Question: is \(m\) greater than \(n\)
Inference: Does \(m\) lie to the right of \(n\)
Statement 1(1) \(m-1\) and \(n+1\) are consecutive integers
\(m-1\) denotes a position one unit to the left of \(m\)
\(n+1\) denotes a positon one unit to the right of \(n\)

We see that Case 2, Case 4, and Case 6 satisfy the criteria. In all cases \(m > n\). Hence, this statement is sufficient to conclude. We can eliminate B, C, and E.
Statement 2(2) \(\frac{m}{n}\) is an even integer
This statement alone is not sufficient. For example, in case 2, m = 2 and n = 1. In this case \(m > n\).
However in case 5, m = 0 and n = 1. In this case \(m < n\)
Hence this statement alone is not sufficient.
