Final answer:
The statement that is NOT TRUE about immigration from 1970-1920 is that there was a later shift of immigrants coming mostly from Ireland and Germany to places like Italy and Poland. Immigration from southern and eastern Europe, not Ireland and Germany, dominated the latter part of the nineteenth century into the early twentieth century.
Step-by-step explanation:
The statement that is NOT TRUE about immigration from 1970-1920 is: At first, immigrants were coming mostly from Ireland & Germany, but it later shifted to coming from places like Italy & Poland (D). While immigration from Ireland and Germany was significant in the first half of the nineteenth century, the predominant wave of immigration in the latter nineteenth and early twentieth century chiefly included people from southern and eastern Europe, such as Italians and Eastern European Jews, rather than a shift from Ireland and Germany.
Most immigrants indeed settled in eastern cities, but some headed west for jobs in industries other than mining, such as agriculture (A). Second and third class passengers were subject to physical examinations at Ellis Island (B), and it's true that the majority of immigrants traveled in steerage, the lower parts of ships (C). The influx of immigrants, especially from Italy and Eastern Europe, profoundly shaped the American demographic landscape during this period.
