The statement that best describes an effect of migration is:
Mass migration can prompt negative political reactions to migration.
This is a common phenomenon in many countries where an influx of migrants may lead to concerns about resources, integration, and national identity, leading to political backlash or anti-immigrant sentiments.
The other statements have limitations:
- Economic benefits can be felt by both the receiving and sending countries.
- Social effects can exist in both the sending and receiving countries.
- While migration can lead to investments in education, this is not a universal effect and can vary significantly by context.
