Answer:
A
Step-by-step explanation:
Just finished taking the test. B and C are automatically not correct since old immigrants came more from western and eastern Europe, while new came from eastern and southern. D is also the first thing that should not be noticed as even a possible answer since the old wave of immigrants were the skilled workers and landowners, and the new immigrants were the unskilled workers and farmers. A did not sound very right to me (which is how I ended up here lol) but its the only logical answer. Hope this helps somewhat
