q, r, s and t must be in the order shown.
Statement 1: q = -s
Case 1: s=1, q=-1
q=-1.
....0.....s=1.....t
Here, r must be in the RED PORTION between q and s.
Since the red portion includes 0, r will be closest to 0.
Case 2: s=10, q=-10
q=-10.
..............0...............s=10.....t
Once again, r must be in the RED PORTION between q and s.
Since the red portion includes 0, r will be closest to 0.
In every case, r will be in the red portion between q and s -- the portion that includes 0.
Thus, r will always be closest to 0.
SUFFICIENT.
Statement 2: -t < q
If t=10, then q>-10.
Thus, the number line could look like this:
q=-9...........r..........s............t=10.
No way to determine whether r or s is closest to 0.
INSUFFICIENT.
The correct answer is
A.
