Guys, I think it is more simple.

It says: "the AVERAGE AMOUNT of OVERTIME per month for the manufacturing division is 14 hrs."

Let's say the manufacturing division has 100 people.
For 99 of them the AMOUNT of OVERTIME is 0.
For 1 of them the AMOUNT of OVERTIME is 14 hrs.

The AVERAGE AMOUNT of OVERTIME for the division will be 14 hrs.

So it simply is D.

Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.

The debater's argument is most vulnerable to criticism on which of these grounds?

(A) It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month.

(B) It takes for granted that if a certain average of amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division.

(C) It confuses a claim from which the argument's conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability.

(D) It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all.

(E) It overlooks the possibility that even if most employees of the corporation work some overtime each month, anyone corporate employee may, in some months, work no overtime.




Here is my explanation for D



Suppose the average overtime in Techahaed is 14 hours.
Does that mean everyone/most people works overtime ?
No ..
But Why?

Few people might work more than 14 hours say even 23 hours ..
and this will reduce the average work hour of the remaining few..

say for 10 people * 14=140 hours work
if 4 people work 24 hours each then it is 96 hours,this will leave
6 people with 44 hours work..44/6=7-8 hours work..No overtime for majorty
that is 6 poeple


Press Kudos if it helps!!

You can safely ignore it.

It helps slightly to reinforce the each month part of the conclusion (Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime). The correct option however, doesn't need this statement. It attacks something more fundamental: if many employees work no overtime, it becomes much harder for us to say that most employees almost certainly work some overtime each month. But if the individual figures are just relatively stable (that is, they don't fluctuate), we don't know whether most are non-zero or not.

Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.


Conclusion -- most employess almost work on overtime
Premise --
1.) most employee work on manufacturing unit
2.) avg of overtime is always from month to month

Basically, we have to weaken this argument..

2 ways to tackle this question

Approach 1 - mean, median and avg method used in quants
It is given in passage that the avg of overtime in manufacturing is 14 hrs, so i want to say that if employess working under manufac divison lets say that
Avg = 14hrs = (sum of working hrs of employees)/(total no. of employees); lets say total no. of employees are 5 and if 4 people are not working overtime like 8hrs per month and so 5th person must work something like 32 hrs to balance the avg of overtime; this means that most employees not working avg overtime which weakens the argument

Approach 2 -- no time to think that much then do it by POE

The debater's argument is most vulnerable to criticism on which of these grounds?

so lets do it by poe and keep our logic (approach 1) on mind while solving

(A) It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month. -- it just the outside information -- typical divison and regard -- so eliminated

(B) It takes for granted that if a certain average of amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division. --- same outside information -- it means that author has taken the fact for granted that most employees must work same overtime -- remember the month avg of overtime is constant -- but it doesnt mean that all employees are working same overtime -- as we dicussed in approach 1 that the avg overtime may fluctuate on employees -- so eliminated

(C) It confuses a claim from which the argument's conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument's conclusion only with a high degree of probability. -- honestly i eliminated this option because "high degree of probability" -- so out of scope -- so eliminated

(D) It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all. -- hold on for approach 2 -- but for approach 1 Bingo -- we got it

(E) It overlooks the possibility that even if most employees of the corporation work some overtime each month, anyone corporate employee may, in some months, work no overtime. -- for approach 2 it is very close to answer -- but it can be eliminated due to if one employee doesnt work overtime then it implies that most employees working some overtime


TBH this was tough question
