Trade protection refers to government policies that restrict or regulate international trade, usually in the form of tariffs, quotas, and subsidies, in order to protect domestic industries from foreign competition. Free trade, on the other hand, is a policy that allows unrestricted trade between countries, without tariffs or other trade barriers.

a) It is not true that there are no arguments in support of trade protection. Many valid arguments exist, such as protecting domestic industries and jobs or national security concerns. However, whether those arguments outweigh the benefits of free trade is subjective. b) This statement is subjective and cannot be considered universally true. Some people may believe that the arguments for trade protection are more valid, while others may believe in the benefits of free trade. c) The United States has not always fully supported free trade since the early 20th century. There have been periods of protectionism and free trade policies that have shifted over time, depending on economic conditions and political ideologies. d) It is true that much of what is imported, particularly from developing countries, has been produced under poor working conditions, often referred to as "sweatshop labor." This issue is associated with global trade and raises ethical concerns.
