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: Are mannose-binding lectin polymorphisms associated with rheumatoid arthritis -- confirmation in two large cohorts?
Answer: MBL genotype groups are not associated with RA disease susceptibility or severity in this large study including a confirmation cohort. Compared with previous smaller studies these results add to more definite conclusions.

SOLUTION: no

PROBLEM: Question: Does implementing goal-directed protocols reduce length of stay after cardiac surgery?
Answer: A milestone-driven pathway supported by team rounding was associated with decreased lengths of CVICU and hospital stay. However, tracking patient trajectories by milestones suggests a more complex relationship than anticipated and presents new opportunities for SREBP implementation and research.

SOLUTION: yes

PROBLEM: Question: Is impaired subjective well-being in schizophrenia associated with reduced anterior cingulate activity during reward processing?
Answer: In patients with schizophrenia, reduced activation of the dACC during multiple aspects of reward processing is associated with lower SW. As the dACC has been widely linked to coupling of reward and action, and the link to SW is apparent over anticipation and outcome, these findings suggest that SW deficits in schizophrenia may be attributable to reduced integration of environmental rewarding cues, motivated behaviour and reward outcome.

SOLUTION:
yes
