Explain how the war with Mexico started to change the United States, both geographically, social, and political.

The War(s) with Mexico changed a lot of things. It brought a lot to the table.

Politically:

As a nation we hadn't quite yet developed a true sense of patriotism and even though "we" were proud to be American we didn't have that "America, Fundip Yeah!" zeal quite yet. As this war started a lot of news influence helped develop a lot of that. It changed how the people saw Mexicans and it gave the incentive for us to go to war to "take back our land" and "stop the invasions."

Socially:

This war brought a lot of people together and made it quite a "unite against a common enemy" situation.

Geographically:

This war made a big difference in size. We acquired "California." I use that loosely because what was "California" then is now Cali, Nevada, and some of Arizona and Oregon. (Don't quote the Oregon part haha). We wanted this land because we found gold there. We, as Americans, Decided that we wanted "what was rightfully ours," and we would do what it took to get it. But really we just wanted gold.

If you want any clarification or anything of that sort, let me know! :) I hope I helped and if I did a brainliest would be awesome! :)

the american rail road was the most influential and useful transportation system developed in the 1800's with steam locomotives and in the very late 1800's and early 1900's diesel electric locomotives being used to transport goods and people around the newly expanded united states!

b. after i get up in the morning,

explanation:

after is a subordinating conjunction that introduces a time clause. time clauses are dependent clauses used to indicate when something happened.

the clause "after i get up in the morning" tells when the action in the main clause (drinking a cup of coffee) happens:

"after i get up in the morning, i drink a cup of coffee." it is the most logical choice of all.
