some questions again, from 987
        The period when the great painted caves at Lascaux and Altamira were occupied by Upper Paleolithic people has been established by carbon-14 dating, but what is much more difficult to determine are the reason for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals.

the answer is B and the explanation here is "what is-but" but I think the subject of the but sentence should be the reason and why not reasons here? for their decoration, the use to which primitive people put the caves, and the meaning of the magnificently depicted animals. they're all reasons right?
