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: Does growth hormone ( GH ) treatment restore endothelial function in children with GH deficiency?
Answer: These results indicate that endothelial function is impaired in children with GHD. GH therapy does not restore the impairment.
Example Output: no

Example Input: Question: Do workers of a drywood termite work?
Answer: Thus, in contrast to general perception where termite workers are considered equivalent to workers in Hymenoptera, the 'large immatures' of C. secundus did not behave as workers that help in raising younger siblings. This apparently is not necessary as the colony lives inside its food. These results, which are likely to be typical for wood-dwelling termites, open the possibility that large complex group living can evolve without altruistic helping and that costly altruistic helping by workers in termites evolved only as a second step.
Example Output: no

Example Input: Question: Does blood PGC-1α Concentration predict Myocardial Salvage and Ventricular Remodeling After ST-segment Elevation Acute Myocardial Infarction?
Answer: Baseline PGC-1α expression and an attenuated systemic response after acute myocardial infarction are associated with greater myocardial salvage and predict less ventricular remodeling.
Example Output:
yes
