Nationalist wanted the same concepts uniting the citizens overall. Everyone generally unites as a whole against a common enemy. However, there were some states that wanted independence to make their own decisions.

Explanation:

Well it united America in the industrial field somewhat.

And it divided certain ethnic backgrounds.

Explanation:

There was more women entering the factories to aid in the war therefore giving headway to more unity in the workplace.

Division sprung up in the discrimination that many Germans faced during the time of the war. They lost jobs and were often spat upon both figuratively and literally.

crop rotation kepy different plants in the soil instead of once constintly. when switching out plants you have different nutrients being absorbed at different speeds and different roots growing differently therfore the spoil and water flow have to adapt and carry fresh nutrients to carry the constant changes that were going on in the soil.

a big wall across the mexican border so no drugs, terrorist, or illegal immigrants can come through : )
