in 1882, prussian doctor robert koch discovered the bacterium that causes tuberculosis,
an infectious disease that mainly affects the lungs. at the same time, doctors began to
understand that microscopic organisms, not dirty air, caused some diseases. as a result
of kochs work, it was understood that tuberculosis was contagious. health officials
wanted to stop the disease from spreading, so public health campaigns were launched in
the united states and europe. oddly, many campaigns warned that womens fashions
could spread the disease. at the time, long skirts that trailed along the ground were in
fashion. it was believed that these floor - length skirts picked up germs on dirty streets
and brought them into the home. consequently, skirt hemlines were raised several inches
at the beginning of the 1900s, ushering in a new fashion trend.

Explanation:

• When Koch isolated the tuberculosis bacterium, it led to the understanding that microscopic organisms caused diseases. This, in turn, made it clear that tuberculosis was contagious (so "Koch isolated the tuberculosis bacterium" causes "Tuberculosis was determined to be contagious").
• Since doctors wanted to prevent the spread of tuberculosis (a contagious disease), public - health campaigns (including warnings) were launched in the US and Europe (so "Doctors wanted to prevent the spread of tuberculosis" causes "Public health warnings were issued in the United States and Europe").
• As people believed long skirts spread disease (by picking up germs), skirt hemlines were raised (so "People believed long skirts spread disease" causes "Skirts were shortened").

Answer:

• Koch isolated the tuberculosis bacterium → Tuberculosis was determined to be contagious.
• Doctors wanted to prevent the spread of tuberculosis → Public health warnings were issued in the United States and Europe.
• People believed long skirts spread disease → Skirts were shortened.
