Can anyone please explain to me why option E is incorrect?

broall · Answer

A. Most oil paints require about 24 hours for drying.
 This choice indicates that 24 hours for drying is an appropriate time, so new product Miloseal which could protect the painting up to 48 hours is unnecessary. This choice could be good. However, the problem with this choice is the word "most". This means that there are some oil paints that require more than 24 hours for drying. Hence, using new product Miloseal could still be beneficial

B. Most varnishes are produced by companies that do not produce oil paint.
 This choice is irrelevant to the argument.

C. The protection given to oil paintings by Limolex is more than sufficient to keep them safe for 24 hours.
 Correct. Unlike choice A, this choice indicates that all oil paints require less then 24 hours for drying.
 Thus, it is no need to use new product Miloseal that provides the longer protection duration.

D. Miloseal does not provide protection for water colors while Limolex could work with certain kinds of water colors.
 Proctection for water colors is irrelevant. The argument focuses on protection from dust and other foreign particles

E. The protection that Miloseal affords to paintings that use both oil and acrylic paints is only half as good as that provided by Limolex to such paints.
 "oil and acrylic paints" is irrelevant. We care about oil paints only.
"as good as" is irrelevant to the arugment, which focuses about the protection duration.

Which of the following statements, if true, would most seriously call into question the claim made by Miloseal's marketing agent?

A. Most oil paints require about 24 hours for drying. - This is a fact stated in the premise. No new information is given by this option. Incorrect. 
B. Most varnishes are produced by companies that do not produce oil paint. - Okay. So what? Irrelevant. 
C. The protection given to oil paintings by Limolex is more than sufficient to keep them safe for 24 hours. - Correct. Even if Miloseal protects the oil painting for 48 hours, the extra number of hours for which the protection is given are not really required. Limolex is more than sufficient for protection of the oil paintings because the paintings require only 24 hours to dry (as per the premise). Thus, Miloseal isn't giving any competitive advantage to the users. 
D. Miloseal does not provide protection for water colors while Limolex could work with certain kinds of water colors. - We are worried about the oil paints. 
E. The protection that Miloseal affords to paintings that use both oil and acrylic paints is only half as good as that provided by Limolex to such paints. - acrylic paints are out of scope.
