Here's my explanation:
: A person who is a concert pianist with a major orchestra is famous.Premise 2
: She is not famous.Conclusion
: She is not a concert pianist.
Let us solve this using Venn diagram. Consider a circle called 'Famous
'. Another circle called 'major orchestra' (MAJ_ORCH
). Let there be a third circle called 'minor orchestra' (MIN_ORCH
Now according to premise 1
, we can visualize the circle MAJ_ORCH completely inside
the circle called 'Famous
'. This is so because any
person who is a concert pianist with a major orchestra IS
famous. There is NO
concert pianist with a major orchestra who is not famous. Everyone is!
Premise 1 does not
say that 'A concert pianist who is NOT associated with a major orchestra cannot be famous
'. Even they can be famous
. We'll use this to show that option D
was something that the author did not consider to arrive at the conclusion.
Now if we consider option D, we can safely think of a circle MIN_ORCH
, which intersects
) another circle Famous
. This 'intersection' denotes that concert pianists who are working with 'minor orchestra' (MIN_ORCH) comprises 'Famous' & 'Not Famous' people
. Let Sarah be associated with 'minor orchestra' group
. Now since premise 2 states that Sarah is not famous
, she'll be a part of the circle MIN_ORCH, which is not common with the 'Famous' circle i.e., Sarah is a part of 'minor orchestra' and is NOT famous
(A) Sarah could be a famous actress. ---> Not relevant. We should not change Sarah's occupation. Let her be pianist for the time being
(B) Sarah could be a harpist for a major orchestra. ---> Not relevant. Why harpist? She is fine as a pianist
(C) Sarah could be a pianist with a rock group. ---> So what? Even if she's with a rock group, how does it, in any way, make the conclusion unsound?
(D) Sarah could be a concert pianist with a minor orchestra. ---> Explained above
(E) Sarah could be famous for another reason. ---> Sarah is 'not' famous for any other reason as Premise 2
clearly rules this out. So, we can discard this out.
My choice is option D
Hope that helps.
