Researchers have discovered that caffeine can be as

Question

Researchers have discovered that caffeine can be as physically addictive as other psychoactive substances. Some people find that they become unusually depressed, drowsy, or even irritable if they do not have their customary dose of caffeine. This is significant because as many people consume caffeine as consume any one of the other addictive psychoactive substances.

Which one of the following can be logically concluded from the information above?

(A) There is no psychoactive substance to which more people are physically addicted than are addicted to caffeine.
(B) A physical addiction to a particular psychoactive substance will typically give rise to diverse psychological symptoms.
(C) Not all substances to which people can become physically addicted are psychoactive.
(D) If one is physically addicted to a psychoactive substance, one will become unusually depressed when one is no longer ingesting that substance.
(E) If alcohol is a physically addictive psychoactive substance, there are not more people who consume alcohol than consume caffeine.

Guys, please, don't forget to provide brief explanation.

walker · Answer

Yeah, it's LSAT CR.

I think A is wrong because consumption and addiction is not equal.
I don't like "typically" and "diverse" in B.

So, E sounds good for me.

This is significant because as many people consume caffeine as consume  any one  of the other

E) If  alcohol is  a physically    , there are not more people who consume alcohol than consume caffeine.

In other words, we can always say that if X is   then X can't be consumed by larger number of people than caffeine.

ykaiim · Answer

In conclusion based questions, you cant bring outside info, which E states (Alcohol). If you check closely then A and E are same, just the new info in E. So, I think A should be the OA.

rockubabe · Answer

It's not A nor B. I also chose B.
The OA is E. I still don't know how...

Walker, how do we compare the amount of consumption of alcohol and caffeine from the given information?

walker · Answer

...as many people consume caffeine as consume any one of the other  .

X =

1. there is a set of all Xs
2. coffeine is one of X.
3. For any given X, the number of people who consume X can't be greater than those who consume caffeine.

Now, take a look at E.

(E) If alcohol is a physically  , there are not more people who consume alcohol than consume caffeine.

In other words, if something Y (alcohol or any other thing) belongs Xs, and we know that any X cannot be consumed greater than caffeine, then Y (alcohol) also can't be consumed greater than caffeine.

seekmba · Answer

I narrowed it to C and E...finally picked (E)

The argument says.....

the number of people who consume caffeine !> (not greater than) number of people who consume any one of the other addictive psychoactive substances.

E says...If alcohol is a (physically addictive psychoactive substance), there are not more people who consume alcohol than consume caffeine.

I would appreciate if someone can provide me a logical reason to discard (C)?

goforgmat · Answer

Between C and E ,i picked C. dunno on what grounds to reject C.

GMETER · Answer

The passage does not say anything about what psychoactive substances are so we can not infer whether physically addictive substances can or can not be psychoactive

(E) If alcohol is a physically addictive psychoactive substance, there are not more people who consume alcohol than consume caffeine.

Option E   is the correct answer as it represents a scenario related to the conclusion "  as many people consume caffeine as consume any one of the other addictive psychoactive substances.  ".

A  is extreme,  b  is wrong as just one symptom can occur,  c  is out of scope,  D  is wrong as depression is one of the three symptoms and it is not a Must symptom

C0achSteve · Answer

Option C is wrong because of the following line "Researchers have discovered that caffeine can be as physically addictive as  other  psychoactive substances." 
The author, by adding that "other" with psychoactive substances, has made caffeine a part of those substances too.

Hope it helped!
