Question

Which factor has not contributed to the growth of international trade?
-the spread of reliable communications
-a change in the tariffs charged on many foods
- reduction of shipping costs
-favorable changes in government policies

Answer 1

A wide range of political, economic, and practical factors can affect the growth of international trade. Many nations have a variety of legal regulations to which businesses must conform before engaging in trade internationally, and some nations even have economic policies that strongly discourage it in favor of a more internally-focused economy.
Communication is also important, as technology such as the Internet now allows for nearly-instantaneous communication around the world, thereby allowing businesses to market their products and services globally with relative ease.
The economic condition and economic policies of a given nation are also important factors that affect the growth of international trade.
Rapid global communication by telephone and over the Internet is a major factor affecting international trade as well.
So, the incorrect statement is "the spread of reliable communications".
