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.

Input: Consider Input: Question: Is time-domain T-wave alternans strongly associated with a history of ventricular fibrillation in patients with Brugada syndrome?
Answer: Elevated time-domain TWA on AECG confirms arrhythmia risk in symptomatic BrS patients without the need for provocative stimuli.

Output: yes


Input: Consider Input: Question: Are levels of soluble CD30 in cord blood and peripheral blood during childhood correlated with the development of atopic disease or a family history of atopy?
Answer: These findings indicate that the sCD30 concentration in cord blood is not a reliable prognostic indicator of, nor a useful diagnostic marker for, atopic disease in children up to 7 years of age. If such correlations do exist, they might be masked by age-dependent variations in the circulating levels of sCD30, which may reflect individual differences in the maturation of children's immunological responses.

Output: no


Input: Consider Input: Question: Do detailed characterization of tumor infiltrating lymphocytes in two distinct human solid malignancies show phenotypic similarities?
Answer: This study demonstrates that multi-color flow cytometry of freshly digested tumor samples reveals phenotypic differences in TIL vs PBL T cell sub-populations. The TIL composition in primary and metastatic tumors from two distinct histologies were remarkably similar, showing a greater proportion of activated/suppressive Treg (HLA-DR(+), CD39(+), CTLA-4(+) and Helios(+)) and activated cytotoxic T cells (CD8(+)/HLA-DR(+)/CD38(+)) when compared to PBL and an increase in IL-6 mRNA from CD4 TIL.


Output: yes
