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 Input:
Question: Do armband activity monitor data correlate with reported pain scores in patients receiving vertebroplasty?
Answer: Activity monitors can be used to objectively record changes in activity following vertebroplasty procedures. Patient-reported pain or disability scores do not correlate with activity monitor-measured activity or sleep metrics.

Ex Output:
no


Ex Input:
Question: Does effective inhibition of nitric oxide production by aminoguanidine reverse hypotension in endotoxaemic rats?
Answer: AG inhibited NO formation in a dose-dependent way. Yet, AG had no haemodynamic effects, suggesting a minor cardiovascular influence of iNOS in this endotoxin model, in parallel to what has been found in microbial sepsis.

Ex Output:
no


Ex Input:
Question: Does mouse strain determine the outcome of wound healing after myocardial infarction?
Answer: The outcome of infarct healing in mice strongly depends on genetic background. On the basis of our results, we suggest that for studies on infarct rupture, the 129S6 mouse is the background of choice, whereas BalbC and Swiss mice are the preferred models to study infarct thinning post-MI.

Ex Output:

yes
