Question

use the information from both passages to assist you in selecting by marking or circling the correct response that either answers the questions or completes the statement. 21. which statement best describes the relationship between population and migration? a) migration causes changes in population size. b) population and migration mean the same thing. c) migration only happens in cities. d) the population never changes because of migration.

Explanation:

Migration can involve people moving into (immigration) or out of (emigration) an area. When people immigrate to an area, the population of that area increases. When people emigrate from an area, the population of that area decreases. So, migration can cause changes in population size.
Option b is incorrect as population refers to the number of people in an area and migration is the movement of people. Option c is incorrect as migration can happen in rural areas too (e.g., rural - rural migration, rural - urban migration). Option d is incorrect as migration does cause population changes as explained above.

Answer:

A. Migration causes changes in population size.
