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 them 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 the flaw in author's reasoniong?

a. it relies on evidence about a specific product to make recommendation about an entire class of products
b. it assumes that one possible clause 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 generaliztion based on one segment of the population
e. it contradicts itself by proclaiming a condition to be not dangerous and then offering a recommandation to avoid the condition.

I think it is B. What is the OA?

My reasoning is based on the fact that the segment uses the word only to say that only staying away from tanning beds is the only way to not contract the rash

Both B and D seem equally right to me as both point the to the narrowness in the argument.

Can you post the source please..

" 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. "

Here, Bronzer is always not the cause of Rash -- > It means something else can also be the cause for Rashes....

So, by completely avoiding the Bronzer or tanning bed may not help in not getting Rash...

Hence - D

Whats OA ?

This is a tough one...I thought A/B/D are equally close but went ahead with D...thinking that author is making a statement for entire population based on data about a particular population group...

Would like to see the source and some expert's take on this one....
