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 race a predictor of prostate cancer detection on repeat prostate biopsy?
Answer: Race is not a predictor of prostate cancer detection in men undergoing repeat prostate biopsies. With the exception of HGPIN, all other clinical parameters were similar between black and white men. Serum PSA, PSA velocity, HGPIN and ASAP were found to be significant predictors of subsequent prostate cancer detection.

SOLUTION: no

PROBLEM: Question: Does greater body mass independently predict less radiographic progression on X-ray and MRI over 1-2 years?
Answer: Greater BMI is associated with a lower risk of progression on X-ray and MRI over 2 years. Subjects with greater BMI also demonstrate less bone oedema at baseline. Greater BMI may indicate a less aggressive RA phenotype and aid in risk stratification.

SOLUTION: yes

PROBLEM: Question: Does assessment of procedural skills using virtual simulation remain a challenge?
Answer: Only the full procedure of the LAP Mentor procedural simulator has enough discriminative power to claim construct validity. However, the lack of quality control, which is indispensible in the evaluation of procedural skills, makes it currently unsuited for the assessment of procedural laparoscopic skills. The role of the simulator in a training context remains to be elucidated.

SOLUTION:
yes
