcome" image is displayed throught all the pages covering certain answers. Secondly, there was no difficulty at all besides the incorrect answers. Thirdly this quiz uses an incorrect answer and an invalid question. The Okapi has black and white stripes, yet warranted an incorrect response. The faulty question stated that the sky is blue, whensky is not always blue, making this question invalid.
