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 early primary repair of tetralogy of Fallot lead to increased postoperative resource utilization?
Answer: Extracardiac anomalies, prematurity, low birth weight, and nonelective surgical intervention are predictors of increased morbidity and increased hospital resource utilization and impose a significant cost burden to the care of these patients. Early primary repair of tetralogy of Fallot can be safely performed without any increase in morbidity or increased hospital resource utilization.
Example Output: no

Example Input: Question: Does eHD3-dependent endosome pathway regulate cardiac membrane excitability and physiology?
Answer: These data provide new insight into the critical role of endosome-based pathways in membrane protein targeting and cardiac physiology. EHD3 is a critical component of protein trafficking in heart and is essential for the proper membrane targeting of select cellular proteins that maintain excitability.
Example Output: yes

Example Input: Question: Are equine mesenchymal stromal cells and embryo-derived stem cells immune privileged in vitro?
Answer: Equine MSCs and ESCs possess a degree of innate immune privilege, and MSCs secrete soluble factors that suppress PBMC proliferation and alter cytokine expression. These properties may make possible the future clinical use of allogeneic stem cells to help standardize and broaden the scope of treatment of tissue injuries.
Example Output:
yes
