A. John Dalton would make the following statement: "There must be a positive charge located in a tiny area at the center of an atom."
First question: D- people who were living in America at the time, didn't want other people to come in and "steal their jobs". To me, nativism (at the time) was a pretty stupid thing, considering how many of the people who didn't want anyone else coming into the country, were immigrants themselves.
Second question: D is the closest answer, seeing as Roosevelt wanted to improve relations with Central and South America.
Hope this helps!
This can be something as bizarre as an Alien from another Galaxy, or whether or not you should get paid. This question is very general and usually should be answered where the opposition or question is not in America or American, as that will ruin the unite everyone.
