Explanation:

both of these are correct but the answer is probably the first one.

The answer is:

A.(They were often poor and had few job skills)

The German, Irish and Italian immigrants who arrived in America during the 1800s often faced prejudice and mistrust. Many had to overcome language barriers. Others discovered that the challenges they had fled from, such as poverty or religious persecution, were to be encountered in America as well.
