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 mutational status of KIT and PDGFRA and expression of PDGFRA associated with prognosis after curative resection of primary gastrointestinal stromal tumors ( GISTs )?
Answer: Our data do not support the notion that expression of PDGFRA or mutations in KIT or PDGFRA are independent prognostic factors after curative resection of primary GIST.
Example Output: no

Example Input: Question: Does short-term enteral glutamine enhance protein accretion in burned children : a stable isotope study?
Answer: Rapid protein accretion does not occur with short-term enteral glutamine supplementation. Several days of glutamine supplementation may be required to restore plasma glutamine levels and stimulate protein synthesis.
Example Output: no

Example Input: Question: Does neuromuscular electrical stimulation-assisted gait increase muscle strength and volume in children with unilateral spastic cerebral palsy?
Answer: Eight weeks of daily NMES-assisted gait increases muscle volume and strength of the stimulated ankle dorsiflexors in children with unilateral spastic CP. These changes are use-dependent and do not carry over after the 8-week treatment period. Gastrocnemius volume also increased post-treatment with carryover at week 14.
Example Output:
yes
