(A) Companies that offer the most vacation time have the least productive workforces.
The is false as said in the argument "no correlation between productivity and vacation time. "



(B) A worker's productivity depends more on his or her salary than on his or her amount of allotted vacation time.
Can't be sure, there may be other factors which affect productivity other than vacations or salary.


(C) Companies that do not have the least productive workforces do not offer the most vacation time.
Again can't be sure as argument refutes any co-relation between vacation and productivity.


(D) Comparisons between the productivity of companies in the same field are often unreliable.
out of scope


(E) Productivity gains may not result from dramatic cuts to vacation time within a company.
Correct. It correctly interprets the argument as productivity gains cannot be achieved by cutting vacation time.


OA plz.

+1 for E.

IMO: E
A) Companies that offer the most vacation time have the least productive workforces.
--The argument says its not correlated


(B) A worker's productivity depends more on his or her salary than on his or her amount of allotted vacation time.
--We know from argument, productivity doesnot depend on vacation, but what it depends on is not discussed, might be productivity is never affected by anything

(C) Companies that do not have the least productive workforces do not offer the most vacation time.
--. Companies that do have the least productive workforces do offer the most vacation time. This is not known from the argument


(D) Comparisons between the productivity of companies in the same field are often unreliable.
-- Comparison between companies is defferent field is out of scope

(E) Productivity gains may not result from dramatic cuts to vacation time within a company.
-This can be infereed as know that productivity doesnot depend on vacation.
Also note" May" is not extreme, so looks good

OA is E
