Hi..

to answer this Q you have to understand WHAT exactly the following means

Quote:
makes it impossible for them to know for certain whether their actions are legal. Thus, under vague laws people cannot feel secure.


"Thus, under vague laws people cannot feel secure." MEANS that feeling secure is possible only when vague laws are not there..

Now contendos here would be A and C.

lets see the two choices

A. People can feel secure only if they know for certain whether their actions are legal.
this means EXACTLY as written above that - feeling secure is possible only when vague laws are not there..
correct

C. If people know for certain whether their actions are legal, they can feel secure.
this tells us the OPPOSITE - knowing for certain... is possible on;ly when a person feels secure.. eliminate

Hi mikemcgarry

I can not understand the difference between choice A and C .
Initially i thought the answer is D but later chose C as D out of context .
A and C look same to me in except how they are phrased .
I am confused between these two choices .
Please help me understand question such as this .

Thanks & Regards,
Arvind

Re: Vague laws set vague limits on people’s freedom [#permalink]
Why is D wrong. Please help me out.

If A happens B happens. But if A does not happened then B also didnt happnd.. So accordingly whats Wrong with D?

Hi yogesh610,

Here is the catch. What implication you drew was wrong.

If A happens, B happens

MEANS

B doesn't happen--> A doesn't happen. It is not the way you wrote.

Hence, D is incorrect.

Does that make sense?

Any place to learn such causal relationships? pretty confusing if it should be p->q or q->p

VL= Vague Law
K= Knowing
NK= Not knowing
S= Secure
NS= Not secure
(-->)= leads to


Now we have:

Premise VL--> NK
Conclusion VL-->NS


Now the assumption should be the logical link which is missing here.

Ask yourself under what condition VL-->NS given VL--> NK

You'll get this assumption:
NK-->NS => Now to feel secure I have to know (S can occur only when K occurs)
Remember K might lead to any of S or NS, we don't know. Hence, we can't conclude C.

If you are struggling with premise/conclusion relationships, I'd highly recommend you read my CR guide (in my signature) and invest in the Powerscore CR book. Both will highlight how to approach these relationships. Learning how these things interact with each other is paramount to doing well on the GMAT/LSAT.

Re: Vague laws set vague limits on peoples freedom [#permalink]
Vague laws set vague limits on people’s freedom, which makes it impossible for them to know for certain whether their actions are legal. Thus, under vague laws people cannot feel secure. The conclusion follows logically if which one of the following is assumed?

A. People can feel secure only if they know for certain whether their actions are legal. - CORRECT. POE helps.
B. If people do not know for certain whether their actions are legal, then they might not feel secure. - WRONG. Additional element of "might" that lets to change in meaning. Wish I had realised this prior to answer this one as correct.
C. If people know for certain whether their actions are legal, they can feel secure. - WRONG. Reverse relationship of
D. People can feel secure if they are governed by laws that are not vague. - WRONG. Out of scope as only vague laws what we are concerned with.
E. Only people who feel secure can know for certain whether their actions are legal. - WRONG. Like C only. If people are certain then they feel secure.

Vague Laws = A
Vague limits = B
Knowing certainty = C
Action are legal = D
People feel secure = E

A & B ----> nC(uncertainty) / D
Therefore,
A ----> E

What is then between C/D and E?
Though POE helps, but it is sure that we can say that only and only if people are certain, wherein nothing else matters, about their actions being legal, they feel secure.

Answer A.
