I didn't get E because I thought that the stimulus didn't say that the techniques necessarily help with the lost to evaporation or leakage from irrigation channels. But an expert (Michael from Magoosh if anyone is interested) told me this:

Imagine the opposite is true, only a small amount of water is evaporated, then this would limit the farmers' ability to increase their production by conserving water, i.e. they don't have much flexibility/chance/opportunity to fix problems.

E says "there's an aspect of this problem that is
1) big (more than half),
2) happening right where the crops are grown (it is not talking about any irrelevant factors, fertilizer, labors, etc, and instead it specifically talks about factors (evaporation & leakage) that directly attribute to water supply and shortages.
3) at least potentially under the farmers' control."

hi from what i understand here, the plan is to increase output using water conservation techniques and not to meet the demand. Hence, the answer is D which clearly support the group's plan to increase the output using water conservation techniques. Since avoiding the wastage of water is addressed in E.

You need to strengthen below arguments:

one group of farmers in such a region plans to increase their production by implementing techniques for water conservation.

Therefore, if the plan needs to succeed, it should be some other hidden factors that consume water for un-predicted reasons.


(A) Farmers that can gain a larger share of the food market in their regions will be better positioned to control more water resources. -- Irrelevant

(B) Most agricultural practices in areas with water shortages are water intensive. --- So what? irrelevant

(C) Other regions of the world not facing water shortages are Likely to make up for the reduction in agricultural output. --- Irrelevant

(D) Demand for agricultural products in the group's region is not expected to decline. -- So what? irrelevant

(E) More than half the water used for agriculture in the farmers’ region is lost to evaporation or leakage from irrigation channels. -- Oh yes, that is what we are looking for, there is a leakage that wastes that water, thus, if farmers fix the reason of the leakage, they will reduce the waste of water!

Many agriculturally intensive areas of the world are beginning to encounter water scarcity problems. As a result, many farmers in these areas are likely to reduce their output as the water supply they need in order to maintain production shrinks. However, one group of farmers in such a region plans to increase their production by implementing techniques for water conservation.

Which of the following, it true, would most strongly support the prediction that the group's plan will succeed?

P : water scarcity problems increase -> farmers are "likely" to reduce their output
C : One group plans to increase their production



(A) Farmers that can gain a larger share of the food market in their regions will be better positioned to control more water resources.
-> The farmer group is trying to enlarge the production by implementing a conservative technology. This statement has no information related to such technology.

(B) Most agricultural practices in areas with water shortages are water intensive.
-> Irrelevant. The arguments is already talking about agriculturally intensive areas and water shortage is stated as well.

(C) Other regions of the world not facing water shortages are Likely to make up for the reduction in agricultural output.
-> If this option is true, the group's plan is likely to fail because the gap, which farmers have made by shrinking their supplies, is going to be supplemented by other regions.

(D) Demand for agricultural products in the group's region is not expected to decline.
-> Irrelevant. The topic is concentrated in relation between water supply and production not demand.

(E) More than half the water used for agriculture in the farmers’ region is lost to evaporation or leakage from irrigation channels.
-> Correct. This statement is talking about water conservative technology and supporting that such technology will be helpful in protecting production from water loss.

One group of farmers in such a region plans to increase their production by implementing techniques for water conservation. That means water conservation technique will help in to get more water to crop. How to get more water, either bring some water from other area or save more available water.

Choice E says the same thing. more than half the available water is lost to evaporation. If water conservation will reduce that evaporation, more water will be available for crop.
