### HideShow timer Statistics

Twenty years ago the Republic of Rosinia produced nearly 100 million tons of potatoes, but last year the harvest barely reached 60 million tons. Agricultural researchers, who have failed to develop new higher yielding strains of potatoes, are to blame for this decrease, since they have been concerned only with their own research and not with the needs of Rosinia.

Which one of the following is an assumption on which the argument depends?
(A) Any current attempts by agricultural researchers to develop higher-yielding potato strains are futile.
(B) Strains of potatoes most commonly grown in Rosinia could not have produced the yields last year that they once did.
(C) Agricultural researchers often find concrete solutions to practical problems when investigating seemingly unrelated questions.
(D) Wide fluctuations in the size of the potato crop over a twenty-year period are not unusual.
(E) Agricultural research in Rosinia is funded by government grants.

IMO B Since it explains that there's no other reason because of which crops yield decreased.

Whats OA.

(C) Agricultural researchers often find concrete solutions to practical problems when investigating seemingly unrelated questions.
(D) Wide fluctuations in the size of the potato crop over a twenty-year period are not unusual.
(E) Agricultural research in Rosinia is funded by government grants.

Argument Simplified:

Premise 1 : Less potatoes were produced last year in comparison to the amount produced 20 yrs Ago.
Premise 2 : Agricultural researchers have failed to develop new higher yielding strains of potatoes.
Premise 3 : Agricultural researchers were concerned only with their own research and not with the needs of Rosinia.
Conclusion : Agricultural researchers are to blame for this decrease.

Why do we need to develop new higher yielding strains of potatoes ?? Why Agricultural researchers should be blamed ?

(A) Any current attempts by agricultural researchers to develop higher-yielding potato strains are futile. >>> Out of scope >>> Are we talking about the current attempts
(B) Strains of potatoes most commonly grown in Rosinia could not have produced the yields last year that they once did. >>> Strains of commonly grown potatoes could have produced the yield, that's why agricultural researchers were expected to develop new higher yielding strains of potatoes...!!! >>> Correct
(C) Agricultural researchers often find concrete solutions to practical problems when investigating seemingly unrelated questions. >>> Out of scope
(D) Wide fluctuations in the size of the potato crop over a twenty-year period are not unusual. >>> Agricultural researchers should be blamed because they were not able to develop new strains...Though this option is close, but it's nowhere related to the conclusion (Agricultural researchers are to blame for this decrease.)
(E) Agricultural research in Rosinia is funded by government grants. >>> Out of scope
[/quote]

I must say, not a very clean question...!!

what's the OA.

Ans shd b (C) ..

It is assumed that Scientists will find solution to the problem ..

Wat is the OA .. it was quite difficult a question .. worth 700 types ..

Pick C here.
Decrease in harvest is a Practical Problem

Premise holds that agriculchers are concerned only with their own research - related research- i.e. theu investigate related questions.

C states that in order to solve Practical Problem agriculchers must investigate unrelated questions, what they do not do. That's why they failed to develop new solution.

C clearly fills the gap.

B is more of a statement mentioned in the argument. C seems to talk about the assumption.
I'll go with C.

I am also not very convinced with C. But I think C is the best.

Negating B falls apart the premise, whereas negating C falls apart the conclusion. However I dont like the 'unrelated questions' phrase.

my pick is (B)

C does not seem to be totally in line with the argument.

Why is D not correct? I did not get it from nverma's post....
I would have picked D....

B

It is an implied assumption since the author advocates research on higher yielding potato strains. He is thus assuming that the current strain is unable to match the yields that it made 20 yrs ago.

The conclusion states that since researchers are focused on their own research and not a high yielding potato strain, they are to blame for a bad harvest.

Choice C makes it possible that researchers focusing on things other than potato strains can actually benefit the potato harvest and be a good thing. This idea weakens the conclusion. I pick B.

Took some to decide as none of the choices was looking good.When I read the choices again,B seemed the best.

I go with D.

If D is taken into consideration, then this fluctuation in the size of the potato crop over 20 year period is NOT UNUSUAL. So it was expected. Despite expected fluctuation, researchers failed to develop new higher yielding strains of potatoes.

IMO C although its not the best choice i would say.

B is incorrect IMO because it does not effect the solution, it explains well why the output was less but dont see how it affects the conclusion "Agricultural researchers, who have failed to develop new higher yielding strains of potatoes, are to blame for this decrease, since they have been concerned only with their own research and not with the needs of Rosinia."

IMO B. Researchers are blamed so this clearly explains the blame

Choice B for me.

The reason Republic of Rosinia needs researchers to develop new strains of potatoes is because the older strains do not produce high yields anymore.
