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 novel individual metabolic profile characterize the protein kinase B-alpha ( pkbα-/- ) in vivo model?
Answer: Specific metabolic characterization should be assessed individually. Therefore, our in silico model enables novel insights inaugurating specific primary preventive strategies targeting individual metabolic profiling precisely.

Ex Output:
yes


Ex Input:
Question: Is serum Reg-Ialpha suitable marker of metabolic syndrome?
Answer: Our study, for the first time, indicates that serum Reg-1alpha is not useful for the diagnosis of metabolic syndrome (Tab. 3, Ref. 7).

Ex Output:
no


Ex Input:
Question: Does host resistance explain variation in incidence of male-killing bacteria in Drosophila bifasciata?
Answer: The absence of the infection from the Hokkaido population is not caused by failure of the male-killer to function on the Hokkaido genetic background.

Ex Output:

no
