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: Does propofol induce pulmonary dysfunction in stressed endotoxic pigs receiving Intralipid?
Answer: Small doses of endotoxin, when given to pigs, induce major perturbations of cardiopulmonary function. Neither Intralipid, high vs. low dose, nor diisopropyl phenol, at sedating vs. anesthetizing doses, worsened the physiologic derangement associated with the stress of low-dose endotoxemia.

Ex Output:
no

Ex Input:
Question: Is epithelium-dependent bronchodilatory activity preserved in pig bronchioles after normothermic cardiopulmonary bypass?
Answer: Normothermic cardiopulmonary bypass does not result in epithelial dysfunction in pigs. Epithelium-dependent and epithelium-independent bronchodilators may be equally effective before and after cardiopulmonary bypass.

Ex Output:
yes

Ex Input:
Question: Does silencing the porcine iGb3s gene affect Gal3Gal levels or measures of anticipated pig-to-human and pig-to-primate acute rejection?
Answer: Our data suggest that iGb3s is not a contributor to antibody-mediated rejection in pig-to-primate or pig-to-human xenotransplantation. Although iGb3s gene silencing significantly changed the renal glycosphingolipid profile, the effect on Gal3Gal levels, antibody binding, and cytotoxic profiles of baboon and human sera on porcine PBMCs was neutral.

Ex Output:
no
