For Q.9/ file CR1 
A. to give you more clear explanation let's suppose ( but i think you can use your common sense after understanding) 
-Old postage per issue=x
-new postage per issue=x/3+x=4X/3
-Old issue Quantity.=Y
-New issue Q. =y/2
total cost =postage cost x quantity
Therefore, old cost=xy; new cost=4XY/6 (old cost is more than new cost= the magazine reduces the cost-->increases the profit): eliminate A

B. implies that the customer preference doesnt change. Therefore, it lightly implies that the revenue doesnt change. (but still reduce cost due to the decrease in # issue--> decrease total cost)--> increases in profit: eliminate B

C.Same things as B ( but more strengthen than B)

D. says that the income will be less because previously advertiser will reduce the advertising space(=magazine's company income) by half.--> therefore the decreasing issue quantity produces 2 effects 1)the revenue decreases (due to advertising space , 2) the cost decreases (due to postage cost)= the profit possibly declines. correct.

E. implies that the total cost is reduced ( due to the decrease in postage cost).--> increases in profit

Q.18/file CR2
The brief review: the Salcor receives the financial benefit from encouraging the people to have early treatment for high c. Then, Salcor do not need to insure the later-in-life possible heart attack cost. Salcor encourages Garnet. The conclusion: Salcor employees leave earlier-->Salcor has no financial incentive to do so to Renco. (unlike Garnet)
A. If early treatment is does not help to prevent later stoke, Salcor will not save for compensation cost. -->even strengthen the conclusion that there is no financial incentive to do so to R. (and G).

B. ppl get the treatment on their own.IMO, it is lightly neutral to irrelevant.

C. G hires employees significant # of employee from Renco--> it means that however, if the Renco em. are not early treated, Salcor has to pay for the compensation ANYWAY. (better treat early)--> there is financial incentive to do so now to Renco.--> weaken

D. # of employees is out of scope

E. Age of employee is out of scope

I think i could fall into A in the real test, just like you, since choice A. attacks the premise but may i humbly recommend you to stick with conclusion. I think this is what GMAT try to trick us on the hard Q.

donisback, hope this helps

2.)Take away: Agr. improves the nutritious by encouraging farmers to plant SPK (rich in Beta-->A) Conclusion: good chance of success because 1. main food 2. others contain little betaC.
A is weakening
B is lightly weakening to irrelevant
C. Irrelevant
D. No other varieties of sweet potatoes. In my opinion, this is lightly strengthen (less than E). The conclusion is just say that good chance of success, not become the best-selling of sweet potatoes./no other is quite extreme word.
E. it is simply said that make sure there is no other things that is at disadvantage. =strengthen to the degree that it can be the assumption. Alternative approach, negate E., “ the current potatoes contain important nutrients that SPK lacks” Now, the increase in Beta might not be appreciated by consumers.

3.)Take away: Nubians was at T disease area, but few disease evidences in skeletons. Skeletons have tetracy..(used to make Nubian diet) Conclusion: Tetracy..--> low in T disease.
A.Infectious diseases other than T.--> irrelevant
B.This says that Tetracycline capability is not destroyed via cooking diet./ Yet again, alternatively, negate B. If the Tetracy is ineffective antibiotic due to the cooking process, the tetracy will not be able to be the cause of low disease. 
C.Transmit of disease is quite irrelevant. The conclusion focuses on the relationship between Tetracy and disease.
D.Not necessary. Even though, there is in other items or not, it is not going to affect the conclusion(relationship between Tetracy and disease)
E.irrelevant

Hope that helps. Good'luck on you Gday
