In North America there has been an explosion of public interest in, and enjoyment of, opera over the last three decades. The evidence of this explosion is that of the 70 or so professional opera companies currently active in North America, 45 were founded over the course of the last 30 years.

The reasoning above assumes which one of the following?

(A) All of the 70 professional opera companies are commercially viable options.
(B) There were fewer than 45 professional opera companies that had been active 30 years ago and that ceased operations during the last 30 years.
(C) There has not been a corresponding increase in the number of professional companies devoted to other performing arts.
(D) The size of the average audience at performances by professional opera companies has increased over the past three decades.
(E) The 45 most recently founded opera companies were all established as a result of enthusiasm on the part of a potential audience.

IMO B

(A) All of the 70 professional opera companies are commercially viable options.
The argument doesn't mention the "commericial" aspect, this adds informations and the conclusion cannot be based on added information in the answer.
(B) There were fewer than 45 professional opera companies that had been active 30 years ago and that ceased operations during the last 30 years.
Correct (IMO)
(C) There has not been a corresponding increase in the number of professional companies devoted to other performing arts.
This is a good one... but since the passage doesn't mention any other art, I discard this and pick B.
(D) The size of the average audience at performances by professional opera companies has increased over the past three decades.
This option mention the "average", not the "number". Moreover the text links the increase of the number of bands to the explosion of public interest, and does not say anything about the audience.
(E) The 45 most recently founded opera companies were all established as a result of enthusiasm on the part of a potential audience.
The word "all" makes this answer too extreme

Do not take for granted all the times that the words "too extreme" are always wrong, though

'E' for me. Whats the OA.

As mentioned, 45 founded companies in last 30 years forms the basis for the conclusion of argument. Therefore, author must have assumed that 45 companies founded are the result of increased public enthu.

i think the answer must be B.
E is close but it just strengthens the fact that "Public likes the operas established in the last three decades or Operas are bound to make good profit or Opera is making a good business" But we are asked to find an assumption or support for the fact that it is against the public interest on the basis of an evidence that 45 out of 75 operas are founded in the last 3 decades." So the gap is "How can there be explosion of public interest if more number of operas are opened in that particular decade."
If we weaken the fact that all these operas in discussion are opened in the last three decades and not carried fwd frm previously running operas.
Than we can protect our conclusion.

Consider Kudos If my post helps!!

be flexible. Do not rely always on the negation technique: though is the most powerful tool for assumption questions, try to understand the question itself, too

this is what is our conclusion and what lead to it

The evidence of this explosion is that of the 70 or so professional opera companies currently active in North America, 45 were founded over the course of the last 30 years.

(E) The 45 most recently founded opera companies were all established as a result of enthusiasm on the part of a potential audience.

As you can see is completely unrelated to our conclusion.

Basically it says that NOW still exist more than 45 companies founded over the course of the last 30 years.

In E we see that something is RECENTLY founded due to the ENTHUSIASM of POTENTIAL audience. This is completely incosistent with our argument.

Hope is clear

Conclusion > People like opera nowadays because 45 schools opened in the last 30 years.

A - No one cares
C - Again no one cares
D - The size of the average audience could have gone from 1 to 20000000000000, but yet again no one cares because the average size of the audience
is not the criteria used to advance the conclusion. The criteria is based on the # of opera companies not the amount of monacle wearing gentleman who attend operas.
E - This means zilch because the companies have already been founded, so wether or not the companies were founded because I was enthused doesn't matter at this point. Again, enthusiasm does nothing to advance the conclusion because it only talks about a "part" of a potential audience. That potential audience could be 1 billion people or you and your dog.

B
Negated > There were more than 45 professional opera companies that had been active 30 years ago and that ceased operations during the last 30 years.

Imagine If there were 1 billion opera companies, and now there are 70 opera companies.
Now imagine that only 45 opened during the 30 years that 1 Billion opera companies closed. (+45) + (-1Billion) = wrecks this argument

In North America there has been an explosion of public interest in, and enjoyment of, opera over the last three decades. The evidence of this explosion is that of the 70 or so professional opera companies currently active in North America, 45 were founded over the course of the last 30 years.

currently 70 => 45 founded this year => so interest will be high.
1> what if earlier opera were 200 and now it's only 70 so closed opera are two many, in that case definitively interest has decline.
2> Even though 45 new has opened, they have kept their capacity very low. 30 that opened that were opened earlier holds huge audience capacity. 45 new has opened because their are some areas where there are no opera. It was location specific decision and not driven by sudden audience interest.

No. of people who watch opera = avg audience size * total no. of opera

The reasoning above assumes which one of the following?

(B) There were fewer than 45 professional opera companies that had been active 30 years ago and that ceased operations during the last 30 years. Correct

(D) The size of the average audience at performances by professional opera companies has increased over the past three decades.
The size of the average audience at performances by professional opera companies has not increased over the past three decades.

even if avg audience size has not increased, if operas has increased, good enough sign that public is interest.

(E) The 45 most recently founded opera companies were all established as a result of enthusiasm on the part of a potential audience. Negate - The 45 most recently founded opera companies were not all established as a result of enthusiasm on the part of a potential audience. so what?? even if 44 are opened as a result of enthusiasm on the part of a potential audience., conclusion stands corrected.
