Hey Everyone,
Great work on this. I just wanted to address the way that some people were leaning towards C, so I thought I'd take on all the answer choices in one swoop.
a) work without interruption from other employees.
PROBLEM: The time people come in should not have any effect on whether people get interrupted.
b) consult at least once a day with employees from other companies.
PROBLEM: Consulting with other companies once a day should be easy, as everyone will still be there for at least 6 hours of a typical work day.
c) submit their work for a supervisor's eventual approval.
PROBLEM: Notice the word "eventual". If this implied that the supervisor need to sign off on everybody's work THAT DAY, this might be the correct answer. But the implication here is that the supervisor could "eventually" approve it, which doesn't link it to any specific time.
d) interact with each other throughout the entire workday
ANSWER: Contrast with C. In this case, they use the word "entire". Well, obviously this is going to get in the way of interaction through the "entire" work day. This question really does revolve around the use of the qualifiers "eventual" and "Entire".
e) undertake projects that take several days to complete.
PROBLEM: They'll still be at work 5 days a week, so this shouldn't be a problem.
Hope that helps!
