If m, n, p, and q are distinct integers, are they consecutive?
(1) q-m=3
(2) m<n<q and m<p<q
OA is C. [spoiler]My answer is E because we don't have any limitation on the integers: even if we consider 1 and 2 together, all we know is that q is the largest, and m is the smallest. consider the list m n p q: 1 3 3 4. where am i wrong with this?[/spoiler]

It is mentioned that the numbers are distinct. so they cannot be same. hence the condition 1 3 3 4 is invalid.
B tells us the position of the numbers and A gives the range.
Hence C

The problem is more with the wording of the question, which can be interpreted different ways.scoowhoop wrote:Given (1) and (2) couldn't the sequence still be either, mpnq or mnpq? I dont' see how C can be correct.
If you interpret it as "consecutive in that order", then the answer is E.
However, a more general interpretation of "consecutive" (i.e. we just need the 4 integers to be consecutive, in no particular order) would lead to C.
For example, how would you answer the question:
"Are 2,4,5 and 3 consecutive integers?"
Under the first interpretation they're not, but under the second interpretation they are.
