KUDOS
while purchasing from a farm consumers offered two options to avoid the ingestion of toxins:
in the case of inorganic pesticides, wash the product thoroughly
and in the case of organic ones, no need to worry about ingesting pesticides
the argument have few assumptions
1- the consumer can know the type of pesticide used in that farm
2- pesticides can affect just the surfaces of the product.
.
.
The argument above assumes that

A Consumers are aware of the origins of the produce they purchase. the argument specifies "when purchasing from a farm"
B Produce from farms that use organic pesticides reaches the consumer within hours after it is picked or harvested. the time the product reaches the consumer can be related to the usage of organic pesticides. the important point is that we need just few hours after the application of organic pesticides not after it picked or harvested
C No farm uses both organic and inorganic pesticides. using both pesticide is not an issue bcz in this case the consumer can wash it thoroughly
D No pesticide is capable of penetrating the skin of a fruit or vegetable. this option is matched with prethinking #2. if either pesticides can penetrate the skin of product then simply by washing it the consumer cannot avoid the ingestion of toxins
E The use of either type of pesticide does not increase the cost of produce. the cost is irrelevant to the argument

premise for inorganic apple

1) Inorganic pesticides remain active on the surfaces of fruits and vegetables for several days after spraying


premise for organic apple

organic pesticides dissipate within a few hours after application, leaving the surface of the sprayed produce free of pesticide residue


there might be several assumptions here for conclusion to prevent the ingestion of toxins[b]

a) for inorganic apple
assumption are
1) washing cleans all the pesticide on inorganic apple
2) there is a tag on the apple so that customer knows that this is inorganic apple
3) process of pesticide doesn't damage the skin and penetrates inside the apple pulp

if we negate any if these assumptions- conclusion breaks- means you can't prevent the ingestion of the toxins


b) for organic apple

assumption are
1)consumer doesn't eat the very fresh apple, eats it after few hours of plucking
2) consumer knows whether he is picking the organic or inorganic ( it is given in the premise that consumers knows from which farm he is picking the apple, so this option or option A is out)
3) process of pesticide doesn't damage the skin and penetrates inside the apple pulp


[b]
conclusion is
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.

I am quite confused with A and D. I understand why D is correct but A is a potential answer as well.
If the customer cannot distinguish whether the produce contains organic or inorganic.. How will he make a decision to wash or consume ? He should be aware of the source of the produce.
Also as someone mentioned, we are concerned about the toxins on the surface.

The basis for that claim is the fact that organic pesticides leave the surface of
produce within a few hours of spraying. In order for this argument to be valid, we
must assume that the organic pesticides do not harm the produce in any lasting
way.
(A) This is unrelated to the argument since the conclusion speaks about not
having to worry about ingesting produce on which only organic pesticides were
known to be used.
(B) If anything, this statement runs counter to what the argument is saying. If
produce that has been sprayed with organic pesticide reaches the final consumer
within hours after it is picked, it is possible that the consumer does need be
concerned about the pesticides.
(C) The conclusion of the argument is already limited to those farms which use
"only organic pesticides."
(D) CORRECT. If a pesticide is capable of penetrating the skin of a fruit or
vegetable then, while the organic pesticide will dissipate from the surface of the
fruit in a few hours, it may remain inside the fruit. The author of this argument
assumes that the pesticides cannot penetrate the skin.
(E) The issue of cost is unrelated to the argument's conclusion about pesticide
residues.


Can you please tell how the conclusion is only restricted to Organic Pesticides. I see a conclusion marker "therefore" for the last two sentences.

I have question regarding B
If instead of only organic pesticide sprinkled fruits , inorganic pesticide sprinkled fruits also reach market after plucking within an hour .
Will it then be a valid assumption?
Please help

From the replies, I see that the conclusion is :
"But one need not worry about ingesting pesticides when purchasing from farms that use only organic pesticides."

However, from my understanding the conclusion includes both of these statements:
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.

Could someone help me understand what am I missing here? Thanks.

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

A Consumers are aware of the origins of the produce they purchase. -Out of scope. We are worried about the ingestion of the pesticides.
B Produce from farms that use organic pesticides reaches the consumer within hours after it is picked or harvested. -It is weakening the argument. If fruits reach people within hours then people would need to clean the fruits.
C No farm uses both organic and inorganic pesticides. -Out of scope. We are worried about the ingestion of pesticides.
D No pesticide is capable of penetrating the skin of a fruit or vegetable. -Correct. What if the pesticides could enter the fruit? If it was so, then the fruits would have to be peeled, cleaned and then eaten.
E The use of either type of pesticide does not increase the cost of produce. -We are not worried about the cost.

The argument above assumes that

A Consumers are aware of the origins of the produce they purchase. THE ORIGINS? THIS IS NOT THE SAME AS WHETHER ORGANIC OR INORGANIC PESTICIDE IS USED - WRONG
B Produce from farms that use organic pesticides reaches the consumer within hours after it is picked or harvested. TOTALLY OUT OF SCOPE- WRONG
C No farm uses both organic and inorganic pesticides. EVEN IF FARMS USE BOTH, THIS DOES NOT NECESSARILY MEAN THAT A FRUIT WILL CONTAIN BOTH AT THE SAME TIME. NICE TRY- WRONG
D No pesticide is capable of penetrating the skin of a fruit or vegetable.- NOW IF ITS CAPABLE OF PENETRATING THE SKIN, THEN WHETHER INORGANIC OR ORGANIC WE DO NEED TO WORRY
E The use of either type of pesticide does not increase the cost of produce- THE DISCUSSION IS NOT ABOUT THE COST YOU CHEAP BASTARDS!- WRONG

Hope it helps


for the explanation of choice A
"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 origin(farm) indeed determines whether organic or inorganic pesticide is used.
Please correct me if my understanding is wrong.

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.

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

Falsification: What if the organic pesticides are absorbed by the fruits?

Possible assumption: The organic pesticides do not intoxicate the produce in any way.


The argument above assumes that

A Consumers are aware of the origins of the produce they purchase.
(If the origins mean the farm and the type of pesticides the farm uses ) The argument has mentioned the statement - “when purchasing from a farm…”. So, it means that consumers are aware of the origins of the produce they purchase. This option does not provide any new information.

B Produce from farms that use organic pesticides reaches the consumer within hours after it is picked or harvested.
If the produce reaches within hours after it is picked from the harvested, then the produce may have the pesticide on it. Therefore, the customer definitely needs to worry.

C No farm uses both organic and inorganic pesticides.
Negate: Some farms use both organic and inorganic pesticides.
The negated statement does not affect the conclusion.


D No pesticide is capable of penetrating the skin of a fruit or vegetable.
Negate: Some pesticides are capable of penetrating the skin of a fruit or vegetable.
If this fact were true, then organic pesticides do pose a threat. This information breaks the conclusion and hence the original option can be the assumption.

E The use of either type of pesticide does not increase the cost of produce.
Cost of produce is clearly out of scope.
