First of all, a <em>supply curve</em> is a chart in Economy that shows us the relation between Price and Quantity of a certain good or service. Several factors may cause this curve to shift to the left or right, e.g.: An increase of customers' purchase power, the decrease of the need for a certain product by the population, and so on...
a. Resource prices rise is another example, and would cause the supply curve to shift to the left. As with it, the final price of the products that depend on this given resource for their production, would rise, hence causing their buyers to purchase fewer quantities of them.
b. If a quota is placed on a good, it would also cause this good's final price to rise, hence causing the consumers to buy less, hence shifting the curve to the left as well.
<em>Note: </em>Of course, these are assuming that the goods in question are <em>non-essential </em>goods. That is, people may choose to buy less of them. In case of essential goods (like toilet paper, or electric power for example), people would still consume it regardless of changes in price! And in that case, the curve would stay still, or even shift slightly to the right, upon a price rise.
The correct answer to this open question is the following.
Based on the Judicial Branch the court case that stands out to me the most is Brown v. the Board of Education of Topeka, Kansas.
For me, this is one of the most important cases in the history of the United States.
The case was decided on May 17, 1954. The Supreme Court decided that state laws in the US public school system that kept racial segregation were unconstitutional.
This was a major advancement in the country regarding the shameful subject of racism. After the US Supreme Court decision, racial segregation in public schools of America ended, at least in theory and by judicial mandate.
