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.

Input: Consider Input: Question: Is premature immunosenescence associated with memory dysfunction in rheumatoid arthritis?
Answer: RA patients had reduced memory performance compared to healthy controls. Expansion of activated and senescence-associated T cells was correlated with poor memory performance.

Output: yes


Input: Consider Input: Question: Is human endogenous retrovirus ( HERV ) expression induced by treatment with the histone deacetylase ( HDAC ) inhibitors in cellular models of HIV-1 latency?
Answer: We show that HDAC inhibitors did not substantially increase the transcription of the analysed HERV env or pol genes, suggesting that histone acetylation is not crucial for controlling HERV expression in these experimental models and in ex vivo primary human T cells. Importantly, this indicates that unwanted HERV expression does not appear to be a barrier to the use of HDAC inhibitors in HIV-1 cure strategies.

Output: no


Input: Consider Input: Question: Does adherence to Dietary Recommendations for Food Group Intakes be Low in the Mexican Population?
Answer: These results reveal the poor dietary quality of the Mexican population and the urgent need to shift these habits. If current intakes continue, the burden of disease due to obesity and noncommunicable chronic diseases will likely remain elevated in the Mexican population.


Output: yes
