Example Input: Question: Are `` These issues n't talked about at home '' : a qualitative study of the sexual and reproductive health information preferences of adolescents in Vanuatu?
Answer: Providing adolescents with comprehensive SRH information can have life-long protective benefits, however there are important content gaps in information currently provided in Vanuatu.

Example Input: Question: Does deep brain stimulation of the ventromedial prefrontal cortex cause reorganization of neuronal processes and vasculature?

Example Output:
yes
