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: Does bisphenol A increase atherosclerosis in pregnane X receptor-humanized ApoE deficient mice?
Answer: These findings identify a molecular mechanism that could link BPA exposure to increased risk of CVD in exposed individuals. PXR is therefore a relevant target for future risk assessment of BPA and related environmental chemicals in humans.

Output: yes

Input: Consider Input: Question: Is alloantigen-driven T cell death mediated by Fas ligand and tumor necrosis factor-alpha essential for the induction of allograft acceptance?
Answer: These data indicate that: (1) FasL and TNFalpha expression are not obligatory for the induction of long-term allograft acceptance by CTLA4Ig and (2) FasL- and TNFalpha-independent death pathways contribute to alloantigen-driven T cell apoptosis.

Output: no

Input: Consider Input: Question: Does serotonin enhance platelet procoagulant properties and their activation induced during platelet tissue factor uptake?
Answer: Serotonin enhances the interaction of platelets with TF-MVs, increases platelet activation, and potentiates their overall procoagulant activity. The present results could have significant implications in thrombus formation and in the thrombogenic profile of pathological situations with increased cardiovascular risk.
Output: yes
