(2) $$q||s$$

we can say if we get a relation between line p and s..
if line p and s are parallel, ans is YES

lets see the statements

(1) $$p||r$$ and $$r||t$$
Just tells us that p||r||t
but no relation between p and s
insuff

(2) $$q||s$$
again nothing between p and s
Insuff

combined
nothing still between p and s
insuff
