Hi everyone!
I searched for this question on the forums and had not found a topic, even though its marked as a difficult question (171 level). After review the AC is fairly obvious, but I am posting to help people that may be confused by this question, and if I say anything wrong, please correct me!
This question is a Necessary Assumption question, basically meaning that if the answer choice is not true, the argument totally falls apart.
A: Incorrect, this does not have to be true for the argument to stay together.
C Incorrect: Who cares about other arts?
D : Incorrect: It does not need to have increased for the argument to be ok, more shows with the same amount of people also works as an increase in public interest.
E: Incorrect: My AC during the test. This is incorrect because it does not matter what the intentions of the opera companies were when they established their companies. All the argument talks about is an explosion of public interest for opera, and that 45 companies founded in the last 30 years, is evidence for this. Assuming E is false, it does not destroy the argument.
Therefore the correct answer is B Which must 100% be true. If its not true, that at a minimum, 45 opera companies opened and ceased operations in the time period where the argument is saying public interest EXPLODED. Do you see the problem here? If all 45 of those founded companies went out of business in the same time period, can you really claim this to be the reason opera exploded in public interest?
After hearing J.Y. explain this question, it makes perfect sense to me why the answer is E and not C. I am just going to write down a little bit of my thought process here, it might help somebody.
For an MSS question, out of the 5 ACs, your are looking for the 1 that can be supported by the statements above. For this type of question what is really helping me, is making sure the ACs can relate to what we actually know from the stimulus.
Using this above you can eliminate A, B, D
A: We only know it can improve typing speed, not that most people are improved by using this configuration - too strong of a statement.
B: Stimulus does not mention new typewriters and how they are worse than old ones - this is like really irrelevant
D: Stimulus somewhat mentions this, but the opposite and how we will never switch due to the cost and inconvenience. Also, we really do not care if it would benefit society as a whole, benefits like that are never mentioned in the stimulus.
Moving on to the two polarizing answer choices C and E, we will start with the wrong answer choice.
C: Although harder to visualize, (This is the answer I picked during the test AND BR) it does not matter to the early typewriters what kind of innovations would happen in the future. They invented this typewriter, which helps copy things down in a timely and less costly manner, so because there is going to be this innovation in the future, they should make a more inconvenient typing layout so people can type faster in the future? Reading that you should realize how little sense that makes.
E: This is subtly correct, but it is really the only AC with support from the stimulus. We know from the stimulus that typewriters made that layout so people would not be able to type as fast due to jamming. Now in the present, we know that keys do not jam frequently, or at least can be designed that way, for computer keyboards. Therefore, in this hyopthetical situation, where if the keyboard was invented for something that did not jam, of course they would not have to use the clunky, awkward set up of keys.
