Read each subsection carefully and then
indicate whether each scenario is possible or
impossible under the Heisenberg Uncertainty Principle (HUP)
by circling either ``Allowed'' or ``Not Allowed''.
Hint: Do not guess if you are unsure; incorrect responses will be
penalized. Each subsection will receive full-credit for the correct
response, half-credit for no response, or zero points for an incorrect
guess.
