Answer:
Stone were used
Bone
Explanation:
Throughout the Paleolithic, humans were food gatherers, depending for their subsistence on hunting wild animals and birds, fishing, and collecting wild fruits, nuts, and berries. The artifactual record of this exceedingly long interval is very incomplete; it can be studied from such imperishable objects of now-extinct cultures as were made of flint, stone, bone, and antler. These alone have withstood the ravages of time, and, together with the remains of contemporary animals hunted by our prehistoric forerunners, they are all that scholars have to guide them in attempting to reconstruct human activity throughout this vast interval—approximately 98 percent of the time span since the appearance of the first true hominin stock. In general, these materials develop gradually from single, all-purpose tools to an assemblage of varied and highly specialized types of artifacts, each designed to serve in connection with a specific function. Indeed, it is a process of increasingly more complex technologies, each founded on a specific tradition, that characterizes the cultural development of Paleolithic times. In other words, the trend was from simple to complex, from a stage of nonspecialization to stages of relatively high degrees of specialization, just as has been the case during historic times.
In the manufacture of stone implements, four fundamental traditions were developed by the Paleolithic ancestors: (1) pebble-tool traditions; (2) bifacial-tool, or hand-ax, traditions; (3) flake-tool traditions; and (4) blade-tool traditions. Only rarely are any of these found in “pure” form, and this fact has led to mistaken notions in many instances concerning the significance of various assemblages. Indeed, though a certain tradition might be superseded in a given region by a more advanced method of producing tools, the older technique persisted as long as it was needed for a given purpose. In general, however, there is an overall trend in the order as given above, starting with simple pebble tools that have a single edge sharpened for cutting or chopping. But no true pebble-tool horizons had yet, by the late 20th century, been recognized in Europe. In southern and eastern Asia, on the other hand, pebble tools of primitive type continued in use throughout Paleolithic times.
The answer is C. The Civil war began in 1861 between northern and southern states.
This was due to conflict over slavery’s appearance in western land, the westward expansion, and the fear of the loss of rights!

Solitary confinement holds an individual prisoner in a cell alone, with no contact with other inmates. Prisoners are subjected to solitary confinement if they are considered to be a dangerous threat to others in the general prison population, especially as an added level of punishment if they have acted violently while in prison.
Solitary confinement takes a toll on a prisoner's mental health. Dealing appropriately with mental illness continues to be a problem in prisons in the United States. A 2010 article in The Journal of the American Academy of Psychiatry and the Law described how solitary confinement poses a challenge for medical ethics. The authors summarize: "In recent years, prison officials have increasingly turned to solitary confinement as a way to manage difficult or dangerous prisoners. Many of the prisoners subjected to isolation, which can extend for years, have serious mental illness, and the conditions of solitary confinement can exacerbate their symptoms or provoke recurrence."
