Clear cutting large areas of trees at a time:

a: increases the amount of rain available to the soil
b: reduces the amount of rain since moisture is no longer available for evaporation in the canopy
c: has no effect on the amount of rainfall in this area
d: increases the amount of thunderstorms in this area

The answer would be c because cutting down a bunch of trees would effect wildlife but it would not effect the amount of rain in the area. The clouds will not decide to rain less when trees are cut down because that is not how nature works

iii. and iv. only is the right answer

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]
