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 differential behavior patterns in cynomolgus monkey Macaca fascicularis in home cage in response to human gaze?
Answer: These results indicate that, even in their home cage, monkeys display a heightened level of awareness when gazed upon by a human observer, suggesting that human gaze may elicit emotional reactions. Further, under the human gaze, distinct behavioral subpatterns were apparent within the monkey cohort in our study, indicative of subgroups within the cohort.
Example Output: yes

Example Input: Question: Does the phospholipase A ( 2 ) inhibitor methyl indoxam suppress diet-induced obesity and glucose intolerance in mice?
Answer: These results show that oral supplementation of a diabetogenic diet with the Pla2g1b inhibitor methyl indoxam effectively suppresses diet-induced obesity and diabetes in mice. This suggests that Pla2g1b inhibition may be a potentially effective oral therapeutic option for treatment of obesity and diabetes.
Example Output: yes

Example Input: Question: Is a comprehensive geriatric assessment more effective than clinical judgment to identify elderly diffuse large cell lymphoma patients who benefit from aggressive therapy?
Answer: CGA is an efficient method to identify elderly DLCL patients who can benefit from a curative approach with anthracycline-containing immunochemotherapy. Further study is needed to discern why unfit patients seem to have poor outcomes because of poor tolerance but also because of lymphoma refractoriness to intensive therapy.
Example Output:
yes
