As a result of implementing an experimental farming system that combined aggressive new fertilization, deep irrigation, and speculative pesticides, the yield on crops at a farm in central California grew consistently and considerably over the past six years. However, yields this year unexpectedly plummeted, causing the farm's owners considerable financial difficulties.
Which of the following statements, if true, best explains the unexpected drop in yield?
A) As a result of a serious and recent economic recession, the market for the products the farm produced shrank in size during the past year.
B) Other farms that began using the experimental system at about the same time also reported an unexpected plummet in yields this year.
C) The central California region where the farm in question is located experienced a drought 9 years ago, 3 years ago, and this past year.
D) A different experimental system, used on a different crop, failed after two years at a farm in Iowa. Scientists later discovered that chemicals involved in this different system slowly poisoned the soil.
E) Significant and sustained increases in agricultural productivity eventually lead to an exhaustion of important nutrients in land.

A) As a result of a serious and recent economic recession, the market for the products the farm produced shrank in size during the past year. Recessions and market conditions do not affect crop yields.
B) Other farms that began using the experimental system at about the same time also reported an unexpected plummet in yields this year. We are not interested in other farms. This is out of scope.
C) The central California region where the farm in question is located experienced a drought 9 years ago, 3 years ago, and this past year. The yield increased for the past six years, which includes the drought three years ago, so this is not sufficient.
D) A different experimental system, used on a different crop, failed after two years at a farm in Iowa. Scientists later discovered that chemicals involved in this different system slowly poisoned the soil. We are not interested in other experimental systems. This is out of scope.
E) Significant and sustained increases in agricultural productivity eventually lead to an exhaustion of important nutrients in land. This is the correct answer. It directly ties the experimental farming system in central California to the decrease in crop yield.

only option E explains the link between experimental farming system to decreased yield which eventually resulted in the sustained increase in agricultural productivity thereby leading to loss of essential nutrients from land

Premise: A new experimental farming system increased the yields fot the past 6 years. But now the yield has plummeted. We need to find a reason for this.
The yield can be reduced by - external factors such as rain, storm or by diminishing effect of the experimental farming system or by any other external factors.
Option E talks on the lines that the effects of the experimental farming system eventually lead to the exhaustion of nutrients in the land. Hence the correct answer.

Narrowed down to D and E.
But knocked off D cause it says " failed after two years at a farm in Iowa " but the case at hand happened at the seventh year, hence what happened at the second year of any experimental process at any other place is Out of scope.

However, yields this year unexpectedly plummeted, causing the farm's owners considerable financial difficulties.
Which of the following statements, if true, best explains the unexpected drop in yield?
A) As a result of a serious and recent economic recession, the market for the products the farm produced shrank in size during the past year. Explanation: IRRELEVANT
B) Other farms that began using the experimental system at about the same time also reported an unexpected plummet in yields this year. Explanation: IRRELEVANT
C) The central California region where the farm in question is located experienced a drought 9 years ago, 3 years ago, and this past year. Explanation: In this case, the farm should have experienced a decline on yield after 3 years of experimental farming system implementation.INCORRECT
D) A different experimental system, used on a different crop, failed after two years at a farm in Iowa. Scientists later discovered that chemicals involved in this different system slowly poisoned the soil. Explanation: This one is a strong contender. However it talks about a different system! Is it necessary to know about a different system to answer this question. Ofcourse no :D Secondly, Its a different experimental system on a different crop. Therefore most cases will have a different result due to factors like location, subject for experiment or even the experimental system itself. Hence INCORRECT
E) Significant and sustained increases in agricultural productivity eventually lead to an exhaustion of important nutrients in land. Explanation: This is very close to the passage. Significant and sustained increase - the yield on crops at the farm in Central California experienced a consistent growth and the process must have removed all the nutrients from the soil for the plant to grow further. Hence CORRECT.
IMO E
