@shafieiava,

Happy to help.

(B) says, "The caves in which the highly polished flints were found
are unadorned by cave paintings."

The problem with (B) is that a dearth of cave paintings does not
necessarily mean that cave dwellers didn't care at all about
aesthetics. It's possible that the polished flints provided the cave
dwellers with the amount of beauty they wanted. As a result, we can
get rid of this choice.

(D) says, "Flints were often used by early humans for everyday chores
other than hunting."

(D) tells us that the flints are used for things other than simply
hunting. And it's possible that one of those chores could be the
reason that the flints were polished, just as it's possible that they
could've been polished for aesthetic purposes. (D) casts doubt on the
conclusion of the argument by introducing an alternative explanation,
so it weakens the argument and is the right answer.

Does this answer your question? Let us know if you have any other questions!

Another possibility for there being no cave paintings is that we don't know if the early humans actually resided in the caves where the flints were found. It could be that the humans were simply staying in those caves temporarily when something happened and they had to leave the flints there. Perhaps there were many cave paintings in other caves.
