Question

A country is least likely to use __________ to limit the movement of people into its borders. A. immigration quotas B. passports and visas C. sanctions and embargoes D. physical barriers

Answer 1

Most likely it would be c

Answer 2

The correct answer is B.

Nowadays, countries mostly require documents and valid IDs so that people from abroad are allowed inside their borders, rather than building physical barriers or establishing quotas to limit the number of people that are able to enter from each country of origin. These latter mechanisms are less frequent but not totally erradicated anyway.

On the other hand, sanctions and embargos are used to limit trade and products from foreign country, not people movements.
