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: Is cytosine deamination a major cause of baseline noise in next-generation sequencing?
Answer: Baseline noise during NGS is mostly due to cytosine deamination, the source of which is likely to be both biologic and an artifact of thermocycling, and it can be reduced by UNG pretreatment.
Example Output: yes

Example Input: Question: Does cheating explain selective differences at high and low relatedness in a social amoeba?
Answer: These results suggest that social competition and something beyond solitary growth differences occurs during the vegetative stage when amoebae eat bacteria and divide by binary fission. The high degree of repeatability of our results indicates that these effects are strong and points to the importance of new approaches to studying interactions in D. discoideum.
Example Output: no

Example Input: Question: Does intracarotid Etomidate decrease the Interhemispheric Synchronization in Electroencephalogram ( EEG ) During the Wada Test?
Answer: Our study showed that the EEG effects of intracarotid ipsilateral injection of etomidate is not uniform in both hemispheres. Decrease in the interhemispheric synchronization of delta waves might serve as an indicator of ipsilateral effect of etomidate on the brain. Additional studies are needed to confirm our findings.
Example Output:
yes
