(1)不充分，r可以大于0，也可以小于0。

（2）单独也不充分，不知道m or r的具体值

1&2， 也不行，m>0, 3om=or,get the key: r=18; m<0, get the other key: r=36.

有个和数学无关的问题，

When you arrive at the test center you will be required to present at least one form of GMAC®-approved, non-expired, government-issued identification (ID) that clearly shows your name (in Roman characters, as in this letter), photograph, signature, and date of birth. With some restrictions and exceptions as noted below and on www.mba.com, the only approved forms of ID are a passport, driver's license, national or state ID card, or military ID card.
