The creation of the european union has had all of the following effects except
a. increased trade between countries
b. increased immigration to member countries
c. increased migration between member countries
d. increased passport security at internal borders

The answer is D. Increased passport security at internal borders

The passport security will decreased instead ( only between member countries)

Option A is the main goal of forming a union between countries, so definitely not the answer

Option B & C is go hand in hand, if immigration in one countries increased it mean that the migration in other member countries is increased, so both of these options is not the answer

Low risk and moderate growth.
