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 biphasic redistribution of muscarinic receptor and the altered receptor phosphorylation and gene transcription underlying mechanisms in the rat heart during sepsis?
Answer: The m2AChR in the rat heart was externalized from light vesicles to sarcolemma (overexpression) during early sepsis but internalized from surface membranes to intracellular sites (underexpression) during late sepsis. Furthermore, changes in the receptor phosphorylation and gene transcription are responsible for the biphasic redistribution and the altered expression of m2AChR in the rat heart during the progression of sepsis.
Example Output: yes

Example Input: Question: Does multiple Intercostal Space Electrocardiogram allow Accurate Localization of Outflow Tract Ventricular Arrhythmia Origin?
Answer: The combined TZ index outperformed other ECG criteria to differentiate left from right OT-VA origins.
Example Output: yes

Example Input: Question: Does valerian appear to reduce symptoms for patients with chronic insomnia in general practice using a series of randomised n-of-1 trials?
Answer: Valerian was not shown to be appreciably better than placebo in promoting sleep or sleep-related factors for any individual patient or for all patients as a group.
Example Output:
no
