a. emigrate
b. more
Explanation:
Immigration attractiveness is a factor that draws immigrants to a foreign country. A country becomes more attractive when the economic prospects are brighter than at the home-country. The degree of immigration law enforcement also helps to either attract or deter potential migrants. In recent years, wars and misgovernment have propelled millions to move boundaries. At the same time, countries are imposing migration restrictions by imposing and implementing strict laws.
