Reading the passage
The authors connect the expected benefit of moving with the difficulty of making the move. Higher earnings matter, but so do uncertainty, travel costs, and getting established. Earlier migrants can change those obstacles even when the income advantage is shrinking.
What we’re looking for
Look for a conclusion supported by that relationship. We do not need identical wording, but we do need evidence for the claim’s scope.
Working the answers
- ACorrect
Expected financial gains alone leave out the costs and difficulties that can make moving attractive or unattractive. Two people facing a similar earnings opportunity could face different obstacles if one has a helpful network already in the destination. That fits the authors’ explanation of why migration could continue while the income gap narrowed.
- B
Earlier nineteenth-century migration is mentioned, but the authors do not say we must first explain its causes to understand the Great Migration. Mentioning an earlier event does not make it a required starting point.
- C
No comparison with most other known migration movements establishes that the Great Migration had unusually different broad patterns.
- D
The authors do not establish what adequately explains most large-scale migrations. Their central example also shows why a lower-income-to-higher-income description can leave an important question unanswered.
- E
Nothing establishes when large-scale migration generally began. The early-twentieth-century date belongs to this particular Great Migration, not to large movements of people throughout history.
