Which of the following best states a way that “old” immigrants differed from “new” immigrants in the 1800s?

old immigrants were protestants and jews, while new immigrants were catholics and jews.

old immigrants settled among the native population, while new immigrants formed their own neighborhoods.

old immigrants were welcomed by the native population, while new immigrants were met with hostility.

old immigrants often had property and skills, while new immigrants tended to be poor, unskilled workers.

I believe the answer is: Old immigrants often had property and skills, while new immigrants tended to be poor, unskilled workers.

The old immigrants came into united states when it's still consist of mostly empty land, so people who dare to come here were tend to be highly skilled individual who understand how to operate businesses and they help in building United States to the super power that it is today

The new immigrants came into united states when it already rich and has one of the highest standard of living in united states. Even though this not applicable to all immigrants, it is a fact that rich nations often attract many unskilled workers since the standard of living of 'poor' people in united states can be higher than the standard of living of 'middle class' people in non-developed nation.

explanation:

there are two statements that are incorrect.

1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.

2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.

the 4th choice is definitely so wrong that is likely the single answer of this question

worcester v. georgia, legal case in which the u.s. supreme court on march 3, 1832, held (5–1) that the states did not have the right to impose regulations on native american land. andrew jackson refused to enforce the ruling, the decision form the basis for most subsequent indian law in the united states.
