I did answer tacitly -- I called the question "rhetorical." Group A will be more viable. That's obvious.
But the implication of your question is that Group B is likely to have existed. I have rebutted that point. If that isn't the implication of your question, your question isn't indicative of anything, and it's an entirely theoretical exercise.
You are totally wrong. Group B not only existed, but you and I descended from it.
The question really is how much do people value curiosity?
Close. Some curiosity is clearly related to survival, e.g., it there food in the valley, is their a predator behind the next hill. I'm interested in "metaphysical" curiosity.
Yes but some to to gain knowledge.
