In the central Amazon basin, sediment deposits more than sixteen million years old consist of clays formed from rocks found in the basin itself. But the sediment deposits sixteen million years old or younger also include dark sand resembling rocks found in the Andes mountain range. These observations have led geologists to conclude that around sixteen million years ago, rivers in the Andes first began to drain into the central Amazonbasin.
The geologists have concluded thefollowing:
around sixteen million years ago, rivers in the Andes first began to drain into the central Amazonbasin
The passage mentions some evidence that supports thatconclusion:

We see that the reasoning of the argument is basically
