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 seems best: Tilling by any method other than deep tillage is not a viable option.

the ARGUMENT is contending that farmers who now till deeply should strive, by using other topsoil aeration techniques, to incorporate no-till methods instead.----->there by making an assumption that Tilling by any method other than deep tillage is not a viable option.

Use negation technique only (c) remains -

Tilling by any method other than deep tillage is a viable option
Quote:
Deep tillage is even more deliterious to the world's topsoil supply than previously believed........ farmers who now till deeply should strive, by using other topsoil aeration techniques, to incorporate no-till methods instead.

If other viable method of tillage are avalable why farmers are still using deep tillage method and why should they strive to use other aeration techniques ...

The entire reasoning falls apart , so correct answer is none other than (C)

The argument concludes that the farmers who till deeply should incorporate no-till methods. The author has taken into consideration only the two extremes deep till versus no-till. So he assumed there can be nothing in between which is correctly identified in "C". "B" restates the fact. So it cannot be a necessary assumption."A" states a conclusion. Again it is not a necessary assumption. Assumption is the missing link between fact and conclusion. Hence the answer is "C".
