VI. Read the text then answer true or false
People use many sources of energy. Ancient people used only their arms, hands, and
simple tools until they discovered fire. Later, people learned to use the energy of the wind to
sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth
centuries, people began to use machines. The first machines used steam. They burned coal
to heat water. The hot water turned into steam, and the steam engine did the work. Later,
people began to use the gasoline engine, and today people are using nuclear energy.
