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 tRAIL receptor deletion in mice suppress the inflammation of nutrient excess?
Answer: These data advance the concept that macrophage-associated hepatic and adipose tissue inflammation of nutrient excess requires TR signaling.
Example Output: yes

Example Input: Question: Is the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.
Example Output: no

Example Input: Question: Is esophageal carcinoma cell line with high EGFR polysomy responsive to gefitinib?
Answer: We show for the first time a significant treatment response to the EGFR tyrosine kinase inhibitor gefitinib in esophageal tumor cells with a high polysomy for EGFR, suggesting a future role of anti-EGFR therapy for esophageal adenocarcinoma patients with a high EGFR polysomy.
Example Output:
yes
