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).

Answer:

zenith distance = 39 degree

Explanation:

given data

declination of star = -13.00º

latitude = 26.00º N

to find out

distance in degrees between the star and zenith

solution

we know the formula that is

latitude = star declination+ its zenith distance ....................1

and

zenith distance = latitude - star declination

zenith distance = 26 - ( -13 )

zenith distance = 26 + 13

zenith distance = 39 degree
