Hi all,
In my 2 cents,
"including" can be used to illustrate a list of items.In the construction of option E,it seems like "flint cores" are examples of "the earliest known tool";hence,the meaning is alter.
ps I did google and find that "flint core" is more likely raw material;hence option C is better.
