like the common market, a(n) ________ involves the free flow of products and factors of production between members and the adoption of a common external trade policy.\n\n a. customs union\n b. currency union\n c. global union\n d. free trade area\n e. economic union
Answer
Brief Explanations:
An economic union allows for the free - flow of products and factors of production among members and has a common external trade policy. A customs union only has a common external trade policy without full factor mobility. A currency union focuses on a common currency. There is no such thing as a global union in this context. A free - trade area only has free trade of goods among members without a common external trade policy.
Answer:
e. economic union
