TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: yes

PROBLEM: Question: Is kREX2 essential for either procyclic or bloodstream form Trypanosoma brucei?
Answer: KREX2 is a U-specific exonuclease that is dispensable for RNA editing in vivo in T. brucei BFs and PFs. This result suggests that the U deletion activity, which is required for RNA editing, is primarily mediated in vivo by KREX1 which is normally found associated with only one type of editosome. The retention of the KREX2 gene implies a non-essential role or a role that is essential in other life cycle stages or conditions.

SOLUTION: no

PROBLEM: Question: Is planimetry of aortic valve area using multiplane transoesophageal echocardiography a reliable method for assessing severity of aortic stenosis?
Answer: Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.

SOLUTION:
no
