I marked D first.

But i think right answer is C.

Reason: we cannot tell about all french painters but yes only those that has painting in the Hoular Gallery.so Some French painters do not use acrylic monochromes in their works.

Pls correct me if I am wrong

I thought on these lines..

every painting by French
no painting by V
ie French not eq V
only V uses acm
ie F does not use acm
ie No F uses acm
Hence D.

If the information above is true, which of the following must also be true?
(A) No French painters are Vorticists. may be true, we only know abt french painter who worked at hoular gallery
(B) All Vorticists use acrylic monochromes in their works.again a may be true. we only know that only vorticists used acrylic monochorme, but we do not know if everyone of them used it.
(C) Some French painters do not use acrylic monochromes in their works.only vorticist used acrylic monochorme and they did nit have a painting in hoular. Hoular was painted by french painter. hence those french painter didn't used acrylic monochrome. correct answer
(D) No French painters use acrylic monochromes in their works. we do not if vorticist were frech painters or not. so this may or may not be true
(E) All French painters who use acrylics use acrylic monochromes in their works.again we do not know all french painter.

Could someone clarify whether we can say "Some French painters do not use acrylic" if in reality NON of the French painters use acrylic.
i.e. does "some do not use" means that in the same time "some DO use"
hope it's clear what I want to ask-)

This can be solved using Venn diagram.
Unfortunately your software does not support that.
Anyway I just try to describe it.
HG is a subset of French. Vorticists can be anywhere outside HG. Therefore, some Voticists or all Vorticists can be French. There is also another possibility of no Voticists are French. Acrylics is a subset of Vorticists.
Since V is outside HG and Acrylics are inside V, HG who are French are not Acrylics.

Your statement F does not use acm is wrong. That is only a possibility.

Some do not use does not imply some do use.
Think there are 4 persons A,B,C, and D.
You know that A and B do not use. However, you have no idea about C and D because nothing is said about C or D. Unless you verify them you cannot conclude that they use.

Can some one help me out in understanding why 'B' is wrong?

My understanding: Passage states " There are no paintings by Vorticist in the gallery. How the conclusion is arrived is becuase there were no painting made of acrylic monochromes. This implies that if there were painting made of Acrylic Monochoromes, then the painting was made by Vorticist"

Based on the observation listed above, it can be said that all Vorticist use Acrylic Monochromes since the paintings without Acrylic Mnonchoromes means there is no participation from Vorticist

Kindly some one help..

Since the question is a must be true- it seems option B is more appropriate but its quite direct and bold.
But how can we say option C - must be true as no link is provided between a French painter and acrylic monochromes.

As per the argument, we might also have a condition that none of the french painter use acrylic monochromes.

Please Suggest!!

Only Vorticists use acm means if there is an acm painting that is painted by a Vorticist. That implies all acms are painted by Vorticists. The converse is not true because there are some Vorticists who never painted acms. Yu got it!

B cannot be the answer as the argument only says that only Vorticists use acrylic. However, this does not mean all Vorticists must use acrylic.
In C - we need to assume that some French painters are Vorticists. For an inference question this option may not be correct.
Option D- As per passage without making any Out of scope assumptions I find this option correct !!

Yes, true. For both B and C . Thanks...!!
But again for D to be true, we also have to assume that none of the French painters are Vorticists.
