The OLEX Petroleum Company has recently determined that it could cut its refining costs by closing its Grenville refinery and consolidating all refining at its Tasberg refinery. Closing the Grenville refinery, however, would mean the immediate loss of about 1,200 jobs in the Grenville area. Eventually the lives of more than 10,000 people would be seriously disrupted. Therefore, OLEX’s decision, announced yesterday, to keep Grenville open shows that at OLEX social concerns sometimes outweigh the desire for higher profits. Which of the following, if true, most seriously undermines the argument given? The argument is :"to keep Grenville open shows that at OLEX social concerns sometimes outweigh the desire for higher profits." A. The Grenville refinery, although it operates at a higher cost than the Tasberg refinery, has nevertheless been moderately profitable for many years.This does not weaken the above. B. Even though OLEX could consolidate all its refining at the Tasberg plant, doing so at the Grenville plant would not be feasible.----->Which is what the company does.It does not show its social concern or anything against it.NO C. The Tasberg refinery is more favorably situated than the Grenville refinery with respect to the major supply routes for raw petroleum.---->Does not undermine it. D. If the Grenville refinery were ever closed and operations at the Tasberg refinery expanded, job openings at Tasberg would to the extent possible be filled with people formerly employed at Grenville.---->Yes.This gives an alternative to closing the plant yet not resulting in job-loss. E. Closure of the Grenville refinery would mean compliance, at enormous cost, with demanding local codes regulating the cleanup of abandoned industrial sites.----------->Even this might be true.This seems better. E seems best.E shows why the company does not close the plant.It gives an alternate explanation for not closing the Plant at Grenville.

47.If m and k are consecutive even integers is k>m? 1). k-1 and m+2 are not consecutive integers 2). k-2 and m+1 are consecutive integers If we assume k>m And test for 3 different scenarios: k=4;m=2 k=2;m=-2; k=-2;m=-4 Then From A: k-1(3,1,-3)and m+2(4,0,-2) gives consecutive Integers.Hence assumption is wrong nd so k Likewise if with above values and k m=4;k=2 m=2;k=-2; m=-2;k=-4 then A: m+2(6,4,0) and k-1(1,-3,-5) are not consecutive.Hence assumption correct.Thus m>k A Sufficient If for the same values and assumption k>m From B: k-2(2,0,-4) and m+1(3,-1,-3) are not consecutive. Thus k Thus D

In the equation x^2 + mx + n = 0, x is a variable and m and n are constants. What is the value of n ? (1) x + 2 is a factor of x^2 + mx + n (2) The equation x^2 + mx + n = 0 has only one real root Statement A gives : x=-2 as a root.Substituting this in the eqn gives: 4-2m+n=0 Or n=2m-4 Not Sufficient From B; If we know that the Eqn has only 1 real root then it is an asymptote. Now such a figure will then have infinte values of m,n.Hence this is not sufficient. Thus E

64.Each of a, b, c, d can be represented by 2^n, where n is positive integer. If 1 1). a+b+c+d=170 2). A*b*c*d=2^16 From A: The powers of 2 are: 2^1=2 2^2=4 2^3=8 2^4=16 2^5=32 2^6=64 2^7=128 2^8=256 Hence the max value of 2^n=128,because any power of 2 less than that won't add to 170. Since d is the greatest of all d=2^7=128. BTW a=2;b=8;c=32 and d=128 B alone is not sufficient.There can be many combinations which give a power of 16. Hence A The

Private Equity In past decades, private equity investors used to compete for exclusive participation in investments. Now, in response to both the growing scale of investments and increased competition to participate, private equity funds often form "clubs" or syndicates and jointly take positions in large investments. This approach allows them to spread some of the risk and also gain access to other investments and opportunities. Which of the following statements by a private equity investor best defines the changing attitude described in the argument above? A "We would rather beat our competition by working with them in order to find out their strengths and weaknesses." ------>No B "In order to keep up with our competition, we should stop investing small and only invest in very large opportunities." --->No C "In order to make sure that we can participate in certain investments, we should expect to cooperate with our competition on occasion." --->keep it D "To avoid taking any risks, it is necessary to stop competing with our former competitors." ---->No E "In response to changing market conditions, we should participate only in investments that allow us to take better positions than our competitors."--->No Will go with C

Surgeries Hospital Z has a high percentage of followup surgeries. Those are surgeries that have to be done after the first surgery is not successful. In most cases this happens when patients are willing to be treated in this hospital, which is considerably cheaper compared to others in the region. Followup surgeries are done at the expense of hospital Z and reduce its income drastically. Which of the following is the best solution to reduce the number of the followup surgeries? a. Hospital Z has to ensure that all its patients know the risks compared to the more expensive options available .No.What if the follow-up surgeries don't drop even after the patients know the risk. b. Hospital Z needs to hire more professional staff without increasing its prices. ------>Seems good.If they appoint better doctors who can perform the work efficiently,follow-up surgeries will not be required at all.The stem clearly says that in most cases 'the first surgery is not successful'.And why is it not successful,probably there are no good surgeons. c. Hospital Z needs to decrease the number of patients it serves. ---->Nothing is mentioned in the stem about the number of patients.What if there were only 10 surgeries per month and even those required follow-up surgeries? d. Hospital Z needs to increase its prices significantly in order to decrease the number of patients. -------->What if Patients stopped visiting the hospital altogether?Cost advantage after-all is the main attraction,quality of work is not. The follow-up surgeries will definitely reduce,since there will be no surgeries at all.But this will not be a good business decision.[banana] e. Hospital Z needs to charge patients for followup surgeries, even if the patients would cover 30% of the cost of these surgeries.------>Will charging patients reduce the number of follow-up surgeries?No.They will infact start doing more such surgeries to make a quick buck. B wins

High school students who feel that they are not succeeding in high school often drop out before graduating and go to work. Last year, however, the city's high school dropout rate was significantly lower than the previous year's rate. This is encouraging evidence that the program instituted two years ago to improve the morale of high school students has begun to take effect to reduce dropouts. which one weakens the argument??? a)There was a recession that caused a high level of unemployment in the city. b)The morale of students who dropped out of high school had been low even before they reached high school. c)As in the preceding year, more high school students remained in school than dropped out. d)High schools in the city established placement offices to assist their graduates in obtaining employment. e)The antidropout program was primarily aimed at improving students' morale in those high schools with the highest dropouts rates. Hi Soni, To answer why is D not correct,sample this. The question stem says:See parts in bold High school students who feel that they are not succeeding in high school often drop out before graduating and go to work. Now,thing is that these guys would have never stayed in the high school long enough to avail the benefits of such a placement cell.They drop out much before that. Hence there must be some alternate reason for their not dropping out.See the part in blue above:What if these guys had no work at all?Or,what if there was a recession that caused job loss?A handles this well and gives an alternate explanation.

Hey Mitzi: Talented,Charismatic and Aspiring seems to be more parallel.Doesn't it? All three are adjectives.After all The actors who aspire=aspiring actors I hope 'aspiring' is not used as verb here.If it is,then Ur option is better.

'select few' is not the same as 'few selected'.D means/sounds as if Some scientists were 'selected' to make this observation.The essence of the sentence is that very few/select few scientists observe this phenomenon.Hope I am clear?
