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 Q]: 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 A]: yes

[EX Q]: Question: Does developmental changes in spatial distribution of in vivo fluorescence and epidermal UV absorbance over Quercus petraea leave?
Answer: The spatial pattern of epidermal UV-screen over the area of oak leaves is related to leaf anatomy during development. In vivo spectroscopy and fluorescence imaging of the leaf surface showed the distribution of pigments within the leaf and hence can provide a tool to monitor optically the leaf development in nature.
[EX A]: yes

[EX Q]: Question: Do gold-induced reactive oxygen species ( ROS ) mediate suppression of monocytic mitochondrial or secretory function?
Answer: Our results do not indicate that ROS and redox effects play major roles in mediating the cytotoxicity of AF, GSTM or Au(III).
[EX A]:
no
