Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[EX Q]: Question: Is retinol-binding protein-4 strongly associated with insulin sensitivity in normal pregnancies?
Answer: The increased fat mass and insulin resistance during normal pregnancy was best explained by measures of fat mass. However, the increase in RBP4 from early to late pregnancy, associated with a decline in insulin sensitivity, potentially indicates interactions with glucose metabolism.
[EX A]: no

[EX Q]: Question: Is neutrophil-lymphocyte ratio a reliable predictive marker for early-stage diabetic nephropathy?
Answer: Increased NLR was significantly associated with DN, and high NLR values may be a reliable predictive marker of early-stage DN.
[EX A]: yes

[EX Q]: Question: Does ultrasonographic assessment of amniotic fluid reflect actual amniotic fluid volume?
Answer: Both amniotic fluid index and two-dimension amniotic fluid pocket appear to be inaccurate predictors of actual oligohydramnios or polyhydramnios when compared with dye-dilution calculations of actual amniotic fluid volume.
[EX A]:
no
