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 comprehensive analysis suggest simple processes underlying EEG/ERP - demonstration with the go/no-go paradigm in ADHD?
Answer: We show how these processes accord with and provide insight on the waveforms reported in the literature.
Example Output: yes

Example Input: Question: Is pre-surgical cortical activation to food pictures associated with weight loss following bariatric surgery?
Answer: We found that neural activity in previously established regions associated with cognitive and behavioral self-regulation predicts weight loss following bariatric surgery. These preliminary findings highlight the role of neural circuitry in the success and maintenance of weight loss and suggest a possible future use of fMRI in screening LAGB surgery candidates.
Example Output: yes

Example Input: Question: Are distinctive characteristics of bronchial reticular basement membrane and vessel remodelling in chronic obstructive pulmonary disease ( COPD ) and in asthma : they the same disease?
Answer: The characteristics of Rbm remodelling are quite different in asthma and COPD.
Example Output:
no
