A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Profits from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz's economic interests.

Which of the following, if true, most seriously weakens the argument?

(A) Sales of canned tuna account for a relatively small percentage of Dietz Foods' profits.
(B) Most of the people who bought Dietz's canned tuna for the first time as a result of the campaign were already loyal customers of other Dietz products.
(C) A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year.
(D) Dietz made money on sales of canned tuna last year.
(E) In each of the past five years, there was a steep, industry-wide decline in sales of canned tuna.

That a profit was made on tuna last year is beside the point. After all, it may well be that profits would have been higher without the campaign.

E is correct because it indicates that sales of tuna last year would likely have been much less than 10 million units had it not been for the campaign

But the conclusion says the campaign did nothing to improve Dietz's economic interest. How does industry wide decline of Tuna sales weaken the line of argument?

D really says that the company made money .. it is no where indicated that the company is under loss in the past.

E says that there is industry-wide decine in sales but this campaign actually allowed the sales to increase - which says that the campain is successful and aided selling more tuna and thereby in the companys economic interest.

E

E clearly shows that because of Ad campaign the sales increased in times of industry wide decline in sales.

@Mohit and Dynamao

(C) A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year.

It tells up about the cause and effect;
expensive campaign --->more number of customers
less expensive campaign----> fewer number of customers

This may or may not be an obvious relationship.Better can be taken as an additional premise.
but we need an AC which can weaken the argument;(E) has it because it says that there was industry wise decline of tuna but somehow the campaign helped to acquire more customers though the profit was not very good.

Hope this helps !

Well C states that

A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year

Even if the less expensive campaign would have bought few customers one cannot comment whether those fewer customers would harm or do go good to the sales , its possible that fewer customers lets say 100 new customers that the less expensive one bought actually are responsible for the entire incremental sales then there is no harm to Dietz economic interest so C is discarded.

Does industry-wide mean every company company in the industry?
Because, if it does not then (E) is questionable. Since, Dietz Foods could have been an out-performer in the industry increasing sales Y-O-Y by more than 20%. But when the ad. campaign was launched it resulted in just 20% of increase in sales which is less than the more than 20% growth it was seeing earlier.

Thank you.

Thank you.

In critical reasoning questions, especially these kind of questions, there is generally no one correct answer. There is a best answer and there are less than best answers; we need to pick up the best one.

You are right that generally, industry wide phenomenon need not necessarily mean that each and every company is going through that. So, when we say that airline industry is facing severe losses due to intense competition among the players, we don't really mean that every airline company is facing losses; there could be some companies who would be making profits. What we mean is that the industry, as a whole, is in red (or in other words, if we combine the profit figures of all airlines, we would have a negative figure).

However, in this question, we have to assume that Dietz food was not an outlier in the industry because of two reasons:
1. There is nothing given to suggest this
2. If we assume this, this option loses its relevance and there are no other sensible options to weaken the argument at hand. So, to have a solution, we need to avoid such assumptions, which are based more on our real life experience than the understanding of the question.

My second reason may sound a bit strange but let's assume one of the options was:

Before last year, the company had gone through five years of continuous sales decline of its canned tuna.

Now, which one would you select? I would select this option now, since this is more specific and makes almost no assumptions about the performance of the company vis-a-vis industry, unlike option E. So, in this case, you can reject E saying that it makes such assumptions but not in the original question given.

Generally, the more an option relies on assumptions, weaker the option is (in both strengthen and weaken types of questions) and has lower chance of being the answer. However, if there is no other option even related to the argument at hand, then even this weaker option can be the answer.

PS: If you think C could have been the answer, then look again into it. It used unclear words two times within one sentence: "less expensive" - how much less - 10%, 20%, 90%?; "significantly fewer new customers" - how few - 60% less, 90%, 99%? The statement is too weak to be an answer.

Before we get to the logic of this question, lets understand the role a weakener should play:

A weakener decreases your belief in the conclusion. This means, that after reading the correct weakener choice and one should say that "I do not believe as strongly in the conclusion now" . Note, a weakener does not have to disprove the conclusion.

Lets now see the argument in the light of the above principle. We will first focus on the conclusion:

Conclusion: Clearly, therefore, the campaign did nothing to further Dietz's economic interests.

What does the conclusion mean: Considering that economic interests == profits, either short term or long term, the conclusion implies that the advertising campaign did not contribute to either.
Why does the author say this: The author makes this statement because the cost of the campaign is higher than the incremental sales (2 million cans), allegedly because of the campaign.

What could be some weakeners:
There could be two potential ways to weaken this argument:
1. If an answer choice projects the possibility that the campaign may have contributed for more than 2 million cans of sales.
2. If an answer choice projects the possibility that the new customers would become repeat customers; i.e. they would bring more sales in the future. Note this again means that the benefit from the campaign would be greater than the 2 million cans.

Choice E

1. Choice E projects the possibility that the campaign may have contributed for more than 2 million cans of sales. Hence is the correct choice.

Choice C

Choice C is actually completely irrelevant. lets look at choice C to understand why:
Quote:
A less expensive advertising campaign would have brought in significantly fewer new customers for Dietz's canned tuna than did the campaign Dietz Foods launched last year.

This is talking about a completely different campaign. It has nothing to do with whether the current campaign contributed to furthering Dietz's economic interests.

TakeAway: A weakener provides new information, which in the light of the information presented in the argument, reduces your belief in the conclusion. Secondly, a majority (95%+) of Weaken Questions have only one weakener.

why B is wrong?

B said the the first customers are become the loyal customer who buy in the future. This increase the belief that economic interest appear in the future. B is also a correct one.

Rajat, your above sentence is good. but I am not sure to understand you correctly. The following question from og 10 ilustrates the above sentence

- Manufacturers of mechanical pencils make most of the profit on pencil leads rather than on the pencils themselves. The Write Company, which cannot sell its leads as cheaply as other manufacturers can, plans to alter the design of its mechanical pencil so that it will accept only a new designed Write Company lead, which will be sold at the same price as the Write Company's current lead.

Which of the following, if true, most strongly supports the Write Company's projection that its plan will lead to an increase in its sales of pencil leads?

(A) First-time buyers of mechanical pencils tend to buy the least expensive mechanical pencils available.

(B) Annual sales of mechanical pencils are expected to triple over the next five years.

(C) A Write Company executive is studyiing ways to reduce the cost of manufacturing pencil leads.

(D) A rival manufacturer recently announced similar plans to introduce a mechanical pencil that would accept only the leads produced by that manufacturer.

(E) In extensive test marketing, mechanical-pencil users found the new Write Company pencil markedly superior to other mechanical pencils they had used.

in this problem B is considered "not in the light of the information presented in the argument" and is wrong. E is considered "in the light of information presented in the argument" and is correct.

is that what you mean, Rajat?, pls confirm this point.

can I say that the weakener/strengthener is information which increases doubt/belief that the evidence will make the conclusion, not the information which increase doubt/belief that the conclusion will happen independently from the evidence.

is my thinking correct here? pls confirm.

Why not answer can be (B). as it states that "MOST" people who bought for the first time as a result of "CAM" and they were already loyal to other products and will be loyal to this one also(Well that is not an assumption !!!!!)

Although (E) can also be the answer as it => that sales are far more than 2 million => that proportionate increase in old profits which matched = "CAM" costs

I am still confused about this question. By "economic interests" I would assume it means money. I understand that the campaign lead to 2 million or more cans of tuna being sold. But, if the profits of the additional cans were substantially less than the cost of the advertising campaign, how can it be said that the campaign furthered Dietz's economic interests. Please explain.

Please explain.

lets take 5 years as 1 2 3 4 5
year 1 =30 tuna sold
year 2 =25 tuna sold
year 3 =20 tuna sold
year 4 =15 tuna sold
year 5 =10 tuna sold
year 6 =12 tuna sold
since tuna selling was on a steep(was decreasing ) so increase in 2 tuna dont you think furthered economically.
hope it helps

let me know if you have doubt.
