The railroad industry.
Explanation:
George Westinghouse was an American innovator that had huge impact on the development of the railroad industry. His most notable innovation that improved the railroad industry was the railway air break. This was extremely important, especially in the 19th century, as the trains often found themselves in a situation where a highly efficient break is needed urgently, but they didn't had such at disposal.
Many accidents have happened because of the inefficient breaks, so when Westinghouse came up with his railway air break it was seen as a savior invention which will help the railroad industry a lot when it comes to accidents, repairs, or constantly making new trains. Westinghouse put in all of his effort and finances into patenting and promoting this innovation, as well as the others he had, and it paid off for him over time.

Answer:
The correct answer is B, <em>Republicans in Congress did not trust white southerners to adopt reforms giving rights to freed slaves</em>.
Explanation:
During this period Congress passed laws in order to reintegrate the country and to enforce what had been fought for in the Civil War, that is, the end of slavery.
After seeing that white southerners were getting their lands back and they were reorganizing their government without making it very differently from before the war, Republicans in Congress decided to enforce the Civil Rights Bill.
For the Bill to be put into practice in the south, Congress divided the South into military districts whose governments would be under martial law until black people's civil liberties were ensured. That meant that black people should be present in the government to ensure African-Americans wouldn't have basic rights denied.
