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: Do older men with higher self-rated socioeconomic status have shorter telomeres?
Answer: men with higher self-rated socioeconomic status have shorter telomeres, possibly mediated through psychosocial rather than lifestyle factors or the presence of chronic disease. There may be cultural ethnic and age-related differences in social determinants of health.
Example Output: yes

Example Input: Question: Does mR Elastography demonstrate Increased Brain Stiffness in Normal Pressure Hydrocephalus?
Answer: This study demonstrates increased brain stiffness in patients with normal pressure hydrocephalus compared with age- and sex-matched healthy controls; these findings should motivate future studies investigating the use of MR elastography for this condition and the efficacy of shunt therapy.
Example Output: yes

Example Input: Question: Does degenerin channel activation cause caspase-mediated protein degradation and mitochondrial dysfunction in adult C. elegans muscle?
Answer: Constitutive cationic influx into muscle appears to cause caspase degradation of cytosolic proteins as the result of mitochondrial dysfunction, which may be relevant to ageing and sarcopenia.
Example Output:
yes
