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 concomitant consumption of red wine and polyunsaturated fatty acids in edible oil influence the peroxidation status of chylomicron lipids despite increasing plasma catechin concentration?
Answer: Red wine consumption increases plasma catechins, but does not influence lipid peroxidation in postprandial CM.
Example Output: no

Example 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.
Example Output: yes

Example Input: Question: Do thinner needles influence injection pain , insulin leakage or bleeding in children and adolescents with type 1 diabetes?
Answer: We found no difference in injection pain, preference, bleeding or insulin leakage between the needles. Decreasing the needle diameter from 0.4 to 0.3 mm (27-30G) does not seem to decrease pain perception in this age group.
Example Output:
no
