Thank you for using the timer!

There are many benefits to timing your practice, including:
Musical composers have generally made their most significant contributions to the musical canon before they reached the age of thirty. It is commonly believed that this is the case because aging brings about a loss of cognitive ability and creative capacity. However, a study pointed out that a disproportionately large number of those composers who made their most significant contributions to the canon after the age of thirty became musicians at an older age than is generally the case. Since by the age of thirty many composers have been engaged as musicians for a decade or more, these findings suggest that the real reason why musicians over thirty rarely make significant contributions to the musical canon is not that they have aged but rather that they have spent too much time as musicians.
In the argument above, the two portions in boldface play which of the following roles?
a.The first is an explanation that is challenged by the argument; the second is a finding used to support that explanation. b.The first is an explanation that the argument opposes; the second is an objection raised against the alternative explanation advocated by the argument. c. The first is a claim advanced in support of a position; the second is a finding that clarifies that position. d. The first is an explanation advocated by the argument; the second is a finding used to challenge that explanation. e. The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.
I Have not seen any books discussing bout how to approach these kind of C.R's .. If some one can share Resources it would be great. These C.r's hold lot of weightage.. score boosters.. Just dont neglect
I think having read just the first half part of this argument we can eliminate C and D, because it's clear that this explanation is challeged by the argument. B - the second is not an objection raised against the alternative, Out A - this finding does not support the exlanation, on the contrary, it present the alternative, Out. Only E is a logical description of the boldface portions of this argument.
Yeah! no Doubt these are tough Q's and the more accuracy one has in these type of Q's the better their score. I use POE most of the time for Bold faced CR.
(1) Contributions to M C A by MC after age 30 is less
(2) Aging -> drop in CA & CC
(3) large number of MC who made contributions after 30 became musicians late
(4) conclusion is Aging not the reason. Time spent becoming musician is the reason.
Now Before we look at answer choices, BF1 says some thing and C and hence the argument says the quite opposite.
So they are not in support of each other. Based on that we can eliminate C & D.
A B E all have the same about the first BF with a little bit of change (active/passive voice and different words)
A says the second is a finding used to support that explanation. referring back to the BF1. Clearly wrong. Its not offering any support to the explanation.
B says the second is an objection raised against the alternative explanation advocated by the argument.
I dont think the second is actually objecting the alternative agreement. In fact it supports it.
MC who make contributions after 30 are doing so because they became musicians at a later age. The argument says that MC's who do not contribute, do not contribute because they spend too much time and not because of age. So BF2 is saying that MC's who make contributions after 30 did not spend much time as M and hence the contributions.
E is left and says the second is a finding on which that challenge is based. . Sounds good to me for two reasons
(1) Its a result of a study and is a finding
(2) For the final conclusion to be true, it has to hold good.
powerscore CR book has some excellent exercises on such problems. although there are no bold-faced questions, there are plenty of insights, strategies and exercises on method of reasoning questions which, like bold-faced questions, require thorough understanding of the structure of the argument.
