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

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

(B) Produce from farms that use organic pesticides reaches the consumer within hours after it is picked or harvested.

(C) No farm uses both organic and inorganic pesticides.

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

(E) The use of either type of pesticide does not increase the cost of produce.

OA is D

can you explain? I got C.


I pick C as well :((, but I understand now why it is wrong.

The conclusion only focus on "farms that use ONLY organic pesticides", so farms that use both type of pesticides are out of scope.

D is correct because the Arguments concern with the Ingestion of Toxic, we only have talked about the toxic on the surface of the apple, what if Toxic got inside the skin? D address the issue.

Even I was inclined to pick C ...but somehow read that
"Therefore, when purchasing from a farm that uses inorganic pesticides," .... so consumer is buying from the farm and not from the market ...so he can knows....

hence I picked D ...

Between C and D.

Let's see

There are 2 types of farms as stated:

1. Farms that use inorganic pesticides - consumers worry about washing them

2. Farms that use only organic pesticides - consumers don't worry about washing them

What if there is category 3 farms that use both organics and inorganics contrary to C. Such farms must not be included to farms 2 because farms 2 use organics only. So, consumers should count them as farms 1 and worry about washing them.

There is no need for an additional assumption that eliminates possibility of such farms, it can be read from premises that such farms should be related to farms 1.


Eliminate C.

The conclusion of the argument is that one need not worry about ingesting
pesticides when purchasing produce from farms that use only organic pesticides.
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.

The key word over here is 'ingesting'. If organic pesticides dissipate within hours of use, they lose their efficacy. Thus there is no reason for farmers to use them. However it is possible that the organic pesticides may penetrate the fruit to an extent and hence be effective. If u wash or don't wash, you are still going to ingest organic pesticides albeit harmless quantity.

I have trouble with D because I think that the skin of the fruit is out of scope for this.
If organic pesticide was used and it penetrated the skin, who is to say that it will not
just disappear as if it did not pierce the skin?
Why do we assume that if it got into the fruit, it will not be able to get out?

B cannot be the assumption as it weakens the conclusion.
if the fruits sprayed with organic pesticides reach consumer within hours of harvesting then the pesticides are still present and they cannot be eaten without being washed.

the correct answer is D.

Hi Ron,

The key word in the passage you have missed is 'surface' - so the passage does only talk about the effect that organic/inorganic have on the surface of the fruit.

So... in D, there is clearly something different at stake, that is to say the pesitcides below the surface.

Does that make sense?

Hi James
It does make sense, but my question is another...
When I approach statements like this, I am inclined to think that it is out of scope...
Since there is no mention of what happens underneath the surface of the fruit, why is this not
out of scope?
When do you decide that new information brought forth is out of scope and when do you decide that it
is not out of scope?
Is there any generalization that can be made?

Hi Ronr,

Fair question.

My advice here, is to be super attentive when reading the 'question' (as opposed to the passage itself). Then spending 20/30 seconds working out exactly what that means before charging on.

So, in this case the question is:

The argument above assumes that


So the first thing to do is to work out what the 'argument' is. I.e. what is the argument the person is making, this is likley to be the conclusion. In this passage that phrase is:
But one need not worry about ingesting pesticides when purchasing from farms that use only organic pesticides.


With that as the argument, it's clear that the argument depends on (assumes) that there are no pesticides under the skin.

Does that help?

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

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.
