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 copy-number variations enriched for neurodevelopmental genes in children with developmental coordination disorder?
Answer: These findings suggest that there may be shared susceptibility genes for DCD and other neurodevelopmental disorders and highlight the need for thorough phenotyping when investigating the genetics of neurodevelopmental disorders. Furthermore, these data provide compelling evidence supporting a genetic basis for DCD, and further implicate rare CNVs in the aetiology of neurodevelopmental disorders.
Example Output: yes

Example Input: Question: Is tumor invasion depth a useful pathologic assessment for predicting outcomes in cervical squamous cell carcinoma after neoadjuvant radiotherapy?
Answer: The TID or TIDC measured at the cervical internal surface is a useful and easily applied pathologic prognostic factor for distant metastasis and survival outcomes in patients with cervical squamous cell carcinoma treated with neoadjuvant RT or CCRT.
Example Output: yes

Example Input: Question: Is twin vaginal delivery associated with lower umbilical arterial blood pH of the second twin and less intrapartum blood loss?
Answer: Twin vaginal deliveries were associated with slightly but significantly lower UmA-pH of the second twin, whereas twin cesarean delivery was associated with significantly larger intrapartum blood loss. Not only the neonatal risk but also the maternal risk should be taken into account when an optimal delivery mode for the twin pregnancy is considered.
Example Output:
yes
