Which of the following describes an effect of migration?

A. Economic benefits are only felt by the receiving country.
B. Mass migration can prompt negative political reactions to migration.
C. Mass migration causes an investment in education.
D. Social effects only exist in the sending country.

B. Mass migration can prompt negative political reactions to migration.

B. Mass migration can prompt negative political reactions to migration.

To determine which option describes an effect of migration, let's analyze each option:

A. Economic benefits are only felt by the receiving country.
This statement suggests that only the receiving country experiences economic benefits from migration. To determine if this is correct, you can consider the impact of migration on both the sending and receiving countries. Migration can actually lead to economic benefits for both the sending and receiving countries. For example, migrants often contribute to the labor force, fill job vacancies, and stimulate economic growth, which can have positive economic effects in both countries. Therefore, option A is not the correct answer.

B. Mass migration can prompt negative political reactions to migration.
This statement indicates that mass migration can lead to negative political reactions. Migration, especially when on a large scale, often leads to political debates and discussions. Concerns related to resources, cultural assimilation, employment, and national security can emerge, which may prompt negative political reactions. Consequently, option B can be seen as an accurate description of an effect of migration.

C. Mass migration causes an investment in education.
This statement suggests that mass migration results in an investment in education. While migration can lead to increased demand for education services in both sending and receiving countries, it does not necessarily cause an investment in education. Investments in education may occur due to various factors, including government policies or social considerations, rather than migration alone. Therefore, option C does not adequately describe a direct effect of migration.

D. Social effects only exist in the sending country.
This statement implies that social effects resulting from migration are present only in the sending country. However, migration can have social effects in both sending and receiving countries. These effects can include changes in demographics, cultural diversity, social integration, and the development of transnational communities. Therefore, option D is not a correct description of the effects of migration.

Based on the explanations above, the option that accurately describes an effect of migration is:
B. Mass migration can prompt negative political reactions to migration.
