Deep tillage is even more deliterious to the world's topsoil supply than previously believed. For example, farmers who till deeply are ten times more likely to lose topsoil to erosion than are farmers who use no-till methods. Results like these make it clear that farmers who now till deeply should strive, by using other topsoil aeration techniques, to incorporate no-till methods instead.

The argument depends on assuming which one of the following?

A. Topsoil erosion does not make farmers want to till more deeply.
B. In deep-tillage farming, the deeper one tills, the greater the susceptibility to topsoil erosion.
C. Tilling by any method other than deep tillage is not a viable option.
D. The most expensive farming methods employ topsoil aeration techniques other than deep tillage.
E. On average, topsoil that is no-tilled is more aerated than topsoil that is tilled deeply.

C.Farmers are already aware that deep tilling techniques are harming their top soil

Still they continue to use the old tilling method assuming that other methods available are not so viable.

I got A as my choice too, but dont understand why it is wrong. :-) Also, where does it imply, in any angle, about the viable methods of tilling?

A cannot be the option, as it suggests that farmers are reluctant to use deep tilling method in their fields,but the entire paragraph is contrary to the same and it points to the fact that farmers are still using deep tilling which causes soil erosion.

Thanks for helping me understand the right choice, Goalset.
But, let me ask one more thing with this regard - how come we assume that any of top soil aeration techniques (as mentioned in the last time) are not viable methods of deep-tillage?

No problem,Macsen.

In the last statement of the paragraph the author has used the word strive which means to try very hard.

Deep tillage causes soil erosion on the farmers own land and still they are not using the other aeration techniques and the author believes farmers have to strive hard to start using them which means they must be non-viable to the farmers(they could be expensive or inaccessible).

I hope this helps.

There is a argument presenting a case for use of non tilling method for aeriation.
So what can be the fact based on which author is stressing her point .
A ) yes could be as she is trying to stop them as they don’t care about top soil erosion
B ) this info cannot be concluded
So I hope it’s A) why its not is bit beyond me

C .
A X because qn is already stating that some farmers are doing that for better aeration but it is suggested but it suggested to diverse the method. It is nowhere implied that erosion is causing as disincentive to the farmers and are not able to do so.

conclusion : farmers should incorporate no till methods in place of deep till methods by using other top soil aeration technique
premise : farmers using deep tillage are ten times more likely to loose top in comparison to non tillage method

what if there being a case tht ""to prevent top soil erosion, one has to till deeper . Thus a possible assumption here would negate this answer choice and that's what option A does. So in my opinion A
