People who browse the web for medical information often cannot discriminate between scientifically valid information and quackery. Much of the quackery is particularly appealing to readers with no medical background because it is usually written more clearly than scientific papers. Thus, people who rely on the web when attempting to diagnose their medical conditions are likely to do themselves more harm than good.

Which one of the following is an assumption the argument requires?

(A) People who browse the web for medical information typically do so in an attempt to diagnose their medical conditions.

(B) People who attempt to diagnose their medical conditions are likely to do themselves more harm than good unless they rely exclusively on scientifically valid information.

(C) People who have sufficient medical knowledge to discriminate between scientifically valid information and quackery will do themselves no harm if they rely on the web when attempting to diagnose their medical conditions.

(D) Many people who browse the web assume that information is not scientifically valid unless it is clearly written.

(E) People attempting to diagnose their medical conditions will do themselves more harm than good only if they rely on quackery instead of scientifically valid information.

Answer: E

Let's decode the stimuli first:
difficult to distinguish between scientifically valid information and quackery.
quackery appears appealing -> will do more harm.

Now, lets check the options

(A) People who browse the web for medical information typically do so in an attempt to diagnose their medical conditions.
-already given

(B) People who attempt to diagnose their medical conditions are likely to do themselves more harm than good unless they rely exclusively on scientifically valid information.
- correct ( try to negate this option )

(C) People who have sufficient medical knowledge to discriminate between scientifically valid information and quackery will do themselves no harm if they rely on the web when attempting to diagnose their medical conditions.
- we are not concerned with People who have sufficient medical knowledge rather with people who rely on the web

(D) Many people who browse the web assume that information is not scientifically valid unless it is clearly written.
- this option does not tell us anything

(E) People attempting to diagnose their medical conditions will do themselves more harm than good only if they rely on quackery instead of scientifically valid information.
- wrong option. People attempting to diagnose (but we don't know if they are diagnosing on we or not)

QUESTION TYPE: Necessary Assumption

CONCLUSION: People who rely on the web to diagnose their medical conditions are likely to do themselves more harm than good.

REASONING: People who look for medical info on the web often can’t tell what is scientific and what is quackery (nonsense). A lot of the quackery is attractive because it is more clearly written than scientific papers.

ANALYSIS: The argument is assuming that people will often hurt themselves if they rely on quackery. But this doesn’t have to be the case. Maybe quackery is harmless or occasionally beneficial.

___________

A. This isn’t necessary. It’s only necessary that when they do try to diagnose themselves, they hurt themselves more often than not.
Negation: Most of the time, people browsing the web for medical information aren’t trying to diagnose themselves.

B. CORRECT. If people are not more likely to do themselves more harm than good even if they look at quackery then this argument isn’t much good.

C. This isn’t necessary. The argument would actually be slightly strengthened if some of these people hurt themselves too.

D. This would be helpful to the argument, because it would mean that people might assume that quackery is scientific. But it doesn’t need to be true.
Negation: Few people who browse the web assume information is not scientifically valid unless it is clearly written.

E. This isn’t necessary. The argument is fine if some people manage to harm themselves despite looking only at scientific literature.
Negation: People attempting to diagnose themselves may hurt themselves even if they only use scientific literature.

boil down to B and D, now I can clearly see B is the answer.
Fortunately, this is not gmat-style question b/c negate D is quite trouble-some, test takers can skip this question.

let me try to explain if still you have not got the answer-

For Assumption Question it is always advisable to go through negation method
so basicall we have to find the option if negated breaks the Conclusion

Premise - Much of the quackery is particularly appealing to readers with no medical background because it is usually written more clearly than scientific papers

So basically Conclusion is followed by tHus, because here author thinks that Secientfic papers are good but Quackery is bad, so assumptyion should be that If you are taking teh help of Scientific paper it will not cause harm

Conclusion of this argument is -

Thus, people who rely on the web when attempting to diagnose their medical conditions are likely to do themselves more harm than good.

No we will go to Option -

A. People who browse the web for medical information typically do so in an attempt to diagnose their medical conditions.

After Negation - People who browse the web for medical information typically do not do so in an attempt to diagnose their medical conditions.

This negation is not Breaking down the Conclusion but you are just createing your own negative conclusion because Conclusin is telling that there are soem people who rely on web to diognize medical condition

B. People who attempt to diagnose their medical conditions are likely to do themselves more harm than good unless they rely exclusively on scientifically valid information.

After Negation - People who attempt to diagnose their medical conditions are likely to do themselves less harm unless they rely exclusively on Quavkery information (Opposite of Scientific)
Rest all other option can be discared.
