Q19 - Anyone who believes in democracy

[AllyMaeBell]

19. B
Question Type: Assumption

This question asks us to find a sufficient assumption, meaning one that, if true, will be enough to make the argument true. To tackle this question, we first find the core:
Premise #1: Anyone who believes in democracy has a high regard for the wisdom of the masses.
Premise #2: Griley believes that any artwork that is popular is unlikely to be good.
Conclusion: Griley does not believe in democracy.

Second, we find the assumption. Where is the mismatch between the premises and the conclusion? The only thing we know about Griley is that he thinks that any popular artwork is unlikely to be good. The only think we know about believing in democracy is that anyone who does so also has a high regard for the wisdom of the masses. Since the conclusion links Griley to not believing in democracy, it must be assuming that since he thinks popular artwork is unlikely to be good, he does not have a high regard for the wisdom of the masses, and therefore can’t possibly be someone who believes in democracy. Let’s look at the answer choices.

(A) This does not connect us back to our conclusion"”it has no mention of believing in democracy. It also does not link our premises together.
(B) Bingo! This links the premises together, which allows us to draw the conclusion. This is correct.
(C) We know that Griley is an elitist, so this is not helpful.
(D) This is the reverse of what we need.
(E) This doesn’t incorporate what we know about Griley, so it can’t help us link to the conclusion.

Conditional logic once again.

BD -> HRW
Gr -> E -> P -> Good~
[Gr -> ~BD]

Gr -> (E->P-> Good~) / ~HRW -> BD~

A) P-> GOOD~ -> E
B) P-> GOOD~ -> ~HRW
C) GR -> E~ -> HRW~
D) HRW~ -> E -> P -> ~GOOD
E) G -> BD -> ~ HRW

If this is right (which it may not be), then why is D wrong?

Thanks

Gr -> (E->P-> Good~) / ~HRW -> BD~

A) P-> GOOD~ -> E
B) P-> GOOD~ -> ~HRW

D) HRW~ -> E -> P -> ~GOOD
E) G -> BD -> ~ HRW

If this is right (which it may not be), then why is D wrong?

Thanks

D: believe in democracy

HR: High regard for wisdom of Masses

GR: Griley

P = ~G: Any artwork that is popular is unlikely to be good.

P1: D --> HR

P2: GR --> P = ~ G

--------
C: GR --> ~ D

We wan't something that connects ~HR --> ~D wit P = ~G.

(B) Does that.

It gives us the following chain.

GR --> P = ~G --> ~HR ---> ~D

(D) suggests that ~HR ---> P = ~G

It is the reverse of what we want.

This is how I diagrammed mine:
P-Popular
WM-Wisdom of the masses
G/~G- G for Griley and 'Good'.

So it goes;
P-WM-G/~G and
G/G-~WM/~P.

So B is the answer since it is consistent, hence, B.

So I see why D is wrong and why B is correct but what threw me off was the "elitist" part in D. For some reason I thought "elitist" was a separate condition part of the logic chain to look like:

Believe in democ --> high regard for wisdom of masses
G is an elitist--> ~~believe any popular artwork is good --> ~~believe in democracy

Was this chain wrong to include the G is an elitist? Or is this just part of the "--believe any popular..."?

The conclusion is "Griley doesn't believe in democracy".

So you need two ingredients:
1. If you're XYZ, you don't believe in democracy.
2. Griley is XYZ

Do we have either of those?

1. If you don't have high regard for the wisdom of the masses, you don't believe in democracy.

2. Griley is an elitist
2. Griely believes that popular artworks are unlikely to be good

We were given the criterion for concluding "you don't believe in democracy", but we were never told that Griley meets that criterion.

So what we're missing is a way to get from what we know about Griley to the criterion we need for "you don't believe in democracy".

There are two possible answers:
"If you're an elitist, then you don't have a high regard for the wisdom of the masses"
or
"If you think popular art is unlikely to be good, no high regard for wisdom of masses"

Both of those are equally useful, in terms of our logical task. And both of them make sense conversationally. We can imagine how one would assume that elitists don't respect the masses, and we can imagine how one would assume that someone who looks down on popular art doesn't respect the masses.

(D) is just wrong because it's backwards.

If it said
"Anyone who is an elitist who believes that if an artwork is popular it is unlikely to be good does not have a high regard for the masses"
then it would be correct

I got this question right . However, D was very tempting to me. When I went through the explanations I see why my choice B is right but not why D is wrong. I must say, I have a hard time doing conditional in LR under time and that's why most of the time I focus on the stimulus wording rather than trying to diagram.

Thank you
