Question

as far as i know, nobody has ever been eaten by a black hole, but there is compelling evidence to suggest that black holes in the universe routinely dine upon wayward stars and unsuspecting gas clouds. as a cloud approaches a black hole, it hardly ever falls straight in.... as the cloud layers spiral closer to the event horizon they heat up, from internal friction, to upwards of a million degrees -- much hotter than any known star. the gas glows blue - hot as it becomes a copious source of ultraviolet and x - ray energy. what started as an isolated, invisible black hole (minding its own business) has select the message that most accurately fits the passage. black holes are huge but incredibly hard to locate. black holes are incredibly powerful cosmic forces. black holes consume much more than just humans. black holes prefer to mind their own business. retry

Explanation:

The passage emphasizes that black holes in the universe "routinely dine upon wayward stars and unsuspecting gas clouds", which means they consume more than just humans (as the option "Black holes consume much more than just humans" suggests). The other options are not supported: there's no mention of black holes being hard to locate or being "powerful cosmic forces" in a general sense (the focus is on their consumption behavior), and "Black holes prefer to mind their own business" is contradicted by the description of them interacting with gas clouds etc.

Answer:

Black holes consume much more than just humans.
