PT 65 S4 Q23 *SPOILER* IF you haven't taken test Forum

This question has had me stumped for like 3 days! I have done everything I can to wrap my head around it, but it just doesn't seem to want to click for me. So, is there anyone out there that may be able to help me understand why the correct answer is correct, I basically ruled all the answers out and guessed (E), but can see why its wrong after the fact. It is a most strongly supported question.

The question begins with background: Dogs are descendants of domesticated wolves.

Premise: It has recently been found that some dogs are much more closely related genetically to wolves than to most other breeds of dogs.

Conclusion: This shows that some dogs are descended from wolves that were domesticated much more recently than others.

(B) starts off telling us that we are talking about the dogs more closely related to wolves than to other dogs (so thats good), it finishes with the former breed (the ones we need) has more recent undomesticated ancestors than the latter breed has.

For simplicity, lets call the dogs that are from wolves domesticated more recently, Group A. The other dogs = Group B

I ruled (B) out right off the bat because of the UNDOMESTICATED. I thought that was to an inference that was to far out of scope. Next, the stem tells us that the dogs in group A come from wolves domesticated more recently than the wolves Group B is related to. But, based on this how can we infer which group has more recent undomesticated ancestors?

I don't know what I am overlooking for this not to make sense. Hopefully someone can clear this up for me. Thanks in advance!

Because if the wolf ancestors were domesticated more recently, then they remained undomesticated longer.

Don't sweat it! This question took me forever to solve -- I eliminated B on the first pass for the same reason. I was so tempted to choose A, but it reverses the logic of the stimulus, taking the conclusion as a sufficient condition.
