E.

stat 1: if t = 11 then w<0>0; insuff

stat 2: if t = 19 then w>0 if t = 11 then w<0; insuff.

together: same as stat 2. Insuff.

1: Could be 10.00000000000000000000000000000000000000000001 degrees (just easier to say 10 degrees) or 1million degrees. Insuff.

2: Could be 20 degrees or 0 degrees insuff.

1 and 2: still insuff. Could be 10 degrees or 20 degrees.
