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: 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.

Ex Output:
no


Ex Input:
Question: Is evidence that the lung Adenocarcinoma EML4-ALK fusion gene caused by exposure to secondhand tobacco smoke during childhood?
Answer: The EML4-ALK fusion gene is not enriched in tumors from individuals exposed to SHS during childhood.

Ex Output:
no


Ex Input:
Question: Does timosaponin A3 induce hepatotoxicity in rats through inducing oxidative stress and down-regulating bile acid transporters?
Answer: TA3 triggers liver injury through inducing ROS generation and suppressing the expression of BA transporters. Mangiferin, an active component in Anemarrhena, may protect hepatocytes from TA3-induced hepatotoxicity.

Ex Output:

yes
