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).
