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.

Last line says: No. of ppl (caffeine) = total no. of ppl (other addictive psych. sub)

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. [Correct. It is supported by the last line.]
(B) A physical addiction to a particular psychoactive substance will typically give rise to diverse psychological symptoms. [Only symptoms related with caffine are given. So, this is very broad generalisation. Incorrect]
(C) Not all substances to which people can become physically addicted are psychoactive. [Such refernce is not included in the passage. Narrow in scope. Incorrect]
(D) If one is physically addicted to a psychoactive substance, one will become unusually depressed when one is no longer ingesting that substance. [NO LONGER is special case. ppl will suffer if they are not given the regular dose rather than stop its consumption. Incorrect]
(E) If alcohol is a physically addictive psychoactive substance, there are not more people who consume alcohol than consume caffeine. [No menton of alcohol in the passage. Incorrect]

I got the answer wrong. Anybody who can help me out?

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 [addictive psychoactive substances]

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

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

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.

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?

...as many people consume caffeine as consume any one of the other [addictive psychoactive substances].

X = [addictive psychoactive substances]

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 [addictive psychoactive substance], 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.

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)?

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

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.


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

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!
