Running a group or a hospital, unfortunately, requires significant bureaucracy. The doctors are needed to make that run, which means taking responsibility for the clerical drudgery involved. This means attending meetings--lots of meetings. And they're always at night or during office hours, which can cut into your income. Note that the question doesn't ask whether your attendance will be good, but how it has been in the past. This implies that your answer may be verified by a phone call or two, so tell the truth. (Most likely, no one will be checking up on your answer, so even if you've been truant in the past, pledge to do better.)
