What state essentially experienced a civil war a few years before the civil war broke out?

The correct answer is Kansas.

In 1854, Congress passed the Kansas-Nebraska Act. This law allowed citizens of Kansas to vote on whether or not they wanted slavery. This law worked horribly and caused a significant amount of violence in Kansas.

The law became controversial because citizens who did not want slavery argued that the election was rigged, as individuals came from Missouri to vote for slavery. These claims caused controversy between the people who wanted Kansas to be a free state and those who wanted it to be a slave state. This resulted in essentially a small civil war. This era in Kansas history became known as "Bleeding Kansas."

The price of oil and inflation are connected in a cause and effect relationship, that is, when the price of oil increases, inflation also increases in an economy. this is because, oil is a major input in the economy, that is, it is used for critical purposes such as fueling of vehicles for transportation, for running of industrial generators and machines, for heating homes, etc.for instance, if the price of oil increases in an economy, it will increase the cost of production for those using the oil in their production processes and they will automatically increase the cost of their products in order to offset the extra costs. this leads to general increase in the prices of products in the market and result in inflation.
