The answer to that question is A
From 1860 to 1895, the United States experienced advances in technology, the industrial revolution and the Mexican-American war.
It can't be the Spanish American war because that didn't happen until some years later. It can't be an agrarian revolution because this is during the INDUSTRIAL Revolution and education at the time wasn't prioritized as much as it is today.
b.Johnson
Soon after the death of Lincoln, the war ended in 1865, as Andrew Johnson took the lead of the country trying to conciliate with the South. This caused a movement of people to the South, where within a year, they regained the power they had previously lost with the war. Naturally, the term carpetbagger is peyoraitve,and it was referred to Johnson and his Republican companions seen as opportunists. They plan was to be elected after the civil war came to an end. They sought approval from the South, where they were rather unpopular. The word is still sometimes in use in the United States referring to candidates for elections presented by their political parties in electoral areas with few or non-existent popularity.
