Side by side tests of fruits and vegetables grown using conventional and organic methods have found no significant difference between the levels of key nutrients in the conventionally grown produce and the levels of those nutrients in the organically grown produce.
Thus, there is no reason to believe that there is any health benefit to be derived from eating organically grown produce rather than conventionally grown produce.
Which of the following is an assumption upon which the argument depends?
Argument Analysis:Premise: According to tests --> Nutrients (Conventional Method) ~ Nutrients (Organic Method)
Conclusion: Health benefits from vegetables and fruits grown by either of the methods is same.
Assumption (Prethinking) : 1. Nutrients are the only factor to consider to understand the health benefits.
2. No other factor affects the health benefits.
Options Analysis and POE:Quote:
A. Fruits and vegetables that are grown using organic methods do no taste different from those grown using conventional method.
That is a good thing if the fruits and vegetables taste the same but does that really have an impact on the health benefits? Similar taste is one factor that helps to not distinguish between the two types of fruits but still the harmful effects might exist and these effects are not addressed.
Eliminate A.
Quote:
B. Plants take in nutrients from the soil as a necessary aspect of their growth processes.
Okay. But still we haven't address the health aspect.
Eliminate B.
Quote:
C. Conventionally grown produce does not contain significant levels of health harming chemicals that organically grown produce does not contain.
Brilliant. So, the chemicals used in the conventional method are not harmful. This gives a strong relief to believe that either of the methods will yield the same results for nutrient content and the health benefit.
If we use
Assumption Negation Technique, the negated statement will be
Conventionally grown produce does contain significant levels of health harming chemicals that organically grown produce does not contain.This definitely thrashes the conclusion and makes us believe that Organically grown fruits and vegetables
are indeed healthier than conventionally grown fruits and vegetables.
Keep C.Quote:
D. The differences between the prices of most organically grown produce and those of most conventionally grown produce are not justified.
But cheaper or dearer, as long as the health benefits are better in organically grown fruits and vegetables, we don't care. Also, What do we really mean by
justified? Are Organically grown fruits and vegetables cheaper? Wow. or are they dearer? Uhhhh..
Eventually, pricing doesn't help us understand the health benefits.
Eliminate D.
Quote:
E. The methods in farming organically grown produce tend to be more labor intensive than those used in farming conventionally grown produce.
How difficulty is to produce organically as compared to conventionally is not important. We still don't have any health benefits data.
Eliminate E.
We have a winner in Option C.
