Choose the selection from the introduction [paragraphs 1-5] that MOST suggests that tools give clues about how early humans interacted with each other.
A
Early humans did not leave behind written records for historians to study. Researchers do their best to learn about the beginnings of our species using clues that can still be found many thousands of years later.
B
Recently, a new batch of stone tools was discovered. Researchers studying them say they can tell us a great deal about how early humans developed. In particular, the evidence suggests that ancient humans used to build relationships with other groups in different places.
C
Scientists cannot be sure whether the objects were made by members of our species, known as Homo sapiens. If not, the tools might have been made by a relative of Homo sapiens that has since died off.
D
It is certainly possible that the tools were made by Homo sapiens, though. They are about 320,000 years old, which is just a bit older than the earliest known Homo sapien fossils. They were found in Morocco in 2017.
