Although electrons do not normally have precise velocities, you can cause an electron to have a (fairly) precise velocity by
 
  A) measuring both its position and velocity at an earlier time.
  B) measuring its position.
  C) measuring its frequency.
  D) measuring its velocity.
  E) measuring the force it exerts on another electron.

Question 2

Does biological evolution violate the law of entropy, and why or why not?
 
  A) No, because the energy increase of Earth's living organisms is exactly balanced by the energy decrease of the radiation flowing through those organisms.
  B) No, because the increase in the entropy of the radiation passing through living organisms is greater than the decrease in the entropy of those organisms.
  C) No, because Earth's organisms actually increase their own entropy during evolution, despite the appearance that they are becoming better organized.
  D) Yes, because this law is violated in situations involving energy from the sun.
  E) Yes, because this law is violated when new species are created on Earth.
