The test doesn't load. It's too bad, because based on the comment below, there was the question about the Nile versus the Amazon as the longest river in the world, which is the reason why that's the hardest test in the universe, but it is quite a simple question. It's the Nile. No, the Amazon, No, the Nile. No, the Amazon. No, the Nile. (Repeat a few thousand times.)

It is irritating that the quizzes that you hit let's play for some reason no longer open. Not sure what changed but it is irritating

Mary Beth Oles, The Nile is the longest river in the world. The Amazon is the largest. The question asked for the largest.
