Can this be considered a 700 level because it is very tricky

Thanks



It certainly is a little tricky. Plan/proposal questions are harder to work out as compared with simple weaken questions. Option B confuses you but once you read option C, you can work out that option B is incorrect.
It is between 650 - 700 level.
The important thing to remember here is that you only need to cast doubt, not ensure that the plan fails.

Premise - An overwhelming proportion of the most productive employees at SaleCo's regional offices work not eight hours a day, five days a week, as do other SaleCo employees, but rather ten hours a day, four days a week, with Friday off

Conclusion - plans to increase overall productivity by keeping the offices closed on Fridays and having all employees work the same schedule-ten hours a day

Assumption – All employees are similar in their working habits

Anything which weakens the conclusion is our answer i.e anything which proves that keeping Friday off and working 10 hrs for the remaining four days will not increase productivity

Option C weakens the conclusion and is our answer

Noting this phenomenon, SaleCo's president plans to increase overall productivity by keeping the offices closed on Fridays and having all employees work the same schedule-ten hours a day, four days a week.

Which of the following, if true, provides the most reason to doubt that the president's plan, if implemented, will achieve its stated purpose?

A. Typically, a SaleCo employee's least productive hours in the workplace are the early afternoon hours.
B. None of the employees who work four days a week had volunteered to work that schedule, but all were assigned to it by their supervisors.
C. Working ten hours a day has allowed the most productive employees to work two hours alone each day in their respective offices relatively undisturbed by fellow employees.
D. Employees at SaleCo are compensated not on the basis of how many hours a week they work but on the basis of how productive they are during the hours they are at work.
E. Those SaleCo employees who have a four-day workweek do not take any of their office work to do at home on Fridays.


Responding to a pm:

B is incorrect. If anything, I would say that this information increases the probability that the plan will achieve its desired purpose i.e. the productivity of the people will increase. The employees who work 10 hrs 4 days do not do it on their own accord and according to what works best for them; instead, they do it because their supervisors told them to. Hence, their productivity is higher not because their body works best in this manner and hence they chose to work this way but because somehow, this 10 hrs 4 days schedule increased their productivity. This means that if others are also told by their supervisors to work 10 hrs 4 days, their productivity might increase too.

C says that 10 hrs has allowed people to work alone for 2 hrs. This alone time increased their productivity. If everybody is made to work for 10 hrs, there will be no alone time for anyone. Hence, we would expect the productivity of current 10 hrs 4 day slot people to decrease and the productivity of the rest of the employees to stay the same. Hence the plan will fail.


How can we rule out option D??: If employees are compensated on productivity then all of them must be at the peak of their productivity because every employee wants to be compensated more. so making them work 10 hrs a day for 4 days wont help increase productivity.

Hi aki

You have a problem in determining the conclusion & question stem correctly:

The conclusion is (I rephrased): If all employees work at 10h/day, 4days/week, the company will have highest productivity because all employees work at highest productivity.

Question stem: Which of the following, if true, provides the most reason to doubt the success of the president's plan. ==> It means: Which option demonstrates that the president's plan will NOT be successful.

D: Employees at SaleCo are compensated not on the basis of how many hours a week they work but on the basis of how productive they are during the hours they are at work.

Why D is wrong?

(1) D does not show the probability that the president's plan will be unsuccessful. In fact, D shows that the president's plan may be successful because all employees work at highest productivity. Thus, D does not cast doubt on the president's plan.

(2) Employees work at highest productivity does not mean they can work as long as possible (to get extra bonuses). What if "10h/day, 4days/w" is the limit of employees reaching their peak of productivity?

Hope it helps.

We cannot infer that "all of them must be at the peak of their productivity". Productivity could depend on lots of factors, some internal to the person, some external. Say, the workers make widgets at work. They are paid according to how many widgets are made (productivity) rather than how many hrs they work. How many widgets they make depends on the speed at which they work, the infra available, whether the machines to make widgets are available when they need or do they have to wait etc.
They may not be able to make the maximum number of widgets that they can even if they try their best due to other constraints. They may be able to make even more if they are provided some extra facilities e.g. more machines, more room etc. Hence, its too far fetched to say that since they are paid based on productivity, they are working to their full capacity. Even if it were true, productivity can always be increased by changing/adding/removing/updating some factors.
