The exact year when the Mogao caves in Dunhuang, China began to be sculpted and chiseled by the Northern Wei Dynasty has been difficult to verify, but what is much easier to determine are the purpose of their existence, the religious significance that the drawings on the walls of the caves held, and the order in which the caves were constructed.

A has been difficult to verify, but what is much easier to determine are
B has been difficult to verify, but what is much easier to determine is
C have been difficult to verify, but what is much easier to determine is
D have been difficult to verify, but what is much easier to determine are
E are difficult to verify, but that which is much easier to determine is

A and B are the contenders, due to the 'has' SVA ......

A seems appropriate since the 'are' is being used for three things connected by 'and'

Hence A

OA please?

imo "B".
because"what is much easier to determine " is the subject of a clause. and a complete clause is always singular whenever we consider it as a subject. similar question from OG 11.

I think I will have to agree with you. The 'ear' wanted to go with B but 'is' in 'what is' threw me off since I thought that 'is' covers for 'what is much easier to determine' but yours is more robust logic.

The 'is' in 'what is much easier' agrees with 'what' and the second 'is' agrees for the whole clause 'what is much easier to determine'

Cheers

ehhh, dunit to waste the expert time here,,,,hehehehhe let me! lol ( kidding)

we can eliminate C, D, E because the subject " exact year" is single noun so it does need a single verb ( clearly?)
and we can eliminate A because the ST is listing stuffs, things, so what is the subject here, not the stuffs listed in the ST (clearly?)
so the answer is B

D have been difficult to verify, but what is much easier to determine are
E are difficult to verify, but that which is much easier to determine is
Quickest approach:

In C, D and E, have been and are should be singular to match the singular subject year. Eliminate C, D and E.

In A, the pronoun what is the subject both of is (singular) and of are (plural). While what can be singular or plural, it cannot be both at the same time. Eliminate A.

The correct answer is B.

Hi Mitch,
Isnt B an example of an inverted sentence where the subject follows the verb "is"
so we can write

"the purpose of their existence, the religious significance that the drawings on the walls of the caves held, and the order in which the caves were constructed are what is much easier to determine"

"the purpose of their existence, the religious significance that the drawings on the walls of the caves held, and the order in which the caves were constructed is what is much easier to determine"

"the purpose of their existence, the religious significance that the drawings on the walls of the caves held, and the order in which the caves were constructed are what are much easier to determine"

"the purpose of their existence, the religious significance that the drawings on the walls of the caves held, and the order in which the caves were constructed are what are much easier to determine"
The basic structure of the sentences above is X is Y. The subject of each of these sentences is X. The order matters:

What is easier to determine is the purpose...the significance...and the order. (subject = what, verb = is)

The purpose, the significance...and the order in which the caves were constructed...are (subject = purpose, significance and order, verb = are)

In an inverted sentence, no subject appears before the verb:

Inside the room were a bed and a table.


In the sentence above, no subject precedes the verb were, so it's clear that the bed and the table form the subject.
