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 pTEN loss in biopsy tissue predict poor clinical outcomes in prostate cancer?
Answer: PTEN loss at the time of biopsy seems to predict time to development of metastasis, prostate cancer-specific mortality and, for the first time, castration-resistant prostate cancer and response to androgen deprivation therapy after radical prostatectomy. If confirmed by larger studies, this would support the use of PTEN loss as an early marker of aggressive prostate cancer.

SOLUTION: yes

PROBLEM: Question: Is an absent pulse sensitive for the early detection of peripheral arterial disease?
Answer: Pulse palpation is not sensitive for the detection of PAD compared to ABI. More than two thirds of the patients within our cohort with PAD of either the left or right leg had a detectable pulse.

SOLUTION: no

PROBLEM: Question: Are cerebrospinal fluid corticotropin-releasing hormone levels elevated in monkeys with patterns of brain activity associated with fearful temperament?
Answer: These findings suggest that, in primates, the fearful endophenotype is characterized by increased fearful behavior, a specific pattern of frontal electrical activity, increased pituitary-adrenal activity, and increased activity of brain CRH systems. Data from other preclinical studies suggests that the increased brain CRH activity may underlie the behavioral and physiological characteristics of fearful endophenotype.

SOLUTION:
yes
