Critical Reasoning

Cafeteria patron: The apples sold in this cafeteria are greasy. The cashier told me that the apples are in that condition when they are delivered to the cafeteria and that the cafeteria does not wash the apples it sells. Most fruit is sprayed with dangerous pesticides before it is harvested, and is dangerous until it is washed. Clearly, the cafeteria is selling pesticide-covered fruit, thereby endangering its patrons.
Which one of the following is an assumption on which the argument depends?
(A) The apples that the cafeteria sells are not thoroughly washed after harvest but before reaching the cafeteria.
(B) Most pesticides that are sprayed on fruit before harvest leave a greasy residue on the fruit.
(C) Many of the cafeteria's patrons are unaware that the cafeteria does not wash the apples it sells.
(D) Only pesticides that leave a greasy residue on fruit can be washed off.
(E) Fruits other than apples also arrive at the cafeteria in a greasy condition
lsat

imo A.

cafeteria thinks that after harvesting apples are not washed but before reaching cafeteria they washed it , hence they sell as it is

what is oa

, A should be the answer.

IMO it is E as the final conclusionof the argument points towards fruits in general. The case of apple is used only as an example to build a case for the overall conclusion. Please correct me if I am wrong.

I think the answer should be B .

The very first line states : The apples sold in this cafeteria are greasy.

No where in the passage dose the author says that pesticides make the fruit greasy .

The conclusion states : the cafeteria is selling pesticide-covered fruit, thereby endangering its patrons .

So to successfully draw this conclusion the author should have assumed that pesticides causes the apple to be greasy .

Option E is in correct as the conclusion talks about a single Fruit , and from the passage we can say the fruit is apple . But we can not say any thing about other fruits .

Option (A) is incorrect as it says the opposite of what is stated .

The passage clearly states that the fruits are delivered unwashed and it sells unwashed fruits .

Please correct me if I am wrong.

+1 for B.

Greasy and pesticides should be linked with each other for the argument to stand.
If we put B to denial test, we come to know that - had the apples were not greasy, ( i.e. if the pesticides would hadn't left greasy residue) no further investigations would had been made to check why they are greasy ... and hence no conclusion that pesticide covered fruits (so called greasy) are sold.

B

what's is OA?

think it is A .
The conclusion here is :the cafeteria is selling pesticide-covered fruit.
We are looking for an assumption here

look at the following sequence of statements
=> Most fruit is sprayed with dangerous pesticides before it is harvested
=> the cafeteria does not wash the apples it sells

the conclusion hence assumes that the fruit is not washed before it reaches the cafeteria

OA pl.....

IMO A

MY PICK IS "B". don't overlook the word "THOROUGHLY WASHED" IN "A". its enough to eliminate this option.

+1 for B.

Grease and pesticides have to be connected for the argument to hold.

IMO B. OA plz.

I think the ans should be A. This is the only options which works best with the negation...!! pls post the OA

conclusion : the cafeteria is selling pesticide-covered fruit

premise 1 : The apples sold in this cafeteria are greasy when they are delivered to the cafeteria.
premise 2 : the cafeteria does not wash the apples it sells


if the assumption is A and you negate it :

(A) The apples that the cafeteria sells are thoroughly washed after harvest but before reaching the cafeteria.

the patron can still make his conclusion. He'll say that, though the fruits are washed after the harvest, the greasy material still remains on the fruits and they are in the greasy condition when they are delivered.

However, if you negate B :

(B) Most pesticides that are sprayed on fruit before harvest DO NOT leave a greasy residue on the fruit.

will he be able to conclude that pesticides are the reason for greasiness ?

HTH.
