The Paleolithic (from the Greek παλαιός, palaiós: 'ancient', and λίθος, lithos: 'stone') means etymologically ancient stone, a term created by archaeologist John Lubbock in 1865 as opposed to Neolithic (new stone). It is the longest period of human existence (in fact it covers 99% of it and extends from about 2.59 million years ago (in Africa) 1 until about 12,000 years ago. the Mesolithic / Epipaleolithic (transition phases) and the Neolithic, the so-called Stone Age, so called because the elaboration of lithic tools has served archaeologists to characterize it (as opposed to the later Metal Age).
The transfer of the Paleolithic to the Neolithic occurs when human history appeared and generalized agriculture and livestock grazing (cattle), giving rise to agrarian societies. Normally, but not necessarily, it is accompanied by pottery work. In the Neolithic appear the first settlements and sedentary human settlements.

Answer: The answer is A: The marginal benefit of completing the project outweighs the marginal cost of the project.
Explanation: The marginal cost will be the cost incurred by the company in trying to complete the big project they acquired. The marginal benefit in this case will be the maximum amount of money they can get from this project upon completion. Thus, for the company to take a decision to halt their ongoing new office building, they have clearly seen that what they stand to gain from the project is huge when compared to just stalling on a new office building. With this decision they can complete the project, continue the new office building later on, and still have a lot of profit after doing so.
