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.

Example 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.
Example Output: no

Example Input: Question: Does the presence of high-grade prostatic intraepithelial neoplasia or atypia on prostate biopsy adversely affect prostatectomy outcomes for patients otherwise eligible for active surveillance?
Answer: The presence of HGPIN or ASAP does not increase the risk of upgrading, upstaging, or adverse pathology at the time of prostatectomy for patients who meet the AS criteria. If otherwise suitable, HGPIN and ASAP should not impact the decision to choose AS. However, analysis of prospective AS trials is required to determine if HGPIN or ASAP impacts tumor progression once on AS.
Example Output: no

Example Input: Question: Does genome editing of isogenic human induced pluripotent stem cells recapitulate long QT phenotype for drug testing?
Answer: Our study demonstrates that iPSC-CM-based disease models can be rapidly generated by overexpression of dominant negative gene mutants.
Example Output:
yes
