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: Do clinical and radiological courses differ between fluid-attenuated inversion recovery-positive and negative patients with stroke after thrombolysis?
Answer: Visibility of lesions on FLAIR in areas of diffusion restriction was not predictive of the response to thrombolysis.

Output: no


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 a negative nontreponemal and/or specific antitreponemal IgM test exclude active infectious syphilis : evidence from a rabbit infectivity test : A case report?
Answer: The definitive differential diagnosis of active infectious syphilis should be reconsidered. Moreover, selecting the appropriate penicillin preparation is important because T pallidum can reside in sequestered sites. It is necessary to treat a patient with known invasion of the central nervous system with aqueous crystalline penicillin G, if previous treatment for syphilis failed and patients had some clinical neurological presentation that is otherwise unexplained, but that could represent neurosyphilis. Additional studies are needed to confirm the results in other syphilis patients.


Output: no
