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: Are c3 and C4 strongly related to adipose tissue variables and cardiovascular risk factors?
Answer: A strong relation between C3, C4 and C3a-desArg levels, adipose tissue and risk factors of CVD was established. The data support that the adipose tissue produces complement components and generates initiators of inflammation, such as C3a and C5a, able to trigger a cyto/chemokine response, in proportion to the amount of adipose tissue. This corroborates the concept that complement contributes to the low-grade inflammation associated with obesity.
[EX A]: yes

[EX Q]: Question: Do interictal epileptiform discharges have an independent association with cognitive impairment in children with lesional epilepsy?
Answer: Overall, IED effects on cognition were of a magnitude similar to lesional influences or drug effects (topiramate use). This study demonstrates an association between IEDs and cognitive dysfunction, independent of the underlying focal brain pathology.
[EX A]: yes

[EX Q]: Question: Does inhibition of Constitutive Nitric Oxide Synthase Influence Ventilation-Perfusion Matching in Normal Prone Adult Sheep With Mechanical Ventilation?
Answer: We found minimal or no influence of constitutive nitric oxide synthase inhibition by L-NAME on the distributions of ventilation and perfusion, and ventilation-perfusion in prone, anesthetized, ventilated, and healthy adult sheep with normal gas exchange.
[EX A]:
no
