The area of Egypt and the Nile delta comprises one of the largest deltas in the world, extended along 240 kilometres of the Mediterranean shore. The delta starts a bit more to the North from the Egyptian capital, El Cairo.
It is an extremely rich agricultural area, which constituted the basis of the ancient civilizations established in the region. It has been exploited for thousand of years, due to the particularity that it used to flood anually, and the sediments left became high quality fertilizers for crops. Nowadays it has not flooded anymore since the construction of the Aswan Dam.
About 39 million people inhabit this area, and the largest city is Alexandria. Even though this region is economically quite important, it also registers most data-poor regions with respect to sea level rise
Some southerners threatened to secede over California's application for statehood during the middle of the 19th century because California would enter the US as a free state.
This means the state would not have slavery. Along with this, it would mean that there would be more representatives in Congress (aka the House of Representatives and the Senate) that are free states than slave states. This situation puts the southerners at risk, as the free states could make laws that would get rid of the institution of slavery. At this time, almost the entire south's economy depended on slavery.
I think the answer is A. I hope this helps out! ☺️
