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 Q]: Question: Do integrin-associated complexes form hierarchically with variable stoichiometry in nascent adhesions?
Answer: These observations suggest a working model for NA assembly whereby transient α-actinin-integrin complexes help nucleate NAs within the lamellipodium. Subsequently, integrin complexes containing kindlin, but not talin, emerge. Once NAs have formed, myosin II activity promotes talin association with the integrin-kindlin complex in a stoichiometry consistent with each talin molecule linking two integrin-kindlin complexes.
[EX A]: yes

[EX Q]: Question: Is polymorphism Ala54Thr of fatty acid-binding protein 2 gene associated with stroke risk in Han population of Hunan China?
Answer: Our study shows that Ala54Thr of FABP2 may be not associated with stroke risk but associated with plasma TG level of stroke patients for Hunan Han population of China.
[EX A]: no

[EX Q]: Question: Does analysis of pulmonary function test result in a health check-up population?
Answer: Health check-up is an important approach for screening COPD, obstructive ventilator dysfunction, and obstructive small airway disease. Smoking cessation and controlling of relevant risk factors are helpful to lower the incidences of these conditions.
[EX A]:
yes
