The statement that most accurately describes an effect of migration is: "Mass migration can prompt negative political reactions to migration."
Mass migration often leads to political debates and reactions in receiving countries, which can include anti-immigrant sentiments, changes in immigration policy, and the rise of nationalism. The other statements are either incorrect or overly simplistic regarding the effects of migration.
For instance:
- Economic benefits from migration can be felt by both the sending and receiving countries. Sending countries may benefit from remittances.
- Social effects can occur in both the sending and receiving countries, including cultural exchange, demographic changes, and potential social tensions.
- Mass migration may lead to increased investment in education in both sending and receiving countries, not just in one or the other.
