Data Sufficiency (DS) | Re: Is the line PQ parallel to the line SR? (1) w = q (2) y = z

statement 1- w=q, then it will solve the question, using externally angle theorem, PQ is equal to SR.
statement 2- y=z, then it does not let us know about angle of line PQ and SR.

So the answer to the equation is A.
