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 learning trajectories of children with special health care need across the severity spectrum?
Answer: Even children with less complex SCHN are at risk for academic failure. Early identification, together with integrated health and educational support, may promote stronger pathways of educational attainment for these children. Achieving these better outcomes will require the involvement of both educational and health practitioners.
Example Output: yes

Example Input: Question: Does tRAIL receptor deletion in mice suppress the inflammation of nutrient excess?
Answer: These data advance the concept that macrophage-associated hepatic and adipose tissue inflammation of nutrient excess requires TR signaling.
Example Output: yes

Example Input: Question: Are v600E BRAF mutations alternative early molecular events in a subset of KIT/PDGFRA wild-type gastrointestinal stromal tumours?
Answer: BRAF mutations represent an alternative molecular pathway in the early tumorigenesis of a subset of KIT/PDGFRA wild-type GISTs and are per se not associated with a high risk of malignancy. Mutations in KIT, PDGFRA and BRAF were mutually exclusive in this study. Results from this and a previous study indicate that BRAF-mutated GISTs show a predilection for the small bowel (four of five tumours), but this needs further evaluation in larger studies.
Example Output:
yes
