A specific skin rash has been linked to exposure to certain types of high-intensity tanning beds. While not dangerous, these rashes are painful and often unsightly, at least in the eyes of those who contract them. Over 90% of females ages 24-30 who use a particular tanning bed called "The Bronzer" have contracted the rash in varying levels of severity. Although using "The Bronzer" does not always lead to a contraction of the rash, the only way to completely avoid the rash is to refrain from using "The Bronzer" and other tanning beds altogether.

Which of the following indicates a flaw in the author’s reasoning?

A. It relies on evidence about a specific product to make a recommendation about an entire class of products.

B. It assumes that one possible cause of a condition is the only cause of that condition.

C. It assumes to be true what it sets out to prove.

D. It makes a generalization based on one segment of the population.

E. It contradicts itself by proclaiming a condition to be not dangerous and then offering a recommendation to avoid that condition.


Thanks and regards,
Sidd

I think that option A and d are both correct and hence either cannot be considered as the correct answer.Now option B,C and E are left. Option E can be eliminated since its out of scope. The argument is concerned about the banning of the product as a whole....
Out of B and C Option B is right since the argument recommends on the basis of just one reason mentioned.....and does not considers other reasons to eliminate the options..

Hence Answer is b

Please explain as i am totally stumped by this one.

Hi Sidd,

It is an LSAT question and LSAT questions have a list of error types and this one comes under the category of "False Causation"

The stimulus says that Bronzer is the cause of rash in females who use this tanning bed. Then goes on to conclude that the ONLY way to avoid the rash is to be away from any kind of tanning bed.

Well, if you notice, this is a very far fetched conclusion. It is similar to saying "90 % of people catch cold if they get wet in the rain, so the only way to stay away from cold is to not to get wet in any possible way". The author does assume one cause of a problem as the only cause; this in fact is the flaw in the reasoning of the argument. Most other answer choices are telling what the author is doing to make a conclusion but not identifying the flaw in reasoning.

Hope that helps,

Vercules

Hi Sidd,

D. It makes a generalization based on one segment of the population.

Yes the author is making generalization based on one segment of population, but it still does not explain the flaw. It is something that the author is doing.

Suppose we correct this point and change in the stimulus so that it includes the segment of population discussed: "the only way in which females aged 24-30 can avoid rashes is to stay away from Bronzer and other tanning beds". Would this make the argument no longer flawed? No; therefore (D) is incorrect.

Hope that helps,

Vercules

Hi Archit,

Now lets consider answer choice A

(A) It relies on evidence about a specific product to make a recommendation about an entire class of products.

Similar to (D) the author is doing this; i.e. the argument does relies on evidence about Bronzer to make recommendations about an entire class of products. If we address the point mentioned in (A), the argument still remains flawed.

lets change the argument so that (A) is addressed.

New Conclusion: The only way to stay away from rashes is to refrain from using "Bronzer" tanning bed.

In this case we are not making a recommendation about an entire class of products. But, the argument still remains flawed in its reasoning because even after refraining from just "Bronzer" tanning bed does not guarantee that one will not catch the rash. So, the reason mentioned in (A) in not the flaw in reasoning.

Hope that helps,

Vercules
