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.

Ex Input:
Question: Do simple counts of ADL dependencies adequately reflect older adults ' preferences toward states of functional impairment?
Answer: Our results suggest that the count of ADL dependencies does not adequately represent the utility for a health state. Cost-effectiveness analyses and other evaluations of programs that prevent or treat functional dependency should apply utility weights rather than relying on simple ADL counts.

Ex Output:
no


Ex Input:
Question: Are chronic obstructive pulmonary disease patients with psychiatric disorders at greater risk of exacerbations?
Answer: Patients with psychiatric disorders are at greater risk of exacerbations treated in an outpatient setting but not those treated in an inpatient setting. These outpatient-managed exacerbations account for a significant proportion of the healthcare burden for COPD, so interventions should target patients with psychiatric disorders to improve management of COPD.

Ex Output:
yes


Ex Input:
Question: Do inpatient admission for febrile seizure and subsequent outcomes differ in children with vaccine-associated versus non-vaccine associated febrile seizures?
Answer: The risk of hospitalization for index FS or select subsequent FS outcomes did not differ between VA or NVA-FS. This suggests that the follow-up care of children with VA-FS does not warrant attention beyond that for NVA-FS.

Ex Output:

no
