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 alpha-2 adrenoreceptors probably mediate the immobility produced by inhaled anesthetics?
Answer: Although stimulation (agonism) of alpha-2 adrenoreceptors can decrease the inhaled anesthetic concentration required to produce immobility in the face of noxious stimulation, blockade of alpha-2 adrenoreceptors minimally affects the concentration. Thus, augmentation of the effect of alpha-2 adrenoreceptors is not an appreciable part of the mechanism whereby inhaled anesthetics produce immobility.
[EX A]: no

[EX Q]: 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 A]: yes

[EX Q]: Question: Does a yearlong exercise intervention decrease CRP among obese postmenopausal women?
Answer: A moderate-intensity exercise intervention reduced CRP for 12 months among women who were obese at baseline. These findings support the role of exercise in modulating inflammatory processes that are related to increased risk of chronic disease among obese women.
[EX A]:
yes
