If i and j are integers, is i + j an even integer?
(1) i < 10 --> no info about j. Not sufficient.
(2) i = j --> \(i+j=j+j=2j\), as \(j\) is an integer then \(2j\) is an even number. Sufficient.

Note that if we were not told that \(i\) and \(j\) are integers then this statement would not be sufficient as in this case \(j\) could be for example 1.5, so \(i+j=j+j=2j=3=odd\) or \(j\) could be for example 1.1, so \(i+j=j+j=2j=2.2\neq{integer}\).

Answer: B.
