Because according to Ron Purewal, Option D is wrong. In his discussion, option A is the right option but Gmat Prep software mentions option D as the right option. So as per the experts, its 1-1 between options A and D. Now this is something in which I think a third expert's opinion is required.

Now read what you have mentioned:

what is much more difficult to determine (IMO, this is not the subject. Listen to Ron Purewal's first video on Compound Subject, Actually this ques is discussed there)

3.(is the use to) which primitive peoples put the caves
(is the use to) the reason for their decoration
and (is the use to) the meaning of the magnificently depicted animals.

IMO D is wrong. Need an expert to answer this question.

@ABI: if u check option A : If its right then , you must have to tell the subject of that Aux verb "ARE"
Manhattan says : Clause may behave as singular subject .....IF official ans given by "GMAC" , then we must have to belive ...because most of the other sources are based on this official sources on ...

As mentioned in the spoiler, what i feel is that its a backward construction, so the subject for this clause is
"the use to which primitive peoples put the caves, the reason for their decoration, and the meaning of the magnificently depicted animals"

Plus, GMAC had made mistakes in the past, so grammar wont change because of these mistakes. So I need some help in this regard. You are right, clauses can act as Singular Subject, but the clause mentioned in this case IMO can't act as a subject.

consider the example:

What is placed on the table is pen, pencil and paper.
What is placed on the table are pen, pencil and paper.

What do you think which one is right?

The other doubt i have is "What is placed....." vs "What are placed....". Dont know which one is the correct expression.

Hi,
I received a PM to respond to this one. So here goes my analysis.

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

Since the meaning of this sentence is very straight-forward, let me directly get to the error analysis of this question.

Error Analysis: The only error in this sentence is the SV number agreement error in the IC that begins after comma + FANBOYS. The subject of the IC after but is “what is much more difficult to determine”. This subject is a dependent clause. Whenever a clause or a phrase acts as a subject of a clause, it is always singular. So we have a singular subject here. But the verb for this subject is “are”, which is plural in number. Hence we have SV number agreement error here. This verb should be “is”.

PoE:
A. has been established by carbon dating, but what is much more difficult to determine are: Incorrect for the reason stated above.

B. have been established by carbon dating, but what is much more difficult to determine are: Incorrect.
1. Repeats the same SV number agreement error as in A.
2. Subject “The period” is singular and the verb used for it is plural “have been established”. We have another SV number agreement error here.

C. have been established by carbon dating, but that which is much more difficult to determine is: Incorrect.
1. Repeats the “have been established” SV error as in choice B.
2. Use of “that which” is incorrect as comma + FANBOYS should be followed by an IC.

D. has been established by carbon dating, but what is much more difficult to determine is: Correct. This choice rectifies the error of choice A.

E. are established by carbon dating, but that which is much more difficult to determine is: Incorrect. Incorrect
1. Plural verb “are” does not agree in number with singular subject “The period”.
2. Repeats the comma + FANBOYS error as in choice C.

Hope this helps.
Thanks.

The period - Singular - Has been established - Singular
what is - Singlular - much more difficult to determine - Should take singular - is

D is the right choice.

Dear Shraddha -As we are already on the topic of FANBOYS and ICs,

Machines powered by hydraulics are not driven by the steam produced by boiling water, but rather, high-pressure fluids are transmitted throughout the machine to various motors and hydraulic cylinders.

a) water, but rather
d) water; rather
e) water; but

1/Could you please let us know why D is wrong in the below sentence.

2 / Is the usage if "but" in A and B wrong?
Take for example - I not a mechanic but I can fix your car.
I not a mechanic, but rather a doctor.
So when I used comma but rather OR Comma but instead we need a noun right?

Cheers

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 period" is singular so E, C and D are out. "The reason" is singular so A and D are discarded. Auto click B without reading

(A) has been established by carbon-14 dating，but what is much more difficult to determine are
(B) has been established by carbon-14 dating，but what is much more difficult to determine is
(C) have been established by carbon-14 dating，but what is much more difficult to determine is
(D) have been established by carbon-14 dating，but what is much more difficult to determine are
(E) are established by carbon-14 dating，but that which is much more difficult to determine is

Experts,

I am confused on this one.

I am okay with ..

The period............has been.

But I am not okay with 'to determine is' construction.

What is much more difficult to determine is X,Y, and Z.

Inverted order: X,Y, and Z are difficult to determine.

So why use 'IS' instead of 'ARE'.

TGC!

If the fragment were "the things that are much more difficult to determine" then you needed an "are" (whether what follows "are" is "reason" or "reasons").

Because the subject (of this fragment) is "what is X" = singular, you need "is."

For e.g.
His contributions ARE doing X, doing Y, and doing Z.
His contribution IS doing X, doing Y, and doing Z.

Actually, I was confused too. But when I asked myself what is C-14 dating actually. Ans came up
Its like:
The era was established by (known by) this technology
Likewise;
The period has been established by a technique (i.e. C-14 dating)

C-14 dating is a technique.

Is the logic correct?
Pls guide

In the book that I am currently referring to, it says that when the "subject" of a sentence is a "noun clause", it is always "singular". In this case, the subject of the sentence is the clause: What is much more difficult to determine. Hence, it is singular and so, we use "is".

This question was first question in GMATPrep Mock1.

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．

(A) has been established by carbon-14 dating，but what is much more difficult to determine are
(B) has been established by carbon-14 dating，but what is much more difficult to determine is

Rest of the options are just junk.

mikemcgarry : Can you please help me here. I knew about substantive clause and even after knowing I got confused. I took the construction for the inverted sentence.
I normally get the inverted constructions wrong and I try to invert the sentence to determine the Subject - Verb agreement.

Any pointers for the same and some practice question as always.

Actually the book I am referring to says that when subject of a sentence is a "noun clause", it is always considered singular.

Here, the subject is "what is much more difficult to determine", which is a clause. So, it will be singular. So, verb "is" would be correct.

Another example (though not official) that the book gives is:

What statements politicians give is important.

My doubt is: when we have a list of actions, phrases or anything, what should we use?

Singular verb or Plural verb ?

IS the noun clause is always singular?

Thanks

[Reveal] Spoiler:
OA is B

Ans has to be B

1) The period........has [ here the subject is a noun ( the period ) and hence needs a singular verb ( has ).
2) what is much more difficult to determine..........is [ here the subject is a clause ( what is much more difficult to determine ) and whenever a phrase or clause act as a subject will always take a singular verb ( is ).

Moreover, here the verb ( is ) is not referring to the lists but to the clause. There is no doubt that if the the verb refers to a lists it must be plural verb, but here the verb [ is/are] is not referring to a lists rather referring to a clause that is acting as a subject.

Hope it cleared the doubt
