Answer: D. Only those who worked could get good health insurance was not a reason that most members of immigrant families had to get a job.
Explanation: D is the correct answer because health insurance was not a factor that influenced most members of immigrant families to get a job during the period of mass immigration to the United States. Most immigrants who came to America in the late 19th and early 20th centuries did so to escape poverty, persecution, and limited opportunities in their home countries. After spending all their savings to pay for passage to America, they often had no choice but to find work to survive.
