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: Are higher rates of viral suppression with nonnucleoside reverse transcriptase inhibitors compared to single protease inhibitors explained by better adherence?
Answer: A higher proportion of individuals using NNRTI-based regimens had viral suppression when compared to those taking single-PI-containing regimens, and this association was not confounded by higher levels of adherence. These results suggest that improved viral suppression on NNRTI regimens compared to single-PI regimens is more closely associated with regimen potency than higher levels of adherence.
Example Output: no

Example Input: Question: Does ischemic preconditioning attenuate renal ischemia-reperfusion injury by inhibiting activation of IKKbeta and inflammatory response?
Answer: The evidence suggests that IKKbeta may play a role in renal I/R injury and give rise to the generation of NGAL. It appears that IPC may attenuate renal injury and the expression of NGAL following acute I/R injury. IKKbeta may offer a clinically accessible target for preventing renal injury following I/R.
Example Output: yes

Example Input: Question: Does low Cerebrospinal Fluid Amyloid-Beta Concentration be Associated with Poorer Delayed Memory Recall in Women?
Answer: CSF biomarkers correlate with delayed memory scores in CERAD-NB in women, and women may have more actual AD pathology at the time of the investigations than men.
Example Output:
yes
