Ok so the challenge that early farmers did not face as a result of the change from a nomadic lifestyle to an agricultural lifestyle could be early death caused by disease. Because in agricultural lifestyle, the nomads are now trying to establish a boundary between their food to eat and food to sell or exchange. It could also be a challenge for them to clear and cultivate lands because of the lack of resources.

They didn't face D, they could have died just as easily with a nomadic lifestyle.
