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: Is early systemic sclerosis : serum profiling of factors involved in endothelial , T-cell , and fibroblast interplay marked by elevated interleukin-33 levels?
Answer: Our study suggests that an endothelial, T-cell and fibroblast activation can be present in patients with early SSc and it is associated with a distinct profile of circulating factors involved in the cross-talk of these cells. The marked increase of IL-33 in early SSc patients suggests new routes of investigation of cell-cell dynamics in target tissues predating overt disease manifestations, thus opening to new therapeutic approaches.

Output: yes


Input: Consider Input: Question: Does prolonged hemorrhagic shock impair regeneration of plasma coagulant masses in the rabbit?
Answer: Dilutional coagulopathy corrects spontaneously within hours. Normovolemic shock prolongs dilutional coagulopathy not by impairment of factor regeneration but because of further (internal) dilution due to plasma expansion. Rapid correction of dilutional coagulopathy is likely to necessitate cryoprecipitate administration.

Output: no


Input: Consider Input: Question: Does a Randomized Trial of Expanding Choice set to Motivate Advance Directive Completion?
Answer: These results suggest that although an expanded choice set may initially nudge patients toward completing advance directives without restricting choice, increasing actual completion requires additional interventions that overcome downstream barriers.


Output: yes
