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 inhibition of late sodium current attenuate ionic arrhythmia mechanism in ventricular myocytes expressing LaminA-N195K mutation?
Answer: Inhibition of late I
Example Output: yes

Example Input: Question: Does developmental changes in spatial distribution of in vivo fluorescence and epidermal UV absorbance over Quercus petraea leave?
Answer: The spatial pattern of epidermal UV-screen over the area of oak leaves is related to leaf anatomy during development. In vivo spectroscopy and fluorescence imaging of the leaf surface showed the distribution of pigments within the leaf and hence can provide a tool to monitor optically the leaf development in nature.
Example Output: yes

Example Input: Question: Does violence influence early pregnancy loss?
Answer: Although physical violence was very prevalent in the study population, exposure to violence did not influence the risk of SAB.
Example Output:
no
