QUES: Inorganic pesticides remain active on the surfaces of fruits and vegetables for several days after
spraying, while organic pesticides dissipate within a few hours after application, leaving the
surface of the sprayed produce free of pesticide residue. Therefore, when purchasing from a
farm that uses inorganic pesticides, one must be careful to wash the produce thoroughly before
eating it to prevent the ingestion of toxins. But one need not worry about ingesting pesticides
when purchasing from farms that use only organic pesticides. The argument above assumes that
• Consumers are aware of the origins of the produce they purchase.
• Produce from farms that use organic pesticides reaches the consumer within hours after it is
picked or harvested.
• No farm uses both organic and inorganic pesticides.
• No pesticide is capable of penetrating the skin of a fruit or vegetable.
• The use of either type of pesticide does not increase the cost of produce.

The answer is D. Though C seems correct, why is A incorrect? my explanation:if consumers are not aware of the origins how would they choose organic/inorganic

Hello,

The question that you posted has been discussed here: https://gmatclub.com/forum/inorganic-pe ... 98929.html

Choice A says that consumers are not aware of the origins of the produce. --> The origins of the produce has nothing to do with organic or inorganic use of pesticides and pesticides consumption. So if you read the conclusion: "Therefore, when purchasing from a farm that uses inorganic pesticides, one must be careful to wash the produce thoroughly before eating it to prevent the ingestion of toxins. But one need not worry about ingesting pesticides when purchasing from farms that use only organic pesticides." -- Origins of the produce doesn't affect the conclusion. Even if a consumer doesn't know the origin, he/she can still ingest the pesticides that are present in produce of an inorganic farm. This is NOT a valid assumption. It's IRRELEVANT.

If you negate choice D - Some pesticides are capable of penetrating the skin of a fruit or vegetable. - this breaks our conclusion, because now whether the pesticide was organic or inorganic, it doesn't matter. Because in both cases there is a possibility that the pesticide will penetrate into the skin, and thus one will be exposed to pesticides even if they are eating from an organic farm.

Hope this helps!

Thanks alot! Yeah D seemed quite obvious but I just wanted to confirm why A isn't the answer. And is this a 500/600/700 level question in your opinion?

Sure. I would say this is a 650-700 level.
