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 high salt intake associated with a higher risk of cardiovascular events : a 7.2-year evaluation of a cohort of hypertensive patients?
Answer: In a cohort of hypertensive patients, high salt intake independently predicts the occurrence of CV events, particularly of stroke.

Output: yes

Input: Consider Input: Question: Does discovery-based protein expression profiling identify distinct subgroups and pathways in leiomyosarcomas?
Answer: These results suggest that UPS tumors share a similar lineage as leiomyosarcomas and are likely to originate from different stages of differentiation from mesenchymal stem cells to smooth muscle cells.

Output: yes

Input: Consider Input: Question: Does recipient T cell TIM-3 and hepatocyte galectin-9 signalling protect mouse liver transplants against ischemia-reperfusion injury?
Answer: Harnessing TIM-3/Gal-9 signalling at the T cell-hepatocyte interface facilitates homeostasis in IR-stressed orthotopic liver transplants. Enhancing anti-oxidant hepatocyte Gal-9 potentiates liver IR-resistance. Negative regulation by recipient TIM-3+CD4+ cells provides evidence for cytoprotective functions of a discrete T cell subset, which should be spared when applying T cell-targeted immunosuppression in transplant recipients.
Output: yes
