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 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 transcriptome analysis of proton pump inhibitor-responsive esophageal eosinophilia reveal proton pump inhibitor-reversible allergic inflammation?
Answer: These findings provide definitive evidence that PPI-REE is a disease entity with significant molecular overlap with EoE, suggesting that many patients with PPI-REE represent a continuum of the same pathogenic allergic mechanisms that underlie EoE and thus might constitute a subphenotype of patients with EoE. The ability of PPI therapy to nearly entirely reverse gene expression associated with PPI-REE, particularly that associated with classic features of allergic inflammation, provides new insight into potential disease etiology and management strategies for patients with significant esophageal eosinophilia.

Output: yes


Input: Consider Input: Question: Does a focal cryogenic brain lesion reduce the minimum alveolar concentration for halothane in rats?
Answer: These results indicate that a focal cortical brain injury that has no obvious neurologic or behavioral effects in the awake rat does not alter halothane requirements.


Output: no
