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: Do human umbilical cord-derived mesenchymal stem cells protect against experimental colitis via CD5 ( + ) B regulatory cells?
Answer: HUC-MSCs protected against experimental colitis by boosting the numbers of CD5(+) B cells and IL-10-producing CD5(+) Bregs, and correcting Treg/Th17/Th1 imbalances.

Ex Output:
yes


Ex Input:
Question: Do expanded effector memory T-lymphocytes in DBA/2 mice inhibit the growth of SL2 tumours?
Answer: SL2 tumours induce expansion of effector memory lymphocytes in DBA/2 mice. However, expanded effector memory lymphocytes do not inhibit the growth of tumours.

Ex Output:
no


Ex Input:
Question: Are nonsense mutations in BAG3 associated with early-onset dilated cardiomyopathy in French Canadians?
Answer: Screening an extended panel of 41 candidate genes allowed us to identify probable pathogenic mutations in 69% of families with DCM in our cohort of mostly French-Canadian patients. We confirmed the prevalence of TTN nonsense mutations in DCM. Furthermore, to our knowledge, we are the first to present an association between nonsense mutations in BAG3 and early-onset DCM.

Ex Output:

yes
