Answer the questions (12 - 13) according to the passage below.
During Pasteur's time, people thought that the bacteria just appeared out of nowhere. Pasteur ran experiments to see if this was true and he proved that germs (i.e. bacteria) were living things that came from other living things.
Pasteur used his knowledge of germs to
investigate how beverages such as wine
and milk were spoiled by microbes such
as bacteria. He found that heating up the
liquids would kill most of the microbes and
allow the beverages to last longer and be
safer to drink. This process became known
as pasteurization and is still done on many
foods such as milk, vinegar, wines, cheese,
and juices. RNEKT
