D

Explanation:

During the Progressive Era, new immigration from southern and eastern Europe reached its peak. Most of these migrants were non English speakers from countries like Russia and Poland. As a result of this migration, cities became overly crowded as most migrants chose to live in cities. This created a huge problem as existing infrastructures could not cater from just huge influx.

even though you have attached neither the chart nor the generalizations, i have located them online. the right answer is d, since they are asking you about a generalization. you can only infer from the chart that between 2008 and 2009 the number of employed workers decreased significantly (from over 115 millions to 107 millions approximately), which signals some type of economic crisis.
