Does the statement x is a positive integer mean that x can be 0?

On the GMAT, two data sufficiency statements always provide TRUE information and these statements never contradict each other. But , for this question, the statements, do not contradict. x could be 15, so the sum of 5 consecutive integers (1 + 2 + 3 + 4 + 5 = 15) and the sum of 2 consecutive integers (7 + 8 = 15). It can also be 5, again 5 is the the sum of 5 consecutive integers (1 + 0 + 1 + 2 + 3 = 5) as well as the sum of 2 consecutive integers (2 + 3 = 5). Hope it's clear. Thanks a lot for the clarification and also the explanation

St 1: x is the sum of two consecutive integers > can be a+2, a+3 or a, a+1. So x will change, as we don't know the order of the consecutive numbers
St 2: X is sum of 5 consecutive integers > can be a+5, a+6, a+7, a+8, a+9 or a+12, a+13..a+17. Again x will change. we don't know the order of consecutive numbers
1) 2) => no clarity on the value of consecutive numbers. hence E.
