A rare type of bacterial has killed off many tuna fish in North America; fishing boats have had very meager catch of tuna this year. As a result the whole sale price of tuna meat has increased significantly. Therefore the retail price of tuna based cat food is certain to increase within six months.

The answer to which of the following questions would provide information relevant to evaluating the claims made in the argument above?

A.Can the bacteria be eliminated within the next six months?
B.Are consumers willing to spend more for tuna based cat food?
C.Has the price of cat food remained steady during other period of poor tuna catches?
D.What percentage of tuna in North America were affected by the bacteria?
E.Have the prices of other ingredients in tuna based cat food decreased recently?

IMO: E

Rest of the options do not seem to be having any effect on the main issue at hand.

Why is C not the answer? If the prices remain the same during other periods of Poor Tuna catches it would mean that tuna meat is probably a small ingredient or the price of Tune is not very high to have an effect.

Whereas with Option even f the prices of other ingredients decreased, is the decrease high enough to offset the increase of prices of the Tuna fish

The conclusion of the argument is about increase in retail price of tuna based cat foot in coming future. The argument is trying to make two leaps of connections they are whole sale price Vs retail price and increase today Vs increase within six months.

Having looked at the options, there was a confusion between C and E. C talks about past time period which I believe could be irrelevant to current argument. Because there could be many other factors which will impact retail price such as demand etc., Past may not be an accurate representation of current time. Also, C doesn't make any case for future estimated price. E on the other hand mentions about other ingredients which seems logical. Because since the cat food dealers don't want to loose business, they might have made sure that other ingredients price stays low hence the overall price of cat food stays constant. Hence E is right answer.

Why not A , we want to evaluate the argument so that two extreme cases gives the right answer,in E option it is taking about recently and argument is talking about within next six months so how come the answer is E. There might be chances that within six months ingrediants may fluctuate...
Whearas a is taking about within six month period
If in within six months bactarias are eliminayed there price will no go high..
If bacterias will not elimante thn argument will be rght by its own....

I also think that the answer should be C. I'm not able to get why the price of there ingredients affect the prices of Tuna fish.

The cat food is Tuna Fish based Meaning one of the ingredient in the cat food is Tuna fish.

Now decrease in the price of other ingredients could actually nullify the effect of increase in the price of Tuna fish but we don’t know how much is the increase or decrease

If consumers are not willing to spend for the tuna best cat food, then the demand will not be high. This, in turn, would mean that the prices will not rise. Based on this thinking, why is B not the answer?

The question asks about an option who's answer provides some information relevant to evaluating the claim. The claim was that the prices of the cat food will increase. That will itself depend on the prices of the raw materials (tuna and other things). The manufacturing price will increase unless the prices of other ingredients in tuna based cat food decrease. So that's why, I think that E is the correct answer we are looking for.

Also, B gives us the answer from customers point of view. Even if the customers are not willing to spend more, they will be buying the minimum amount of cat food which should not affect the manufacturing prices of the product.

Hmm, still not getting it as clearly. The price of tuna has risen due to unavailability. Customers can still buy non-tuna based cat food and refuse to buy tuna-based catfood which will drive the prices down due to low demand.

Conclusion: the retail price of tuna based cat food is certain to increase within six months.

The answer to which of the following questions would provide information relevant to evaluating the claims made in the argument above? ---- evaluate above given information.

A.Can the bacteria be eliminated within the next six months? --- Lets consider the answer yes. in that case the price for cat food will not increase. if answer is No. i understand the answer is no. but more important question in this case will the problem remain the same. In gmat its a very basic rule never kill a problem. just weaken it. in this case problem will not remain as it is maintained above.
B.Are consumers willing to spend more for tuna based cat food? --- yes or no either way it is not affecting this problem.
C.Has the price of cat food remained steady during other period of poor tuna catches? --- what happened in those situation has nothing to do with this one.
D.What percentage of tuna in North America were affected by the bacteria? ---- again an irrelevant factor.
E.Have the prices of other ingredients in tuna based cat food decreased recently? --- let say yes. while tuna price increased. over all process will not increase. while if prices of other ingredients not decreased or increased then overall prices will increase. E is the correct ans.

We know that tuna meat price is increased but tuna based cat food price

If it's other ingredients price is decreased then we are not sure whether price would increase or not
But if price of other ingredients remains same then its price can go up
E goes in both ways so it sbest option

B doesn't correlate with situation ,in argument we know nothing about consumer behaviour so it is wrong

All other options are not addressing concern of price for tuna based cat food

aragonn Why D is irrelevant?

If high percentage of tuna is affected then yes price will increase , if less percentage or negligible percentage of tuna is affected then price will not increase

prags1989 - Let see what is relevant here.

As a result the whole sale price of tuna meat has increased significantly >>>> Therefore the retail price of tuna based cat food is certain to increase within six months.

So reasoning is whole sale price is increased and eventually retail price will increase.
Quote:
D.What percentage of tuna in North America were affected by the bacteria?

No matter the answer of this question (high/low), we are sure about one thing that price of tune has increased. and so the conclusion is not going to change. if you say no this thing will affect prices, we have to assume a lot of stuff. So i called it irrelevant. I see you have made this assumption and fall in trap. well don't use info that is not given.

Hi ShankSouljaBoi,

My reasoning to eliminate (A) is the question stem is specifically asking about "within the next 6 months" and option A is also talking about "eliminate bacteria within next 6 months".. so even if the bacteria do gets eliminated we cannot be assured that tuna supply will get back to normalcy immediately. It may take a few years( or atleast a few months based) for it to since the bacteria has killed of most of the tuna .. the surviving tuna would have to breed and produce more tuna and it would atleast take one season to see an increase ... So a little bit of thought can eliminate A w.r.t E which is more direct.

Let's say tuna based cat food has 3 main components. If tuna got really expensive, and the other two components became super cheap.. the overall price could stay the same or even decrease. Hence E is the stronger choice.

Hope this helps.

If the price of other ingredients in cat food decreases, it may compensate for the price increase due to tuna.

IMO E.

The correct answer choice should validate / invalidate the conclusion on application of variance test.
Applying yes/no test on ans E is simply strengthening / weakening the conclusion.
IMO, there is an error in Ans choice E.
