Response to selection criteria regarding health and wellbeing
The existence of such a question implies to me that the university, or perhaps just the department, has made some commitment to advancing human health and wellbeing. Perhaps this is a shared goal of many (most?) of the existing faculty. 

The question may or may not be one that will be decisive in choosing a candidate. But it seems to be asking whether your personal goals are in alignment with that shared goal. 

Perhaps you have thought of this sort of thing in the past, and perhaps your natural inclination is to support it. But it is also possible that you've never considered it and think it is irrelevant. I doubt that anyone would be likely to actively oppose it, however. 

But, I always suggest that you answer honestly. Even if your answer is just "I'll have to think about that for a while as the question hasn't come up before" it could be enough. Answering "Stupid, Stupid, STUPID." won't get you the job, I think. And if that is, in fact, your first thought, then you might not be a good fit with the others, even if you get the job. 

I find the question thought provoking, if nothing else. In some fields, it is an important question also - medical fields, for example. In CS and mathematics it is a bit more speculative. 

But even in AI, a commitment to "do no harm" is worth the effort it takes. Some machine learning algorithms have proven problematic in the recent past, having been trained on a too-narrow or even racist base.
