Answer:
While parts (3) and (4) are accurate, parts (1) and (2) need revision.
Explanation:
The diversity of the African continent gives us a number of possible answers to the appearance of the first humans on the planet. Many scholars believe that the first humans came from this continent and not from Europe, so parts (1) and (2) need revision because they present incorrect information.
The population of the first humans lived from hunting and gathering, but over the years these people realized that farming would make their lives much easier, so they replaced the hunting-gathering system with agriculture, which led to increased production of food, laws, culture and disease. For this reason, we can conclude that parts (3) and (4) are accurate because they provide correct information.
