Answer 1

All of the above are correct

Step-by-step explanation:

Faster mail delivery because people were able to transport news quicker

Mass transportation because more people were able to use the railroads at a time to get from one place to another, instead of using other modes of transport like horses

Changes to industry because people(workers) also used the railroad to transport supplies and other things without having to carry them themselves, which made industrialization happen faster
