A study undertaken in Sweden found that, when people worked for six hours a day, they tended to be more productive and take fewer sick days than when they worked for the more traditional seven to eight hours per day. Therefore, for companies seeking to maximize profits, it would make sense to have more workers, each of them working for six hours rather than for seven to eight hours per day.
Which of the following must be true in order for the above conclusion to be correct?
A) People who work for six hours per day generally have more energy for managing various aspects of their lives than is had by people who work for more hours per day.
B) Financial gains achieved by having people work more productively for fewer hours per day would exceed the costs of hiring additional people to make up for the reduction in hours worked by each person.
C) People who go from working eight hours a day to working six hours per day generally report that they experience reductions in stress and increases in job satisfaction.
D) It is always the case that a reduction in the number of hours per day a person works results in an increase in that person's productivity.
E) Most workers would prefer working for only six hours per day over working seven to eight hours per day.

Target Test PrepHey Mikare,
Let's first understand the question. It is essential that we understand what the question is asking, since a lot of options in CR make sense on their own but are incorrect with regards to the question asked.
The question tells us that a study shows people with 6 hour shifts are more productive than people with 7/8 hour shifts. If a compan wants to
maximise profits should it hire more workers with 6 hour shifts.
If company hires more workers it has to pay more in salaries, the only way such an arrangement can be profitable if they still save money with increase in productivity after accounting for additional expenses because of the addditional hiring
Therefore the correct option is B
