Miners, farmers, scientist, merchant Seamen, railway and dock workers, and school teachers.
The answer is B, Degradation
I had this question in my quiz and got it right.
Life would have been different without the locomotive because you could not travel to far places quickly and efficiently. To get there you might have to walk, but you could be kidnapped, robbed, or catch a sickness. With the locomotive, you could get to places such as California safer and quicker.
First one for sure
im guessing third one too
plz wait for another person to answer the rest but im pretty sure its only those two
hope this helps
