Question ID:PT89 S2 Q7 Passage:Thousands of fossils from the long-extinct dire wolf have been found in a cluster of natural tar pits in which animals became trapped and were preserved for millennia. None of these fossils came from dire wolf pups under six months old. Pups under six months old, therefore, probably did not accompany adults that were scavenging or hunting. Stem:Which one of the following is an assumption required by the argument? Correct Answer Choice:DChoice A:Dire wolf pups under six months old would not have contributed to the adults' success in scavenging or hunting. Choice B:If a dire wolf pup under six months old became trapped in a tar pit, it would be better able to pull itself free than an adult dire wolf would. Choice C:Before the dire wolf became extinct, more dire wolves became trapped in the tar pits than did any other animal species. Choice D:The entrapment of dire wolves in the tar pits most frequently occurred when those animals were scavenging or hunting. Choice E:For the dire wolves that lived nearby, the tar pits were a favorite location for scavenging and hunting.
