Why R not Q ? Ans : because otherwise black can force you to stalemate & if you try not to stalemate you end up losing instead. HOW ?

suppose you promote to Q :  [3. b8=Q Re2+ 4. Kd1 Rb2]
Scenario 1 : on move 5 if you capture black with your newly promoted Q then it's stalemate. 
Scenario 2 : on move 5 place your Q anywhere other than b file . But then Black rook simply checks from Rb1 and white is check mated. 

However, such scenario do not arise once you promote to Rook . Cheers.
(FossaFerox answer was pretty close . Only he didn't explore further. )


What about the scenario where say 5. Qc7 when white can block 5...Rb1+ with 6. Qc1 where there is no stalemate or checkmate?

There is no way to force a mate with just two knights.

Look at comment #327.

LET ME SAY THAT A ROOK WILL HELP GET THE CHECK-MATE WHERE A QUEEN IS OVER KILL AND COULD LEAD TO STALE MATE (NOT A CHECK-MATE} BOTTOM LINE - DOES THIS HELP????

Those idiots ask their stupid question even if the answer is given in the comment right above their own one. So this probably doesn't help. I think nothing can help them.

When the answer has been given dozens of times asking the same question means to show your complete stupidity. Period.
