If we had the most powerful optical microscope in the world stacked on top of the next most powerful optical microscope in the world, we would

1) probably see atoms,
2) probably be able to photograph atoms even if we couldn't see them,
3) still not be able to see an atom,

because atoms are
4) invisible.
5) visible when illuminated with infrared light.
6) material particles which have mass and size.
7) smaller than the wavelengths of visible light.

Question 2

If all potatoes are selling at the same price per kilogram, a housewife who plans to peel the potatoes would get more potato for her money if she bought

1) small potatoes.
2) medium potatoes.
3) large potatoes.
4) no difference.

This is because she
5) would get more potatoes per kilogram.
6) would get less potatoes per kilogram.
7) would get less peelings because of less surface area per pound.
8) buys weight, so any size per kilogram gives the same mass of potatoes.
