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: Are antihelminthic benzimidazoles novel HIF activators that prevent oxidative neuronal death via binding to tubulin?
Answer: These studies demonstrate that tubulin-binding drugs can activate a component of the hypoxic adaptive response, specifically the stabilization of HIF-1α and its downstream targets. Tubulin-binding drugs, including antihelminthic benzimidazoles, also abrogate oxidative neuronal death in primary neurons. Given their safety in humans and known ability to penetrate into the central nervous system, antihelminthic benzimidazoles may be considered viable candidates for treating diseases associated with oxidative neuronal death, including stroke.

Output: yes


Input: Consider Input: Question: Does tobacco smoking differently influence cell types of the innate and adaptive immune system-indications from CpG site methylation?
Answer: Studying cell type-specific methylation changes provides helpful information regarding the biological relevance of epigenetic modifications. Here, we could show that smoking differently affects both cells of the innate and adaptive immune systems.

Output: yes


Input: Consider Input: Question: Does implantation of different malignant human cell lines in an athymic mouse alter success and growth rates of either xenograft?
Answer: Implantation of Raji xenografts and HBT 3477 breast cancer xenografts in the same mouse did not affect xenograft success or growth rates, even when whole-body radiation of 4 Gy was used to promote Raji xenografts. These observations are not intended to imply an absence of differences in other biological parameters in this sytem or to encourage extrapolation of the conclusions indiscriminately to other preclinical models. Contrarily, our aim was to encourage other investigators to further validate these frequently used approaches.


Output: no
