I am going to give it a shot.

Evidence:

Inorganic Pesticides (I.P): remain on the surface of the fruit for days.
Organic Pesticides (O.P): is gone after a few hours and leave the surface free of Pesticides (P).

Conclusion:

when buy a I.P. fruit, one must wash it carefully to prevent eating poison. But one need not to worry about eating poison when buying only the O.P. products.

A. can't be right, because the origin of fruits from doesn't help the conclusion that weather the customers must wash the fruit or not.

B. kind of weaken the conclusion, depending on the situation. If the fruits reach the customers let's say after 1 hour of picking and delivering, then the customers need to wash both kind of fruits, because the P. is still on them.

C. can't be right, because this is part of the conclusion " use only organic pesticides"

E. out of scope, costs of production can't affect weather to wash the fruits or not.

D is the correct choice (in my opinion). First of all, notice how all the evidences are related to "surface" of the fruit, therefore, inside must not contain P. in order to support such conclusion. Secondly, if the author doesn't agree with this assumption, then the conclusion is not valid, because consumers will eat poison no matter what (wash or not wash the fruit).

In my opinion, This method really takes awhile to think about, if anyone have a shorter way to reach the answer please let everyone know.

IMO: (B)

The conclusion assumes, produce picked from farms using organic pesticides get to the consumer after enough time has passed for the pesticides to wear off. If enough time has not passed then the pesticides may still be on the produce.

I originally thought (A) was the answer but the passage seems to state explicitly purchasing produce from farms that use one type of pesticide instead of another.

mastbombay wrote: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.


Please explain ur reasoing.............

will post OA tomorrow

D is my pick.
A- the origin does not matter; what matters is whether organic or inorganic pesticides are used.
B-Does not matter to the argument
C-The argument clearly mentions 'only organic'
E-Out of scope.

I like answer (A)

If the consumer can not determine the origin, then the conclusion falls apart....right?

Travis_1234567890:

I think A meant the following:

"This batch of apples is from Florida, and that batch is from California." customers can know where the apples are from, but they won't know what type of pesticides were used, and weather to wash the apples or not.

Good point Eric-

I was thinking of origin as...

Farm that uses Organic pesticides v. Farm that uses Non-Organic pesticides.


This is a tricky one, I look forward to the OA

imo:D...

OA??
Explanation if its d OA

I will go with Answer A

The argument says that customers have to be careful when purchasing from a farm that uses inorganic pesticide. Additionally, it also says that the customers need not worry if they are buying produce from a farm that uses only organic pesticide...

So definitely, the argument assumes that customers are capable of identifying the origins of the produce...If customers are unable to identify the origin of a produce how would they know whether the produce needs to be cleaned or not?...

I will go wit "B".
As passage clearly says "Organic pesticides evaporates after few hrs of application and conclusion says produced should be washed before eating if its inorganic but not if its organic". This clearly means organic products reaches consumer after few hrs it is picked or harvested.

I am with A.

Thanks mastbombay for this excellent Q.

The OA for this question is D.

Explanation (from TestMagic): Negate D.
"Pesticide is capable of penetrating the skin of a fruit or vegetable."
This breaks down the entire argument. In this case, consumers should get worry about ingesting pesticides when purchasing from farms that use only organic pesticides.

OA is D. If we negate D then the conclusion of washing the produce thoroughly before using falls apart.

The same reasoning as banker1

Answer is clearly D here.
