Given that the World population changed little between this time, we can gather than the birth and death rates were similar, since they seem to cancel each other out from 1200-1400. To clarify, think of this. If you add something to a total (think births to population), but take away the same number (think deaths from population) you end up with the same total as before. Because of this, A is the correct answer choice (The birth rate and death rate were about equal).
In general, physical weathering from temperature changes is most common on the shorelines, because waves are able to take down rocks that have been weathers. They would be least noticeable inland, in desert areas with little forestation.
