St1:
If x=y, then PQ = QR. If PQ = x, QR = x, and we know PR must be less than 2x but we can't be sure if it's more or less than x. Insufficient.

St2:
If y=z, then PQ=PR and we can now say answer the inequality. Sufficient.

Clear winner B

For one side of a traingle to be greater than other side, the opposite angle should be greater
That is in this case
y>z for PQ to be greater than PR

1) Not Suff.
Just says PQ = QR..... PR can be greater or less than PQ

2) Suff
Says PQ=PR hence answered
