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 mR spectroscopy indicate diffuse multiple sclerosis activity during remission?
Answer: The absence of early tissue atrophy and apparent axonal dysfunction (NAA loss) in these RR MS patients suggests that both are preceded by diffuse glial proliferation (astrogliosis), as well as possible inflammation, demyelination and remyelination reflected by elevated mI, Cho and Cr, even during clinical remission and despite immunomodulatory treatment.

Ex Output:
yes

Ex Input:
Question: Are higher rates of viral suppression with nonnucleoside reverse transcriptase inhibitors compared to single protease inhibitors explained by better adherence?
Answer: A higher proportion of individuals using NNRTI-based regimens had viral suppression when compared to those taking single-PI-containing regimens, and this association was not confounded by higher levels of adherence. These results suggest that improved viral suppression on NNRTI regimens compared to single-PI regimens is more closely associated with regimen potency than higher levels of adherence.

Ex Output:
no

Ex Input:
Question: Is myostatin expression altered by insulin deficiency and replacement in streptozotocin-diabetic rat skeletal muscles?
Answer: Muscle-specific myostatin expression is not increased under catabolic conditions in insulin-deprived diabetes. Insulin treatment also does not change myostatin transcript levels. The data provide the first assessment of potential interplay between insulin and myostatin and they do not support a major role of circulating insulin in the in vivo regulation of myostatin gene expression. A role of myostatin in muscle catabolism in chronic insulin-deprived diabetes is also not indicated by the current results.

Ex Output:
no
