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 ataxia Severity correlate with White Matter Degeneration in Spinocerebellar Ataxia Type 7?
Answer: These results suggest a significant contribution of local cerebellar and cerebellar-midbrain connections to ataxic impairment in spinocerebellar ataxia type 7. The results also suggest an involvement of cortical WM abnormalities including tracts within the occipital and frontal cortices. These findings contribute to a more comprehensive view of the clinical impact of the white matter degeneration in spinocerebellar ataxia type 7.
[EX A]: yes

[EX Q]: Question: Is cD10 useful to identify gastrointestinal contamination in endoscopic ultrasound-guided fine needle aspiration ( EUS-FNA ) cytology from pancreatic ductal adenocarcinoma?
Answer: As a loss of CD10 is a consistent feature of PDA, this marker can be useful, together with CEA, to aid the cytopathologist to identify neoplastic cells in a background rich in GI contaminant cells.
[EX A]: yes

[EX Q]: Question: Does apolipoprotein E genotype influence rates of cognitive decline in Alzheimer 's disease?
Answer: These results indicate that the mechanism placing individuals with an epsilon 4 allele at risk for developing AD does not influence the rate of cognitive decline. These observations imply that the influence of apoE epsilon 4 either precedes or occurs at an early point in the AD disease process.
[EX A]:
no
