Instructions: 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: Question: Are neuroprotective effects of enriched environment housing after transient global cerebral ischaemia associated with the upregulation of insulin-like growth factor-1 signalling?
Answer: Ultimately, these findings suggest the possibility that IGF-1 signalling may be one of the underlying mechanisms involved in the beneficial effects of EE in optimizing recovery following cerebral ischaemic injury.
Output:
yes
