Hi Experts,

Could you please provide your comments for subject-verb issue. what is the subject for second clause is it reason or the clause (What is much more difficult to determine)

Please clarify.
Thanks


The subject is "what is much more difficult to determine", and therefore singular verb "is" is correct.

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.


first sentence the subject is - period- verb has is correct


second clause starting with but- subject is - what is much more difficult to determine- the entire phrase so verb are is wrong as phrase is always singular
