If k,n, and r are integers, let k^(n,r) be defines to be true onlu if n<k<r. If -2^(n,0) is true, which of the following could be a possible value of n?
I. -3, II. -1, III. 3
a) I only
b) III only
c) I and II
d) I and III
e) II and III

given that k^{(n,r)} is true if and only if n<k<r, and knowing that -2^{(n,0)} then k=-2 and r=0. so n<-2<0, which means must be less than -2. from the options you have, -3 is the only value that satisfies this ineqiality and allows it to hold true. thus, the answer here would be a.) I only
