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: Do traditional clinical risk assessment tools accurately predict coronary atherosclerotic plaque burden : a CT angiography study?
Answer: Coronary risk stratification using a risk factor only-based scheme is a weak discriminator of the overall atherosclerotic plaque burden in individual patients. Patients with little or no plaque might be subjected to lifelong drug therapy, whereas many others with substantial plaque might be undertreated or not treated at all.

Output: no


Input: Consider Input: Question: Is cD10 useful to identify gastrointestinal contamination in endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) cytology from pancreatic ductal adenocarcinoma?
Answer: As a loss of CD10 is a consistent feature of PDA, this marker can be useful, together with CEA, to aid the cytopathologist to identify neoplastic cells in a background rich in GI contaminant cells.

Output: yes


Input: Consider Input: Question: Does expression of p-AKT characterize adenoid cystic carcinomas of head and neck with a higher risk for tumor relapses?
Answer: Adenoid cystic carcinomas positive for p-AKT show a higher relapse risk. However, other parameters of glucose metabolism investigated here or proliferation (Ki67) were not predictive in this entity. Our findings demonstrate a possible background for therapeutic approaches targeting the inhibition of PI3K/AKT pathway.


Output: yes
