we are given some employees (Eat lunch in BA) --> have office
from this you are saying, it is an inference that some have office and yet do not eat lunch in BA
but this inference is possible only if we have some employees (who have office) --> eat lunch in BA
but we do not have this relationship as per the stem
say 100 eat lunch in BA, of which 40 have office, we can say there are only 40 employees who have office in total
in this case, all employees with an office eat lunch in BA
I do not understand if from B, it follows whether some employees have office --> not eat lunch in BA
Please if some expert can help

Every employee who takes public transportation to and from work eats lunch in the company break room. It follows that some employees who have their own office do not take public transportation to work.
The conclusion of the argument follows logically if which of the following is assumed?
(A) Some employees who do not have offices eat lunch in the company break room.
(B) Some employees who eat lunch in the company break room have an office.
(C) Every employee who eats lunch in the break room has an office.
(D) Some employees who do not have an office do not eat lunch in the company break room.
(E) Every employee who eats lunch in the company break room takes public transportation to and from work.
OFFICIAL EXPLANATION
Answer: B
STEP 1: Read the question and identify your task.This is an Assumption question. The question asks which answer makes the logic of the argument successful.
STEP 2: Read the argument with your task in mind.In the argument, despite the claim that the second statement “follows” from the first, it does not actually do so.
STEP 3: Know what you’re looking for.Therefore, you must find the assumption that, when inserted between the first and second statements, will make the conclusion work.
STEP 4: Read every word of every answer choice.Answer A ignores the condition of having or not having an office and thus does not help the conclusion. Answer B seems to meet your needs. Since every employee who takes public transportation eats lunch in the company break room, it follows that if some employees who eat in the company break room have an office (as stated in answer B), then there are some employees with an office who do not eat in the break room and thus do not take public transportation. Answer C results in every employee with an office taking public transportation, which contradicts the conclusion. Answer D does not lead to any conclusion involving those who have an office or whether they take or do not take public transportation. Answer E tells you something about those who eat in the break room but nothing about those who have an office or whether they might or might not take public transportation. Thus, the correct choice is answer B.
