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 discovery-based protein expression profiling identify distinct subgroups and pathways in leiomyosarcomas?
Answer: These results suggest that UPS tumors share a similar lineage as leiomyosarcomas and are likely to originate from different stages of differentiation from mesenchymal stem cells to smooth muscle cells.
Example Output: yes

Example Input: Question: Is pKCε a negative regulator of PVAT-derived vessel formation?
Answer: PKCε negatively interferes with vessel progenitor differentiation via interaction with PAK-1.
Example Output: yes

Example Input: Question: Is ascaris lumbricoides-induced interleukin-10 associated with atopy in schoolchildren in a rural area of the tropics?

Example Output:
no
