The correct option is B) Stone, Bronze, Iron
There are three ages: Stone Age, Bronze Age and Iron Age. These ages are divided chronologically according to the material with which tools were created: We have the Stone Age in first place since stone was used to make implements. This age is a pre historic period between 8700 and 2000 BCE. In the second place we have the Bronze Age, in which bronze was mainly used to create tools. During this age, early characteristics of urban civilization were found. And finally, we have the Iron Age. During this period, tools and weapons were made of carbon steel (ironworking).
The system of dividing the ages in 3 categories was created by C.J. Thomsen in order to classify objects according to the material with which they were created.
The third estate was made up of middle and lower class of the French population, making 98% of the total population. The other two estates were the Clergy (religious institutions) and the Nobility, the first and second estates respectively. Each group met and were able to vote and discuss the direction of the country. After the Seven Years War, the French economy was decimated and the third estate suffered reparations as the other two estates did not have to pay taxes and were granted certain privileges. Because of the two estates not being tasked with any burdens, the third estate was constantly outvoted and out-voiced by the other two, and this caused a strong desire for a political change from the current circumstances that made it difficult for the third estate to thrive and live.
