The answer is A.) Deflation
I know jobs for one, over population maybe, and because they are worried that dangerous people could be entering into the country with intention to harm. (unless this is a "only 3 right answer" kind of thing)
Yes, the plate tectonics can also affect how volcanoes act.
To date, the majority of neandertal fossils have been found in Europe and western Asia.
There may have been little direct contact between neanderthals and modern humans over thousands of years. They might have contributed to the Neanderthals' impending extinction by preventing them from going back to the areas they liked best.
Around 40,000 years ago, all traces of Neanderthals vanished. The most recent Neanderthal fossils have been found at a few isolated locations in western Europe and the Near East, which was probably the last known location for this early human species.
