Final answer:
Carlos's concerns about trade restrictions impacting his import business stem from political factors, as governmental actions are the main influence on changes in trade policies that might lead to increased costs and sourcing challenges.
option 2. Political factors is correct answer.
Step-by-step explanation:
The primary source of Carlos's concerns about his Mexican handmade craft import business in light of potential new trade restrictions by the government is political factors. The government's decision to limit imports from Mexico to increase employment within the United States is an example of how political decisions can directly impact international trade and the operations of businesses that rely on imported goods.
Implications of such trade restrictions include increased costs for importing products and potential difficulties in sourcing goods for Carlos's store. Changes in trade policies, such as the imposition of tariffs or quotas, are driven by the political climate and have a significant impact on businesses involved in international trade.
