### HideShow timer Statistics

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.

A. Consumers are aware of the origins of the produce they purchase.

I am assuming here that they mean origins as what type of pesticide used.

The rest of the 4 are out of scope.

I think best choice is C. If farm start using both organic and inorganic pesticides then this above para about the differences between organic and inorganic pesticides would fall apart. Hence this must be the most basic assumption.

Conclusion: "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 author sites the comparison of the use of pesticide as the premise.

Only assumption A is valid, the other options are out of scope.

the decision comes down to either b or d ...

d was stronger than b ... b says that fruit reaches consumer within a few hours. in that case, consumer may or may not still need to wash it.

here they key of the argument is the consumption of the produce. the argument previously only mentioned that pesticides will stay on teh surface of the fruit, so to go from that to ingestion must mean he is making the assumption that the pesticides dont get INTO the produce.

Tough one.

BCE are irrelevant.

Choice is between A and D. Because the statement is a call for action (while purchasing from ...), I will choose A. But since the entire discussion is about the activity on surface of produce, I think even D could be correct. But again D makes a sweeping statement (no pesticide ...). We are not sure if there are more than two kinds of pesticides ..

I will go for A.

I am with D here.

We already know that consumers know the origins of their foods. They are buying from an organic, or inorganic farm. That is pretty straightforward.

In order to reach the conclusion---> one needs not worry about injesting particles we need to assume that the toxins only stay on the surface. if the toxins seep through, you can still wash the produce but it will still cause you harm.

D must be correct. With out assuming D, the whole argument is invalid.

I'll say D.

If the pesticide is capable of penetrating the skin then the author would not conclude that customers need not worry about ingesting pesticides when they purchase fruits from farms that use only organic pesticides. If pesticides were capable of penetratingthe skin the argument will fall apart.

D. Conclusion is you don't have to worry about ingesting pesticides...from whatever...if ohh by the way the pesticides are in the fruit - you would have to worry about them.

No pesticide is capable of penetrating the skin of a fruit or vegetable.

The assumption is that the toxins are gone and that is why organic is better. But what if the toxins aren't really gone? Then the whole premise is invalid.
