Your job is to figure out, based on a correct prompt (S1), if another prompt (S2) is also correct. 
Answer "0" if any event or situation that can be described by S1 would also fit S2. Answer "1" if S2 could describe an event or situation that fit S1, but could also describe situations that don't fit S1. Answer "2" if any event or situation that could possibly be described with S1 would not fit S2.

Example 1 -
Input: S1: Parents seemed unable to distinguish  good  from  substandard  care.
S2: There seemed to be an inability to distinguish good from substandard care among parents.

Example 2 -
Input: S1: The President apparently spoke to Secretary Rumsfeld for the first time that morning shortly after 10:00.
S2: There is no reason to believe that Secretary Rumsfeld and the President spoke after 10:00.
Output: 2.

Example 3 -
Input: S1: United 93 crashed in Pennsylvania at 10:03:11, 125 miles from Washington, D.C.
