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.

Input: Consider Input: Question: Do feasibility of using tissue Doppler velocities in stress echo during upright bicycle exercise?
Answer: Tissue velocities decreased from base to apex. Mean difference between the raters was-0.02 cm/sec at rest and 0.45 cm/sec during exercise. Peak-to-peak variability was lowest in the mitral ring during rest (10-14%) and increased at peak exercise (15-21%). The proportion of segments eligible for analysis was 84% in the septum and 67% in the anterior wall during exercise. Thus, in patients with normal coronary arteries, tissue Doppler velocities decrease from base toward the apex during bicycle exercise. Interrater agreement is reduced during exercise and beat-to-beat variability is lowest in the mitral ring.

Output: yes


Input: Consider Input: Question: Do associations of Heart Rate With Inflammatory Markers Are Modulated by Gender and Obesity in Older Adults?
Answer: Faster HR is associated with proinflammatory state in elderly patients; this association seems to be limited to women with higher BMI.

Output: yes


Input: Consider Input: Question: Is a Novel Mutation in the DNA Binding Domain of NFKB Associated with Speckled Leukoplakia?
Answer: The identification of a substitution mutation L140Q within the DNA binding domain of NFKB in OL suggests that NFKB mutation may be relatively an early event during transformation. To the best of our knowledge, this study is the first to have identified a missense mutation in NFKB in OL.


Output: yes
