The authors would be most likely to agree with which one of the following statements?
Correct answer:
A. Expected financial gains alone may not be a reliable indicator of the likelihood that na individual will migrate.
Support: In the third paragraph, the authors lay out the sources that hinder people from migrating. These three reasons outlined are a mixture of difficulties and cost. Difficulties include uncertainty of the market, the third discusses a change in culture and language. The second one directly relates to cost.
In the fourth paragraph the economists address their theory, which is how previous migrants lessened some of these burdens (they gave information, and they helped them adapt to local culture. They also helped ease the cost. But this all suggests that the authors believe there are other factors aside from financial gains alone that will dictate whether an individual will migrate.

B. This answer is tempting. The passage begins with this background information. However the authors are actually focused on explaining the continuation of the migration.
C. The authors slightly reference other migration movements (when they discuss research and patterns) but we definitely don't have support for the "most" found in this answer. This also does draw comparisons to the ones that it references. Eliminate.
D. Most? Again, we have no idea about the percent of large-scale migrations that fall into this pattern. Eliminate.
E. There's nothing to suggest that this was the first or close to first time this happened. Maybe in the US, but this is way too strong and unsupported.
