Answer 2

Answer

Second Scenario

Explanation

You are given the formula

Population growth = (birth rate + immigration) - (death rate + emigration)

1st scenario

Emigration = 0
Death rate = 14
Birth rate = 14
Immigration = 14

Therefore pop growth = (14 + 14) - (14 + 0) = 14

This is positive pop growth

2nd Scenario

Emigration = 40
Death rate = 0
Birth rate = 10
Immigration = 28

Pop growth = (10 + 28) - (40 + 0) = -2

This is negative population growth therefore it’s the second scenario
