In my opinion consider
X = employee
Y: public transport
Z: lunch at company break room

Now for conclusion consider
P: some employees
Q: own office
R : don’t take public transport

The only missing link is between p and z to conclude hence option b is correct

This official LSAT question is very confusing and seems just too hard, breaking all my confidence. I am not able to arrive at the assumption as stated in option B despite thinking for more than an hour. It will be really helpful if you can please elaborate, preferably with an example. Thank you in advance.

GMATNinja - Can you please guide? I'm not able to arrive at the assumption as stated in option B.

I am unable to figure out why it is necessary to assume "some employees who eat lunch in the company break room have an office". Even if no employee eats lunch in the company break room but has an office, we can still have employees who would not use public transport. All employees who have an office may not use public transport (only among those who are without an office we can have employees using public transport and employees not using public transport).

Hi Pankaj.

I did a little research and found that this question is not an official LSAT question but rather a low quality third-party question from a third-party practice test.

In other words, it appears to be a ridiculously busted question such that there's no actual rationale for the credited answer.

Thus, you don't need to worry about this question.

Wow! You would have no idea how relieved I am feeling after reading your post. I have been consistently thinking for the last 3 hours now that my "assumption" section needs re-study, as I have exhausted all OG practice questions. I often get trapped in the last two options, hence I thought of moving to LSAT 700 level questions for practice. Thank you so much for your efforts and response here. :please:

Sure thing, Pankaj.

The question was bugging me as well.

Meanwhile, since you have run out of OG practice questions and often get trapped in the last two options, it sounds as if you are answering the questions too fast and not giving yourself time to learn. So, you may get some key insights that you could use to improve how you prepare for GMAT verbal from this post.

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.
­
Given, "Since every employee who takes public transportation eats lunch in the company break room", which means those eating in the company break room have an office. Now, if you take public transport = you eat at the company break room. But the reverse is not true i.e. you can eat at the company break room but may not take public transport - absolutely fine and still you have an office. So, we can say that some employees who eat lunch in the company break room have an office. Option (B) is correct.­

Option B: Some employees who eat lunch in the company break room have an office. What If those people all take public transportation, then the final conclusion can not be drawn.

hi can anyone show the answer in venn diagram? It will be helpful. I am quite confused
­Venn Diagram is useful, when pre-conditions are given and you r told to findout the conclusion, here conclusion is given. And one condition is certain. The set of people having lunch in the comapny breakroom is a superset to the set of people using public transportation to work.
Rest venn diagrams would vary depending upon pre-conditions, you have to findout the pre condition, there can be many pre-conditions like this one
" Some people who have their own office do not take lunch in the company breakroom" , 

that would lead to same conclusion. ­

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.

Please see Marty's posts above and disregard this illogical question! Folks, this thread ought to be locked or taken down.
