Explanation:
If Sally can paint the office by herself in 5 hours, we can say that in one hour she paints 1/5 of the office.
On the other hand, Lucy paints the office in 4 hours, which means that, in 1 hour she paints 1/4 of the office.
Therefore, to know how much they would paint per hour working together, we are going to sum up the fractions they paint per hour:

Therefore, working together they will paint
of the office in one hour.
Now we can establish a rule of three: if they paint 0.45 of the office in 1 hour, how long (x) will it take them to paint 1.0 of the office?

And therefore 
Therefore, it will take them 2.22 hours to paint the office working together.

Answer: The school board wants you to answer C) Agricultural Revolution, but that is incorrect.
The correct answer would be during the Neolithic Era, so none of the choices would be the right answer.
Explanation: During the Paleolithic Era, which corresponds to the old stone age, people were hunter-gatherers. This means that they obtained food by hunting animals and by gathering fruits, vegetables, and nuts from local plants. So options A and B are pretty much the same thing and incorrect.
Domestication and pastoralism developed during the Neolithic or new stone age when people discovered that, if they took care of certain plants, they would grow again and give them more food. Domestication is not the same thing as agriculture (even though the school system continues to teach it this way).
The Agricultural Revolution actually refers to a much later period in history, during the 18th century in Britain, when traditional agriculture went through a process of transformation. This is way after domestication and pastoralism.
Finally, option D is also incorrect because classical civilizations like Greece and Rome already had full-scale agriculture and had already gone through the process of domestication and pastoralism.
