Explanation:

The first Agricultural Revolution took place during the Neolithic period (12,000 years ago) as technologies and techniques for agriculture improved and this allowed agriculture to become an essential part of first societies. Indeed, the agricultural revolution was possible because human societies developed different tools and techniques that allowed people to have control over the process of growing plants. Also, canals and wells were created to irrigate crops, which made it possible to cultivate in areas that were not necessarily close to rivers or water sources. Finally, all of this made possible the growth of cities and human settlements as people could rely on crops rather than migrate to get food. Thus, the three characteristics of this revolution are new tools (Option C), creation of canal and wells (Option E), and larger settlements (Option B).
