According to advertisements, the higher a suntan lotion’s sun protection factor, or SPF, the more protection from sunburn. In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter what SPF a suntan lotion has.
Which one of the following best identifies the error in reasoning made in the passage?
(A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn.
(B) Because some people get sunburned more easily than others, the fact that there are different SPFs cannot be ignored.
(C) It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion.
(D) It is unreasonable to assume that all suntan lotions require the same application.
(E) There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun.
Premise 1: Suntan lotion with Higher SPF ---> more protection from Sun.
Premise 2: For Suntan lotion to work, application before going in the sun & reapplication if needed.
Conclusion: It really does not matter what SPF a suntan lotion has.
The argument's conclusion is drawn from the fact that Suntan lotion needs to be applied before going in Sun & reapplication if needed, hence the SPF doesn't matter. A very weak reasoning to conclude into such a strong statement.
We need to find a flaw in reasoning.
Using POE,
(A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn. -
Simply attacks the premise, the conclusion is unaffected. Hence incorrect.(B) Because some people get sunburned more easily than others, the fact that there are different SPFs cannot be ignored. -
The argument does not say anything about a relation between SPF & Skin sensitivity. Hence incorrect.(C) It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion. - Hold.
(D) It is unreasonable to assume that all suntan lotions require the same application. -
Incorrect, we are concerned about SPF.(E) There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun. -
IrrelevantAnswer is C.
