<h3 /><h3>What were crude stone tool?</h3>
Any tool that is partially or totally fashioned out of stone is considered a stone tool in the broadest definition. Even if there are still societies and cultures that rely on stone tools, most of them are related to extinct prehistoric (especially Stone Age) cultures.
Archaeologists frequently research these prehistoric societies, and the examination of stone tools is known as lithic analysis. To deepen our understanding of the cultural ramifications of stone tool use and production, ethnoarchaeology has been a useful research field.
Arrowheads, spearheads, hand axes, and querns are just a few examples of the numerous tools made from stone throughout history. Stone can be ground into tools or it can be shaped by a flintknapper into knapped implements.

Answer:
C) None of the $5,000 should be included in gross income.
Explanation:
During 2016, Sarah's itemized deductions (other than the stolen silverware) were only $2,000. If Sarah wanted to deduct the stolen silverware, she could have taken a casualty loss = $6,000 - $100 - $3,000 = $2,900. Her total itemized deductions would equal $2,000 + $2,900 = $4,900.
But during that year, Sarah should have opted for a standard deduction of $6,300 which is higher than her itemized deductions. That means that Sarah didn't claim any deduction for her silverware, so any money received from the insurance company should not be included in her gross income.
