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: Do dual inhibition of nuclear factor kappa-B and Mdm2 enhance the antitumor effect of radiation therapy for pancreatic cancer?
Answer: Combination therapy of radiation with nafamostat mesilate exerts enhanced anti-tumor effect against human pancreatic cancer.
Example Output: yes

Example Input: Question: Are screening tests enough to detect hemineglect?
Answer: Hemineglect may not be recognized with single screening tests commonly used. The use of a standard battery is recommended to improve diagnostic sensitivity in individuals with various subtypes of hemineglect.
Example Output: no

Example Input: Question: Does alternaria induce Production of Thymic Stromal Lymphopoietin in Nasal Fibroblasts Through Toll-like Receptor 2?
Answer: The results of this study show that TSLP expression could be induced in nasal fibroblasts by exposure to Alternaria and that TLR2 may be involved in the process. The promotion of TSLP production in nasal fibroblasts by airborne fungi may facilitate the development or exacerbation of Th2-type nasal inflammation, especially in CRS with nasal polyps.
Example Output:
yes
