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.

Example Input: Question: Is increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines associated with risk of autism?
Answer: In this study of MCO members, increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines during the first 2 years of life was not related to the risk of developing an ASD.
Example Output: no

Example Input: Question: Is [ Sense of agency : experiencing judging ]?
Answer: The conception of the sense of agency has greatly evolved over the years, mainly because of the various experimental methods employed. The consequences of this are the various theoretical interpretations given to the characteristics of the sense of agency. They can be explained in two main points: a non-unified definition of the sense of agency and an absence of experimental data testing alternative interpretations. First, protocols using attribution judgements have proven to be useful to gain better understanding of the attribution mechanism in schizophrenia. However, findings obtained with these judgments have often been used to conclude on deficits of the sense of agency in schizophrenia, whereas the sense of agency is only a sub component of these judgements.
Example Output: no

Example Input: Question: Do prostaglandin D2 and leukotriene E4 synergize to stimulate diverse TH2 functions and TH2 cell/neutrophil crosstalk?
Answer: PGD2 and LTE4 activate TH2 cells through different pathways but act synergistically to promote multiple downstream effector functions, including neutrophil migration and survival. Combined inhibition of both PGD2 and LTE4 pathways might provide an effective therapeutic strategy for allergic responses, particularly those involving interaction between TH2 cells and neutrophils, such as in patients with severe asthma.
Example Output:
yes
