Are chipped stones with regular pattern evidence of humans? Yes/No/Maybe. Why? Are Animal bone with hole at one end evidence of humans? Why? Are unmarked, scattered animal bones evidence of humans? Why? Are boulders evidence of humans? Why?

1)Yes, because stone tools are less susceptible to destruction than bones, stone artifacts typically offer the best evidence of where and when early humans lived, their geographic dispersal, and their ability to survive in a variety of habitats

2)Yes because  non- human animal bones have a greater density relative to size; they are less porous and are thicker in cross section than the bones of humans. For example, in humans humeral and femoral cortical thickness is about a quarter of the total diameter compared to about half of the total diameter in animal limb bones.

3)Yes, the bones can tell us not only what kinds of animals humans hunted, but their abundance and age at death, and, in the changes as different layers are uncovered, the impact of human predation on wild populations. ... “[The bones] serve as important proxies for what humans were doing.”

4)Yes, as scientists have discovered what they say is “direct evidence” supporting the theory that Ice Age migrants from Asia traveled down the Pacific Coast, rather than through North America’s interior.A geological study provides compelling evidence to support the hypothesis that ancient humans migrated into the Americas via a coastal route. By analyzing boulders and bedrock, a team shows that part of a coastal migration route became accessible to humans 17,000 years ago. During this period, ancient glaciers receded, exposing islands of southern Alaska's Alexander Archipelago to air and sun -- and, possibly, to human migration.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
