economic push factors in Europe resulting from crop failures

The theory explaining the Great Atlantic Migration involves a combination of economic push factors in Europe resulting from crop failures, environmental pull factors in the U.S. due to a desirable climate, economic pull factors in Europe due to industrial growth, and political push factors in Europe due to governmental instability.

To determine which option forms a theory explaining the Great Atlantic Migration, we need to evaluate each option's relevance to the migration phenomenon.

The Great Atlantic Migration refers to the mass movement of millions of Europeans to the United States in the late 19th and early 20th centuries. In order to understand this migration, several factors come into play, including economic, environmental, and political factors.

Option 1: Economic push factors in Europe resulting from crop failures
Crop failures can contribute to economic hardships and result in people seeking better opportunities elsewhere. This factor could have played a role in encouraging migration.

Option 2: Environmental pull factors in the U.S. due to desirable climate
A desirable climate could have been an attractive factor for migrants seeking better living conditions. This factor might have influenced the migration to some extent.

Option 3: Economic pull factors in Europe due to industrial growth
Industrial growth can create job opportunities and higher wages, attracting individuals seeking better economic prospects. This factor may have played a role in the migration.

Option 4: Political push factors in Europe due to governmental instability
Governmental instability can create uncertainties, making individuals seek stability and security in other countries. Political factors may have influenced migration decisions.

Based on these considerations, it is evident that multiple factors contribute to the explanation of the Great Atlantic Migration. It is difficult to pinpoint a single option as the sole explanation. Instead, a combination of economic push and pull factors, environmental pull factors, and political push factors likely contributed to this migration phenomenon.
