Problem: Two researchers studied air quality over the North Pole, and over Antarctica. Dan was more fond of the south pole, so he studied Antarctica, while Colt liked reading about the North Pole. Which researcher learned less about higher levels of UV radiation reaching Earth?

A: Colt

Problem: John is interested in the history of science. He went to a science museum to learn more about microscopes. First he saw a Leeuwenhoek microscope, which was labeled as item A, then he saw a compound microscope of Leeuwenhoek's time, which was labeled as item B. At the very end of his museum tour he saw a modern compound light microscope, which was labeled as item C. Would item B have more or less lenses than item A?

A: more

Problem: Mark is a biologist. He is trying to see how to make chemical reactions within organism easier. To that end, he conducts two tests, test A an test B, on an organism. In test A he reduces catalysts from the organism, but in test B he induces catalysts in the organism. He needs to observe the outcomes of these tests. Would test B see less or more reactants colliding than test A?

A: more

Problem: Two rivers, The Minninnippi and The Cedar, flow into the same ocean. The Minninnippi is surrounded almost entirely by farm lands due its location in a flat area of the country that sees regular rainfall. The majority of these farms will have runoff from their crop soil flow into the river. The Cedar is located mostly inside an unpopulated forest. Currently, not much industrialization or settling by humans has happened near The Cedar. Is it more or less likely that the ocean water near The Minninnippi will experience hypoxia?

A:
