question # 11
multiple choice
which statement best describes how problem solving can lead to important inventions?
in different areas, during the same time period, two versions of the thermometer were invented
the stethoscope was invented by a french doctor who was embarrassed to put his head on womens chests to listen to their lungs
typhus was less common in hospitals when patients were bathed and provided clean clothes and linens
the tourniquet is used during amputations to cut the blood supply to the injured limb

Explanation:

To determine the correct answer, we analyze each option:

• The first option describes simultaneous invention of thermometers but doesn't link it to problem - solving leading to invention.
• The second option: The French doctor faced a problem (embarrassment to put his head on women’s chests to listen to lungs) and solved it by inventing the stethoscope. This clearly shows how problem - solving led to an important invention.
• The third option is about reducing typhus in hospitals through hygiene, not about invention via problem - solving.
• The fourth option is just a description of how a tourniquet is used, not about how problem - solving led to its invention.

Answer:

The stethoscope was invented by a French doctor who was embarrassed to put his head on women’s chests to listen to their lungs
