You and your friend are on vacation at Yellowstone Park. The plaque in front of a sulfur hot spring reads: "This sulfur spring is 80°C, has a pH of 2, and contains large amounts of sulfur which is oxidized by Sulfolobus species of archaea." Your friend is excited. "Boy, if those microbes are that tough they should be easy to grow in the lab. I think I'll work with those for my summer project." What do you think?

A. The sulfur spring is pretty extreme, but after a few days the individual archaea should have adapted to lab culture conditions.
B. The sulfur spring is pretty extreme, but after a few generations the species should have adapted to the lab culture conditions.
C. You agree, and decide to partner with your friend to work on this organism as well.
D. A species adapted to such extreme conditions would probably not be easy to culture in the very different conditions of a lab.
