Answer:
German paper marks rapidly lost value between 1918 and 1923
Explanation:
Between the period 1918 ans 1923, the German economy crumbled rapidly and it had enormous inflation, resulting in large scale poverty in the country. This can be seen very well from the presented graph, as at 1918 one paper Mark was almost equivalent to one gold Mark. Then as the years pass by the paper Mark starts to lose on value, and by 1921 it is almost 1,000 paper Marks that were the equivalent of one golden Mark. From 1922 we have a sharp loss of value of the paper Mark continuing in the next 1923, with the end result being one billion paper Marks to be equivalent to one gold Mark.

of learning.
The correct answer is option D. "Companies replaced hand-operated brakes with air brakes on trains". The development of air brakes on trains was a significant improvement of railroad safety. Air brakes function much more faster than hand-operated brakes, because hand-operated brakes required that the brakemen turned the brakes in one car and jump to the next to set the brakes on, and so on.
