Passage Summary: These deer have stomachs that can't handle meat at all, but they've been caught red-handed killing and snacking on turtles.

Reasoning: Sambar deer are biologically unable to digest meat, yet they have been observed killing and eating box turtles.

Analysis: We are faced with a biological paradox: why would an animal eat something it cannot digest? To resolve this, we need a piece of information that explains the benefit of this behavior without requiring the deer to actually digest the meat for calories. Perhaps the deer are after the calcium in the turtle shells, or maybe they are seeking a specific mineral not found in plants. Look for an answer that provides a motivation for the 'eating' that doesn't involve meat digestion.
