Can somebody explain me Q69 OG 12

Can somebody explain me Q69 OG 12

Of the four numbers represented on the number line
above, is r closest to zero?
(1) q = -s
(2) -t < q



Does this question implicitly assumes that q,r,s and t are integers ?

<----|----|----|----|----> (number line)
q r s t

statement 1
1) q=-s
Assume s=2
so q =-s=-2
As r is in between q & s, so it will be closest to 0.
hence sufficient

statement 2
2) -t<q
assume t = 5
q>-5, so it can be -4,-3,-2,-1,0... as all are greater than -5
It doesn't give any information about r.
Hence not sufficient.

so the answer is A
