Why did some choose to continue hunting and gathering even as agriculture developed?

Explanation:Historians have several theories about why many societies switched from hunting and foraging to settled agriculture. One of these theories is that a surplus in production led to greater population. Not everyone needed to be focused on food production, which led to specialization of labor and complex societies.

seeing as no choices were provided, i'll do my best to answer it from knowledge.

job specialization promotes work ethic to the person doing the job. he/she may be strong in the arms and able to lift things, specializing him/her in a job where you lift and carry.
