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: Is nuchal cord associated with adverse perinatal outcome?
Answer: Nuchal cord is not associated with adverse perinatal outcome. Thus, labor induction in such cases is probably unnecessary.
Example Output: no

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 high or low calcium intake increase cardiovascular disease risks in older patients with type 2 diabetes?
Answer: High or low calcium intake increases cardiovascular disease risks. We suggest that "moderate" intake of 402-600 mg Ca/day (approximately 67%-100% of Taiwan RDA for Ca) and adequate Mg intake (or meeting RDA for Mg) with Ca:Mg intake ratio of 2.0-2.5 are important for reducing cardiovascular disease risks in older patients with diabetes.
Example Output:
yes
