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.

Ex Input:
Question: Does [ Histology accurately predict the clinical behaviour of bronchopulmonary carcinoids - results from an Icelandic population-based study ]?
Answer: BPCs usually behave as benign neoplasms, with excellent long-term survival after surgical removal. Metastases are more common in patients with atypical histology (40%), and their survival is worse. However patients with typical histology can metastasize (14.8%) and die from the disease. Therefore, histology (typical vs. atypical) can not be used with certainty to predict the clinical behaviour of these tumors.

Ex Output:
no


Ex Input:
Question: Does cSTMP induce apoptosis and mitochondrial dysfunction in human myeloma RPMI8226 cells via CHOP-dependent endoplasmic reticulum stress?
Answer: Our results indicated that CSTMP could induce apoptosis and mitochondrial dysfunction in RPMI8226 cells via CHOP-dependent ER stress.

Ex Output:
yes


Ex Input:
Question: Does recombinant kringle 1-3 of plasminogen inhibit rabbit corneal angiogenesis induced by angiogenin?
Answer: Recombinant kringle 1-3 appears to inhibit angiogenin-induced angiogenesis in a rabbit corneal pocket assay. Recombinant kringle 1-3 may have therapeutic potential as an antiangiogenic agent.

Ex Output:

yes
