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: Is herpes simplex virus type 1 transcription detectable in quiescent human stromal keratitis by in situ hybridization?
Answer: At the level of detection afforded by in situ hybridization, HSV persistent in scarred human corneas after stromal keratitis appears to be transcriptionally dormant. This contrasts with the situation in neurons of latently infected sensory ganglia, in which LATs are present at high levels.

Ex Output:
no

Ex Input:
Question: Does frailty predict major bleeding within 30days in elderly patients with Acute Coronary Syndrome?
Answer: Frailty phenotype, as a marker of biological vulnerability, is an independent predictor of major bleeding in elderly patients with ACS. Frailty can play an important role in bleeding risk stratification and objective indices should be integrated into routine initial evaluation of these patients.

Ex Output:
yes

Ex Input:
