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 maternal serum concentrations of nicotinamide and related metabolites in late pregnancy associated with a lower risk of offspring atopic eczema at age 12 months?
Answer: This is the first study linking maternal serum concentrations of nicotinamide and related metabolites to the risk of atopic eczema in the offspring. The findings point to potentially modifiable maternal influences on this complex and highly prevalent condition.
Example Output: yes

Example Input: Question: Is muscle dysfunction during exercise of a single skeletal muscle in rats with congestive heart failure associated with reduced muscle blood supply?
Answer: The cause of contractile dysfunction in a single exercising skeletal muscle in rats with CHF cannot be explained simply by reduced blood supply. In addition, absence of changes in high-energy phosphates and metabolites indicate that the oxidative metabolism of SOL is intact in rats with CHF.
Example Output: no

Example Input: Question: Do all aggressive lymphoma subtypes share similar outcome after front-line autotransplantation : a matched-control analysis by the Groupe d'Etude des Lymphomes de l'Adulte ( GELA )?
Answer: This cohort study confirms the high efficacy of front-line ASCT in responding aggressive B-NHL patients with adverse prognostic factors.
Example Output:
no
