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: Is increased expression of hyaluronic acid binding protein 1 correlated with poor prognosis in patients with breast cancer?
Answer: HABP1 might be an independent predictive factor for breast cancer prognosis and up-regulation of HABP1 might play an important role in the metastasis of breast cancer.
Example Output: yes

Example Input: Question: Does a protein complex containing Inscuteable and the Galpha-binding protein Pins orient asymmetric cell divisions in Drosophila?
Answer: Pins and Inscuteable are dependent on each other for asymmetric localisation in delaminated neuroblasts. The binding of Pins to Galpha protein offers the intriguing possibility that Inscuteable and Pins might orient asymmetric cell divisions by localising or locally modulating a heterotrimeric G-protein signalling cascade at the apical cell cortex.
Example Output: yes

Example Input: Question: Does ginsenoside Rd attenuate DNA Damage by Increasing Expression of DNA Glycosylase Endonuclease VIII-like Proteins after Focal Cerebral Ischemia?
Answer: Our results indicated that the neuroprotective function of GSRd for acute ischemic stroke might be partially explained by the up-regulation of NEIL1 and NEIL3 expressions.
Example Output:
yes
