A new advertisement is hanging in many of the East Coast subway stations. The poster proclaims: "Let the new biological pesticide containing micro-organisms be your new best friend! Because it's used by 4 out of every 5 florists, you can be sure that this product will answer your pesticide needs."

Which of the following, if true, most seriously undermines the advertisement's argument?

A) Though an efficient pesticide on the East Coast, the new biological pesticide has yet to undergo satisfactory experimentation in other areas.

B) The company promoting the new biological pesticide sent free samples of it to all florists in the urban centers of the East Coast.

C) Two years ago, most florists were using a chemical pesticide that was popular at the time while two years prior to that, another brand of chemical pesticide was considered the norm.

D) The Nursery Newsweek, published at the time of the advertisement, called on florists to move from chemical pesticides to biological ones, elaborating on the latter's advantages.

E) Pesticides are needed more in nurseries than in florist shops, where plants and flowers are usually held for short periods of time.

Still don't get why B is the correct answer. It talks about large sample size and this should strengthen the argument. I opted for E. Can anyone explain?

B is the correct answer because the fact that "it's used by 4 out of every 5 florists" is because it was given to them for free, and not because it is the best pesticide, making the argument that "this product will answer your pesticide needs." questionable.

I don't really see why E would weaken the argument.

Hi mascarfi,

I double the above claim. As per your statement, the samples were sent for free then all should be using it. But as per the claim made in the AD it is only a case of 4/5.

Normally the guy should either be a complete fake or a completely genuine one. The guy who put the ad is somewhere in between the two cases.

I will give my 2 cents for why I chose E.

As per the claim 4/5 florists use the pesticide. But as per E, nurseries require the pesticides and not florists hence any claim of 4/5 or even 5/5 will become useless since it is not required to be there at all in the first place thereby weakening the argument.

Would love to see your opinion.

Regards,
Dom.

Don't you think B is too vague.. B says samples sent "to urban centers of the East Coast" what if urban centers have less people and there other centers with more people (or say there are only 5 people in East cost, 1 in urban center and 4 in rural center) .Need some help please!

The question starts with “A new advertisement is hanging in many of the East Coast subway stations”, therefore I don’t think that "to urban centers of the East Coast" is vague at all, The company is clearly targeting customers in urban centers, since the advertisement is hanging on the subway stations.

I don’t think E weakens the argument. The fact that pesticides are “more needed in nursery homes” does not invalidates an argument saying "Let the new biological pesticide containing micro-organisms be your new best friend! Because it's used by 4 out of every 5 florists, you can be sure that this product will answer your pesticide needs.", it does not mean that they are not needed on florist shops as well.
They are using the “good statistic” of 80% of florists using their product in order to advertise it. Lets use another product to make the same comparison. Let’s say you have a laptop computer that is used by 4/5 of students, saying that it is more needed by engineers does not weakens an advertisement aimed to sell those notebooks for students.

The way I see it, “The company promoting the new biological pesticide sent free samples of it to all florists in the urban centers of the East Coast.” clearly weakens the argument by implying that the pesticide is only used because it was given to the florists for free, not because it was the best pesticide.

Hope it is clear now.

Thanks Mascarfi!

I'm confused that B is the correct answer because the answer itself is based on an assumption. The assumption is that florists will use whatever pesticide they get for free. There is no basis to assume that is correct. I was voting for A, but I understand that the argument doesn't care about other areas other than the East Coast. So I would probably go for B, using Process Of Elimination, but I'm not 100% sold on it.

I chose C, thinking it suggests that the mere use by florists isn't reliable indicator of pesticides' capability to meet the needs of florists.

There are lot of assumptions here. Even if the samples were given free, why would florists continue to use that brand unless the brand itself is good? If the florists used only the free sample, premise can't claim that they are using it (premise can't be challenged in weakening argument, conclusion needs to be challenged). If B needs to be right answer, then the premise in the advertisement needs to be an outright lie where a single plausible use of a product has been claimed as standard use of that product by 4 out of 5 florists.
