<span>C) Herding animals
The asals are ideal for pastoralist activities. The rotational nature that semi arid areas demand is only ideal with herding activities. In as much as the ecosystem is balanced, the areas are viable options for herdsmen.

If we know that 180-5=128 that means that that equation must be equal to 128.
(2^3x+1)=128
By putting 128 into exponential form with a base of 2 you get 2^7:
(2^3x+1)=2^7
Since these have the same bases we can set the exponents equal to 7. This will give us an exponent of 3x+1=7. By Subtracting across and dividing by 3 you get:
3x=6 to 3/3x = 6/2
This gives us a final answer of:
x=2
