Hi Ellen,
Thanks for your response--strictly speaking, this is not really conditional reasoning; distance and group size do correlate with diet. And diet is affected by the shape of teeth and face--this is a fact--it is not a necessary condition (in other words, we couldn't say "distance and group size correlate with diet, only if diet depends on the shape of teeth and face").
I would be hesitant to use arrows here, because in this fairly unique case we are dealing with correlations. Distance and group size correlate with diet, and diet correlates with shape of face and teeth. Therefore, as answer choice E provides, information about shape of face and teeth can provide likelihoods about whether an animal lived in herds.
I hope that's helpful--please let me know whether this is clear--thanks!
