A leading cement manufacturer has been having
problems processing manufacturing and delivery
records since it expanded its operations. To solve this
problem, it plans to install a new platform on its
central computing system which will run its tracking
program five times faster than the current system
does.

Which one of the following casts the most serious
doubt on the manufacturer’s plan?

Not all computer platforms can make the
company’s tracking program run more
quickly.

The cost of the new computer platform will
require the cement manufacturer to raise
prices for its products.

The cement company’s computer system
does not have the capability to run the new
platform and cannot be updated.

The company has been increasing sales of
cement by 1.5 percent a month for the past
18 months.

A completely new computer system could
make the program run six times faster than it
does currently.

C is the best answer since it clearly weakens that the system cannot be upgraded any hence cannot be implemented. So the companys would not be completed with this plan.

+1 kudos if U like this post

I did not do the math but only D made sense to me. A and C are contradictory to the stimulus. B is out of scope and E again modifies the stimulus but does not weaken/strengthen.

Expanded operations and processing times are exceeding the original time window

Plans to install a new system 5 times faster.

need to prove that this will not help

So if the increase is multiplying every month for the past 18 months, it is possible that he will still have problems after the new install.

I think it is C.

This is a weaken question. The manufacturer plans to install a new platform on company's existing central computing system expecting that the new platform will process the records five times faster.

But C says that the company's computer system does not have the capability to run the new platform and cannot be updated.

This clearly puts a doubt on manufacturer's plan of installing new platform on existing computer system for faster processing of records.

I would choose C by POE
A contradicts since it is stated that the new platform will be 5 times quicker
B is irrelevant
D sounds good, but we can't assume that the sales will definetly go up in future
E is irrelevant

I agree D is the best

D suggests that the cause lies in somewhere rather than in the platform

the cement company is growing so fast that even if it puts in a new computer system, the company will soon out grow it. I pick D

for all those that picked C, it says in the stem that the company is installing a new computer system

anybody have OA?

The original question states that "it plans to install a new platform on its central computing system which will run its tracking program five times faster than the current system does".

Was there another part of the question that was left out? I don't see where it says a new computer system is being installed, I think the original info clearly implies that a new platform is being installed on the CURRENT computing system. (C) suggests the new platform won't work on the current computing system, I don't see where a new computing system comes in.

In anycase, I vote for (C) as well. Choices A & B presents potential hindrances & side effects to the plan, they're plausible but not as strong as (C), which suggest the plan won't work at all.
For me, (D) & (E) are eliminated right away, since they do not clearly present obstacles that would cast doubt on the plan's feasibility, effectiveness, or benefits. If anything, (D) illustrates the need for some kind of improvement over the status quo, since new orders are likely to increase in quantity & be more frequent.

Out of all current options, (C) creates by far the biggest obstacle to the plan. In fact, if (C) were true, it would highlight the negative aspects of both A and B combined.

now that I have gotten som sleep i think you are right...C seemed to obvious ..didnt trust it

If the system can run new platform, it'll have capabilities to run faster.
