Discontinuing the use of most habit-forming drugs causes emotional depression. While playing recreational sports can help reduce the emotional depression caused by discontinuing the use of such drugs, some amount of emotional depression is unlikely to be preventable.

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


A. Individuals who discontinue the use of any habit-forming drug will experience at least some emotional depression.
B. People who participate in recreational sports regularly are less likely to suffer from emotional depression than people who do not.
C. An individual who discontinues the use of an addictive opioid will most likely suffer from some emotional depression despite playing recreational tennis.
D. Individuals who use habit-forming drugs are likely to avoid emotional depression by continuing to use those drugs.
E. Playing recreational sports is the best way to reduce the amount of emotional depression caused by discontinuing the use of habit-forming drugs.

[prem] -hform drugs = depres
[con] while sports = -this depres, some depres isnt preventable;

(E) sports = -depres, but never stated it is the best form to -depre, out;
(D) continuing the use might avoid "further" depression, we don't know if its total depression or that avoided by the drugs, out;
(B) sports help -depres from discont drugs, doesnt say that those who do sports are less likely to get depressed, out;
(A) "most" drugs caused such effect, not all, out;

Answer (C).

I think this is a high-quality question and I agree with explanation. I would just add the assumption that an "addictive opioid" is a habit-forming drug

I think this is a poor-quality question and I don't agree with the explanation. C requires an assumption that an opioid is a "habit-forming drug". This is not stated anywhere, and would require prior knowledge and a big jump to the conclusion. I considered this option, but since opioid was not present anywhere in the initial statement, it felt like out of scope

Thank you for the feedback. 
The answer choice C says "addictive oppioid" - that means a habit-forming drug. I do not believe there is an issue with an assumption here because of the word "addictive"

While playing recreational sports can help reduce emotional depression, the passage does not compare those who play sports regularly with those who do not, thus is NOT necessarily true.­

The issue with choice C is really that the question asks for MUST BE TRUE. But Option C is at most MAY BE TRUE.

If someone is MOST LIKELY to suffer from depression after leaving drugs, then the statement itself contains a doubt and there is margin in the statement itself to allow for someone who might not suffer the depression.

Can you refer me to any OG question that tests this kind of concept where the question asks MUST BE TRUE but the correct option contains MAY BE TRUE statements ?

Hi. You can see a more detailed discussion and explanation here: 
https://gmatclub.com/forum/discontinuin ... 45225.html­

P.s. Where is this terminology from - "first family"? I am curious.

I don't think this question is very high-quality. You can easily make a case that addictive opioid is not within the group that cases emotional depression. Saw this question in one of the GMAT club mocks - ideally GMAT club should not include questions that have this level of ambiguity in them.

Sorry about the lack of logical cohesion between the context and the question. Are you suggesting we use another type of substance? I don't think the question writer knew enough about substance abuse. However, looking it up on Google, we found that opioids supposedly can cause depression https://www.webmd.com/depression/medici ... depression­

­I agree, I didnt see a comment that addressed how we can spot this error with C. When I was solving it I ended up elminating A,B,D,E for the right reasons but when it came down to C I was not sure since like you said we cant be sure if Opium falls into the "most" category so I ended up guessing and moving on since I felt I could not justify C anymore than the other choices.

Why is option A wrong?

Is it because the word 'WILL' implies ALL?
If thats the case, then option C also contains the word 'WILL', so its implying ALL isn't it?

Yes.
Remember, the passage says that MOST (not ALL) habit-forming drugs cause emotional depression. Thus, we cannot conclude that individuals who discontinue the use of ANY habit-forming drugs will experience at least some emotional depression.

So for option C, "will most likely" means most of the people only but not all?
Sorry for asking the basics, not a native speaker, many thanks!

Hi. No problem at all! 👍
All questions for learning are good and thank you for specifying the background - it helps address it better.

C. An individual who discontinues the use of an addictive opioid will most likely suffer from some emotional depression despite playing recreational tennis.


The short answer - YES.

The long answer. In this case, Option C is talking about an Individual, who is very likely to suffer. There is a very small difference between the two ways of saying almost the same thing so I think that could be translated as most people would suffer, it is just in a different format - it is cleaner than saying "Most individuals who discontinue the use of an addictive opioid will suffer from some emotional depression despite playing recreational tennis" there is that "likely" in there. Maybe someone smarter can see the differences between the two formats. I can see it but I don't think it changes anything whichever way you do it. or does it?
