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 fructose Coingestion Accelerate Postexercise Muscle Glycogen Repletion?
Answer: Combined ingestion of glucose plus fructose does not further accelerate postexercise muscle glycogen repletion in trained cyclists when ample carbohydrate is ingested. Combined ingestion of glucose (polymers) plus fructose or sucrose reduces gastrointestinal complaints when ingesting large amounts of carbohydrate.
Example Output: no

Example Input: Question: Does microRNA-181a promote tumor growth and liver metastasis in colorectal cancer by targeting the tumor suppressor WIF-1?
Answer: Our data demonstrate that miR-181a expression is associated with CRC liver metastasis and survival. miR-181a has strong tumor-promoting effects through inhibiting the expression of WIF-1, and its potential role in promoting epithelial-mesenchymal transition.
Example Output:
yes
