All of these could be a form of bias in a map
I assume that it's a hominid fossil - since it has tools and mostly only hominids are found to use tools (although birds are also known to use tools).
It could be Homo erectus, which lived between 2 million years ago and 70 000 years ago, but more likely it's homo habilis, which lived from 2.5-1.5 million years ago.
The correct answer is - A.) It was hidden under 60 feet of ash for 1700 years.
The city of Pompeii was located on the side of the Vesuvius volcano in Italy. It was not a big or very important city at the time, but it became famous much latter in the future.
After an eruption from Vesuvius, the city and its inhabitants, were all buried under 60 feet of ash. That was a tragic moment in the history, but it is a ''gold mine'' for the archaeologists as everything remained perfectly well preserved, and that was of great help in reconstructing the life of the people in that period of time.

Natural resource economics deals with the supply, demand, and allocation of the Earth's natural resources. One main objective of natural resource economics is to better understand the role of natural resources in the economy in order to develop more sustainable methods of managing those resources to ensure their availability to future generations. Resource economists study interactions between economic and natural systems, with the goal of developing a sustainable and efficient economy.[2]
