Since the 1950s the countries of Western Europe have seen
Answer
heavy industry come to dominate the economy.
immigrant laborers leaving in large numbers because of few job opportunities.
people from countries in the European Union able to access bank accounts, mortgages, and professional licensing in all nations in the Union.
shipments of goods increasingly hampered by national tolls and tariffs.
a lack in uniformity of regulations.
The correct answer is: a lack in uniformity of regulations.
To arrive at this answer, we need to analyze the given options and identify the one that fits the statement about the countries of Western Europe since the 1950s.
Option 1 states that heavy industry has come to dominate the economy. This does not address the statement about the countries of Western Europe, so it can be eliminated as an answer.
Option 2 states that immigrant laborers are leaving in large numbers due to few job opportunities. While this may be a concern in some cases, it does not directly relate to the dominance of heavy industry in the economy. Therefore, this option can also be eliminated.
Option 3 states that people from countries in the European Union have access to various banking and professional services across nations. While this may be true for citizens of the European Union, it does not directly address the dominance of heavy industry in the economy. Hence, this option can be eliminated as well.
Option 4 mentions an increase in national tolls and tariffs hampering shipments of goods. Although tolls and tariffs can affect trade, this option does not address the dominance of heavy industry in the economy, so it can be eliminated.
The final option, option 5, states a lack of uniformity in regulations. This option directly relates to the statement about heavy industry dominating the economy in Western Europe since the 1950s. The lack of uniform regulations can lead to challenges and disparities in various industries, including heavy industry.
Therefore, the correct answer is the fifth option: a lack in uniformity of regulations.
