This answer claims that domesticating animals is "one of the first practices" a society must adopt to transition from hunting and gathering to agriculture. The argument does not need anything this broad or prescriptive. The argument needs a specific link between bovines, water, and domestication — not a general theory about the stages of societal development. The argument concludes these people were no longer exclusively hunter-gatherers based on the evidence of domesticated bovines; it does not need to establish that animal domestication is a prerequisite for leaving the hunter-gatherer stage. The word "must" makes this answer far too strong — the argument would survive even if some societies transitioned to agriculture without domesticating animals first.

This answer suggests that with human help, other large mammals could have inhabited the arid region. But the argument does not need to establish anything about what humans could have done with other animals. The argument's reasoning is: no other large mammals were present (fact), so there was no natural water (inference), yet bovines were present (fact), so bovines were domesticated (conclusion). Whether humans could have also helped other animals survive is irrelevant to this chain. The argument needs an assumption about why bovine presence without water implies domestication, not about the theoretical possibility of humans supporting other species.

This answer claims no human culture obtains food both through agriculture and through hunting and gathering. This is far too extreme. The argument concludes that these people were "no longer exclusively hunter-gatherers" — meaning they had added domestication to their repertoire. But the argument does not need to assume that agriculture and hunting are mutually exclusive. In fact, the conclusion's use of "exclusively" implies the opposite: these people may still have hunted and gathered but also practiced animal husbandry. The argument is perfectly compatible with cultures that combine agricultural and hunter-gatherer practices; it only claims these particular people were not limited to the latter.

This answer compares the water needs of domesticated versus wild animals of the same size. While this is a factual claim about animal biology, it does not address the argument's gap. The argument needs to know whether wild bovines could survive without natural water in an arid region — not whether domesticated bovines need less water than wild ones. Even if this comparison were true, it would not explain why the presence of bovines without natural water implies domestication. The key question is whether wild bovines require the same natural water sources that would attract other large mammals, not whether the domestication process itself changes water requirements.
