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: Is pre-surgical cortical activation to food pictures associated with weight loss following bariatric surgery?
Answer: We found that neural activity in previously established regions associated with cognitive and behavioral self-regulation predicts weight loss following bariatric surgery. These preliminary findings highlight the role of neural circuitry in the success and maintenance of weight loss and suggest a possible future use of fMRI in screening LAGB surgery candidates.

SOLUTION: yes

PROBLEM: Question: Is polymorphism Ala54Thr of fatty acid-binding protein 2 gene associated with stroke risk in Han population of Hunan China?
Answer: Our study shows that Ala54Thr of FABP2 may be not associated with stroke risk but associated with plasma TG level of stroke patients for Hunan Han population of China.

SOLUTION: no

PROBLEM: Question: Is [ A single positive prostatic biopsy out of six systematic biopsies correlated with the intracapsular nature of the tumor on an individual level ]?
Answer: A single positive prostatic biopsy out of six systematic biopsies is a useful predictive factor of local extension, but, in the individual patient, does not guarantee favourable histopathological characteristics of the tumour, nor a favourable course of the disease.

SOLUTION:
no
