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.

Input: Consider Input: 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.

Output: no


Input: Consider Input: Question: Is 14-3-3η a novel mediator associated with the pathogenesis of rheumatoid arthritis and joint damage?
Answer: Extracellular 14-3-3η activates key signalling cascades and induces factors associated with the pathogenesis of RA at concentrations found in patients with RA, and its expression is higher in patients with radiographic damage and RA progression.

Output: yes


Input: Consider Input: Question: Does rush immunotherapy for wasp venom allergy seem safe and effective in patients with mastocytosis?
Answer: VIT is safe in cutaneous mastocytosis patients with WA, while caution has to be made in case of systemic mastocytosis. VIT was effective in the patients who were re-stung.


Output: yes
