The tentative,, maybe ok, maybe not, answers.

? At the end of an any characteristic.-Z halfwave transmission line, the 
termination Z repeats itself --  with a reactance reversal.  .  Since 
there is no reactance in this termination, the Z at the end of the 93-ohm 
halfwave line is 50 +/- j0 ohms, the SWR is 1:1.

?  93/50 = 1.86:1.  

How did I do? 

-----------
Question 3:

In Question 1, if the SWR meter were moved from the 1/2 wave point to the 
1/4 wave point, what would the SWR reading be?.
