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 the bradykinin B1 receptor antagonist BI113823 reverse inflammatory hyperalgesia by desensitization of peripheral and spinal neurons?
Answer: The selective bradykinin B1 receptor antagonist BI113823 reduces CFA-induced mechanical hyperalgesia which is mediated via antagonism of peripheral as well as spinal bradykinin B1 receptors. The selective modulation of CFA-sensitized spinal NS neurons by BI113823 could be a promising property for the treatment of inflammatory pain.
Example Output: yes

Example Input: Question: Do autism-associated gene Dlgap2 mutant mice demonstrate exacerbated aggressive behaviors and orbitofrontal cortex deficits?
Answer: Our findings clearly demonstrate that Dlgap2 plays a vital role in social behaviors and proper synaptic functions of the OFC. Moreover, these results may provide valuable insights into the neuropathology of autism.
Example Output: yes

Example Input: Question: Is wildtype epidermal growth factor receptor ( Egfr ) required for daily locomotor or masking behavior in mice?
Answer: Our results demonstrate that reduced EGFR activity alone is insufficient to perturb locomotor and masking behaviors in mice. Our results also suggest that other uncontrolled genetic or environmental parameters confounded previous experiments linking EGFR activity to daily locomotor activity and provide a cautionary tale for genetically uncontrolled studies.
Example Output:
no
