答案:E
解析:
"t exceeds s" is interpreted mathematically as the value of t-s and is evaluated as follows:
t-s = (1 + (s/2))-s
= 1 + ((1 + (1/2) + (1/4) + (1/8) + (1/16) + (1/32))/2
-(1 + (1/2) + (1/4) + (1/8) + (1/16) + (1/32))
= 1 + (1/2) + (1/4) + (1/8) + (1/16) + (1/32) + (1/64)
-1-(1/2)-(1/4)-(1/8)-(1/16)-(1/32)
= 1/64
