Which of the following, if true, would weaken the hypothesis advanced by Gnoske and Peterhans most?
Option (c)
The answer is (c). Gnoske and Peterhanssays that Tsavo lions may be similar to the unmaned cave lions of the Pleistocence. Then the 5th line in the 3rd paragraph says that Tsavo lions have a reputation of ferocity. So logically, the unmaned cave lions of the Pleistocence are ferocious. But option (c) says that the unmaned cave lions of the Pleistocence are shown to be far less violent than believed.
