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 the Randomized Olmesartan and Diabetes Microalbuminuria Prevention ( ROADMAP ) observational follow-up study : benefits of RAS blockade with olmesartan treatment sustained after study discontinuation?
Answer: Development of microalbuminuria is a valid marker for future CV events. RAS blockade with Olmesartan might cause sustained reduction (legacy effect) of micro- and macrovascular events.
Example Output: yes

Example Input: Question: Are levels of soluble CD30 in cord blood and peripheral blood during childhood correlated with the development of atopic disease or a family history of atopy?
Answer: These findings indicate that the sCD30 concentration in cord blood is not a reliable prognostic indicator of, nor a useful diagnostic marker for, atopic disease in children up to 7 years of age. If such correlations do exist, they might be masked by age-dependent variations in the circulating levels of sCD30, which may reflect individual differences in the maturation of children's immunological responses.
Example Output: no

Example Input: Question: Is pre-operative Evaluation of Eustachian Tube Function Using a Modified Pressure Equilibration Test Predictive of Good Postoperative Hearing and Middle Ear Aeration in Type 1 Tympanoplasty Patients?
Answer: ET function measured with a modified pressure equilibration test using an inflation-deflation manometric method is a good indicator of an aerated middle ear and is predictive of improved postoperative hearing.
Example Output:
yes
