Can someone please explain to me the following questions why the answers are as they were and not otherwise? Thanks
PT17 LR 1 #10
why is the answer A not B? The passage seems to be suggesting that the apples are not washed BOTH after the harvest and before reaching the cafeteria.
PT 20 LR 2 #11
Why aren't both D and E correct? I tried to negate the statement of E and it also weakens the conclusion.
PT 3 LR 1 # 12
why is D correct?the stimulus doesn't state the comparason between the two different plants...

Re: some LR assumption questions..(necessary + sufficient)
I don't have PTs 3 and 17, so I can't help you with questions on those tests.
As for your PT 20 question, answer choice E doesn't have to be assumed because the stimulus never says that John works as a blacksmith only on Friday. Thus, we could negate answer choice E and still arrive at the conclusion. (For instance, John could work as a blacksmith on Monday-Friday and at the insurance company on Monday-Thursday.)

Re: some LR assumption questions..(necessary + sufficient)
I don't have 17 in front of me either, but I'm pretty sure I remember this question well enough to help you.
The way I remember it, the author says that the apples the cafeteria serve are sticky, and that the orchards spray pesticides on the apples before harvest, and the cafeteria doesn't wash the apples they sell, so therefore the cafeteria is endangering its patrons by selling pesticide-covered fruit.
The author is assuming that the apples aren't washed in between the time they're sprayed and when they arrive at the cafeteria--he thinks that because the cafeteria didn't wash the apples, they must still have the pesticide on them, when in fact they could have been washed after they were harvested and before they were delivered to the cafeteria (by the people at the orchard, for example). So the answer choice they're looking for says something like "the apples are not washed after harvesting but before they arrive at the cafeteria", which is what the author is assuming (if the word "but" in the answer choice sounds weird, keep in mind that "but" is logically equivalent to "and").
I wasn't sure what you meant when you said "The passage seems to be suggesting that the apples are not washed BOTH after the harvest and before reaching the cafeteria." "After harvest" and "before reaching the cafeteria" is one period of time, so I'm not sure what you're referring to when you say "both". It just means that they're not washed anywhere in the time period after harvest and before reaching the cafeteria.
I hope this helps.

Re: some LR assumption questions..(necessary + sufficient)
thank you guys, they make much more sense now 
foggynotion: i'm impressed by your super memory :O and what i meant when i said 'both' is that the apples are not washed anytime, neither after the harvest nor before the delivery, which is essentially what the answer choice means in your explanation...i first interpreted it as saying it's not washed after the harvest, but it's washed before the delivery. i never knew that 'but' can mean 'and' in this context. why are they logically equivalent?
