Ex Input:
Question: Do simple counts of ADL dependencies adequately reflect older adults ' preferences toward states of functional impairment?
Answer: Our results suggest that the count of ADL dependencies does not adequately represent the utility for a health state. Cost-effectiveness analyses and other evaluations of programs that prevent or treat functional dependency should apply utility weights rather than relying on simple ADL counts.

Ex Output:
no

Ex Input:
Question: Do veteran athletes exercise at higher maximum heart rates than are achieved during standard exercise ( stress ) testing?
Answer: Maximal HR in veteran athletes during specific sporting activities was significantly higher than that attained during a routine sECG. This finding was not sport-specific, nor was it related to the level of competitiveness of the trial participants. These data show that a routine sECG is a submaximal test of exercise performance, and should be interpreted as such.

Ex Output:
yes
