Solution seems ok but I do not understand the QUESTION itself. (It is clear to me in Statement-1 the possible values x can get and all those values are NOT even, in Statement-2 it can get odd and even values)
Could you explain in plain English what Statement-1 is sufficient for?
Or could you complete this sentence "Statement-1 is sufficient for ...................
Or would this completion be ok?
"Statement-1 is sufficient for answering the question 'if x is integer, is x even?'
Kudos (+1) if you find this post helpful.
