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: Does fTY720-Induced Lymphopenia Aggravate Mortality in a Murine Model of Polymicrobial Abdominal Sepsis?
Answer: Our data demonstrate that inhibition of T cell migration and induction of peripheral lymphopenia did not affect survival in a model of severe murine sepsis. The presence of reduced T- and B-cell numbers in the peripheral blood during a septic challenge did not negatively affect sepsis mortality in our model of severe abdominal sepsis. The absence of increased mortality under FTY720 treatment in the CASP model suggests that FTY720 treatment will probably not result in increased mortality in MS patients suffering from sepsis.

Output: no


Input: Consider Input: Question: Does presence of the full-length KIR2DS4 gene reduce the chance of rheumatoid arthritis patients to respond to methotrexate treatment?
Answer: Our results suggest that the response of RA patients with medium ESR values to MTX treatment may be dependent on the full-length KIR2DS4 gene.

Output: yes


Input: Consider Input: Question: Does reduction of treatment frequency and UVA dose substantially compromise the antipsoriatic effect of oral psoralen-UVA?
Answer: Reducing treatment frequency and UVA dose does not substantially compromise the therapeutic efficacy of PUVA.


Output: no
