If all the statements above are true, which one of the following must also be true?


A) If there are no sophisticated listeners in the audience, then there will be no inspired musical performances in the concert.

B) No people who understand their musical roots will be in the audience if the audience will not be treated to a good show.

C) If there will be people in the audience who understand their musical roots, then at least one musical performance in the concert will be inspired.

D) The audience will be treated to a good show unless there are people in the audience who do not understand their musical roots.

E) If there are sophisticated listeners in the audience, then there will be inspired musical performances in the concert.

Let us write down the premises in simplified form -

IMP (Inspired Musical Performances) --> GS (Good show)

The second statement tells us that Good shows (GS) require Sophisticated Listeners (SL)
GS --> SL. (Note that this is the same as ~SL --> ~GS. look at the explanation for A to see how both the statements are same)

The third statement is this - SL --> UMR (Understand Musical Roots)

So, the three statements are this -
1. IMP --> GS
2. GS --> SL
3. SL --> UMR

These three premises can be combined to yield -
IMP --> GS --> SL --> UMR.
The correct answer will mention one of these links. Some of the inferences that can be made are IMP --> UMR; GS --> UMR; and IMP --> SL

A - let us write down what A means. ~SL --> ~IMP.
This can be rewritten as - IMP --> SL (Correct Answer)
(Let me illustrate this concept with a simple example -
If it rains, then there will be a traffic jam. This means that - Rains --> Traffic Jams.
This is the same as - WHENEVER Rains occur Traffic jams always happen. Consequently, if Traffic Jams do not occur, that means it did not rain.
that is ~Traffic Jams --> ~Rain).

B - can be rewritten as this - "if the audience will not be treated to a good show, then people who UMR will not be in audience"
~GS --> ~UMR OR UMR --> GS

Now, I know that GS --> UMR (Does not mean that UMR --> GS)
(Refer back to the 'traffic jam' example again. We know that Rain --> Traffic Jams. However, this statement need not be true - Traffic Jams --> Rains.
Traffic Jams can also be caused by various other reasons - strikes, peak hours etc. )

C - states this - UMR --> IMP. This reverses our inference - IMP --> UMR. Hence, incorrect (same reason as B).

D - 1st part = GS; 2nd part = ~UMR. The 1st and 2nd parts are connected by 'unless'.
Hence, I can write this as -
~GS --> ~UMR. this is the same as UMR --> GS (same reason as B).

(for options with unless - X does not happen unless Y happens. this means that for X to happen Y must necessarily happen.
So, we can write X --> Y. Note that we have negated the statement before the 'unless'. That gives us the sufficient condition).

E - this states SL --> IMP
this reverses the inference that we drew - IMP --> SL

Inspired Musical Performance (IMP) => Good Show (GS)
NO sophisticated Listner (SL)=> NO GS
Understand Musical Root (UMR)=> SL

A) - CORRECT
From statement 2, NO SL => NO GS and negating statement 1 NO GS => NO IMP.

Rest all other option is failing to have proper chain.

IMO A ; IMP -> GS; GS -> Slistn ; Slistn -> UnderM.Roots. Here only A says -> No Slistn => No GS which is contrapositive of 2nd statement.

There are three conditional relationships from the stimulus.

1. IMP --> GS
2. GS --> SL
3. SL --> UMR

You can use the transitive property and combine these statements to yield many different possible inferences

1 + 2 = IMP --> SL
2 + 3 = GS --> UMR
1 + 2 + 3 = IMP --> UMR

or you could have the contrapositive of any of these statements.

(A) ~SL --> ~IMP is the correct answer and is the contrapositive of the inference from the first two statements.
(B) ~GS --> ~UMR is the negation of the inference of the second and third statements.
(C) UMR --> IMP is the reversal of the inference of all three statements.
(D) ~GS --> ~UMR is the negation of the inference of the second and third statement.
(E) SL --> IMP is the reversal of the first statement.

For statements involving "unless"

_______ , unless ________.

What comes after unless is the necessary condition. Everything else gets negated and thrown into the sufficient condition.

I think A - D is very close but I am not convinced:I took 4 minutes on this, I don't think that's wise either.

If there are any inspired musical performances in the concert, the audience will be treated to a good show. But there will not be a good show unless there are sophisticated listeners in the audience, and to be a sophisticated listener one must understand one's musical roots.

If all the statements above are true, which one of the following must also be true?

A) If there are no sophisticated listeners in the audience, then there will be no inspired musical performances in the concert. - Possible - if the listeners do not feel its a 'good' show; there will be no inspired performances. Also the argument hinges on the concert quality and not listeners.

B) No people who understand their musical roots will be in the audience if the audience will not be treated to a good show.
No, we cannot comment on the thoughts of the sophisticated listener


D) The audience will be treated to a good show unless there are people in the audience who do not understand their musical roots.
- This is not what the argument says - it says 1) inspired performance = good show 2) good show = sophisticated listeners who have musical roots. But, that doesn't mean people who don't have musical sense make the performance less 'good' --> this is what D is saying: audience can have a good show only if people who have musical roots attend it. NO - it says good inspirational performance = good show and THEN the listeners. Also, I took a personal example - if I take my tone deaf friend (sorry :( ) with me to a complex sounding classical concert; she may not like it, but the performance could be inspired and there maybe other less tone deaf audience who attended a 'good show'

I felt there is a really subtle difference in the interpretation of D and A; and A is closer

Expert opinions?
