	Listed conductivities are for pure elements at 300ºK.

	Good quiz. I think that your comment should be in the header. I tried nickel, zinc, brass etc as answers. Also shouldn't copper be 100% that's what all the others are based on, that's why it's called the International Annealed Copper Standard.

	Elevatorman, you make an interesting point. The IACS was created in 1913, and 100% was set at the conductivity of the annealed commercially pure copper of the day, but processing techniques have improved since then and so commercially pure copper products now often have IACS conductivity values greater than 100%. This is because they can now remove more impurities from the metal. The number in the quiz is for essentially pure metal.

	Oh, and you're right; my first comment above really belongs in the bulleted list under the title, but apparantly there's no way to insert comments there yet.
