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: Does pimecrolimus affect Langerhans cells in murine epidermis?
Answer: It is therefore unlikely that topically applied pimecrolimus affects epidermal LCs, in contrast to corticosteroids.
Example Output: no

Example Input: Question: Does bacteriuria in patients with a continent ileal reservoir for urinary diversion regularly require antibiotic treatment?
Answer: The present results indicate that asymptomatic bacteriuria in patients with a continent ileal reservoir for urinary diversion is generally of no clinical importance and should not be treated with antibiotics. This conclusion is based on the observations that the bacterial strains growing in the reservoir changed spontaneously indicating colonization rather than infection. Raised titres of antibodies against E. coli correlated weakly with bacterial growth. The observed elevations in antibody titres were usually just above the normal upper limit.
Example Output: no

Example Input: Question: Is vascular endothelial dysfunction in cyclosporine-treated rat aortas associated with serum total homocysteine levels?
Answer: These data suggested a possible link between serum tHcy and decreased vascular sensitivity to endothelium-dependent vasorelaxation in control aortae, but CsA-induced vascular endothelial dysfunction was not associated with an effect of the drug on homocysteine metabolism.
Example Output:
no
