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: Is variation in mortality among populations higher for pymetrozine than for imidacloprid and spiromesifen in Trialeurodes vaporariorum in greenhouses in Finland?
Answer: High variation in resistance levels to pymetrozine among populations within natural whitefly dispersal limits reflects variation in the usage of this compound among individual greenhouse crop producers. Thus, resistance management is recommended at the individual greenhouse crop producer level, even in a dense production cluster. © 2014 Society of Chemical Industry.

Ex Output:
yes


Ex Input:
Question: Is galectin-3 independently associated with cardiovascular mortality in community-dwelling older adults without known cardiovascular disease : The Rancho Bernardo Study?
Answer: Higher levels of galectin-3 are independently associated with all-cause and CVD mortality among community-dwelling older adults with no known CVD at baseline.

Ex Output:
yes


Ex Input:
Question: Does kupffer cell depletion by CI2MDP-liposomes alter hepatic cytokine expression and delays liver regeneration after partial hepatectomy?
Answer: We conclude that KCs are important for hepatocyte regeneration after PH. Delayed liver regeneration in KC-depleted rats can be explained, at least in part, by an imbalanced hepatic cytokine expression, thereby suppressing important growth-stimulating cytokines.

Ex Output:

yes
