In an interview that appeared in a weekly plumbing magazine, the chairperson of the Plumbing Association stated that plumbers are called 45% more on Fridays than on any other day of the week. The chairperson claimed that, though unexplained, it seems pipes are 45% more likely to burst on Fridays.

Which of the following, if true, would most seriously weaken the chairperson's claim that pipes are 45% more likely to burst on Fridays?

A) Not only plumbers but also electricians are requested to fix appliances on Fridays more than on any other day of the week.

B) People are more concerned about their houses being intact before the weekend than on any other time during the week.

C) A comprehensive survey of 504 households throughout the United States clearly shows that plumbers are called 45% less frequently on Sundays than on any other day of the week.

D) Plumbers charge twenty percent more for house calls made on Friday.

E) There is an undeniable correlation between the strength of the metal used for pipes and the anti-oxidizing coating it is painted with prior to installation.

B gives a good alternative for the 45% increment

why not A? is the answer to the question as it also weakens the argument above.................................

A is a good contender, however, B is the better choice.

If electricians get called in on Fridays as frequently as plumbers on Fridays, we might be inclined to think that there are things to fix on Fridays in general. The problem is that it isn't stated explicitly. Therefore it doesn't really weaken the plumber's argument of the increased likeliness to burst.

In contrast to that, B gives us a clear reason why people call plumbers more frequently on Fridays: They are more concerned about their houses on these days. This statement is a clear weakener and hence preferable over A.

Hope that makes sense to you :-)

In addition to that i want to give you a general pattern gmat follows. if something is happening/impacting in x then it does not mean same thing will happen/impact Y. always find the answer that is talking about X.
