Main idea: It is estimated that over twenty million pounds of candy corn are sold in the US each
year. Brach's, the top manufacturer, sells enough candy corn to circle the earth 4.25 times
if each piece were laid end to end. That's a lot of candy corn, but that's nothing compared
to the production of Tootsie Rolls. Over 64 million Tootsie Rolls are produced every day!
But even Tootsie Rolls have got nothing on the candy industry's staple product:
chocolate. Confectioners manufacture over twenty billion pounds of chocolate in the
United States each year. Now that's a mouthful!
What is an appropriate title?
Summarize this paragraph in one sentence. Be specific and clearly explain the main idea.

3one of the biggest impacts a building has on earth is the energy it uses. currently, most of the world’s energy comes from burning fossil fuels. these fuels are dirty and when they are burned they pollute the air and water. one way to burn fewer fossil fuels is to reduce the amount of electricity a building has to use. passive solar heating, which uses heat from the sun, reduces the amount of fossil fuel used to heat buildings. passive solar heating requires a south-facing wall made of glass. when sunlight shines through the wall, it is collected and used to warm the building. another way green buildings reduce their electricity use is to install other energy sources. for example, some green buildings use panels that turn energy from the sun into useable electricity. which is the best summary of paragraph 3? a) fossil fuels are dirty and pollute the air and water. most of the world's energy comes from these fuels. b) the biggest problem of buildings is that they use fuel that is dirty for heating. they need to do something to be more energy efficient. c) panels that turn energy from the sun into electricity and passive solar heating can stop the burning of fossil fuels which pollute air and water. d) since fossil fuels are dirty and pollute the air and water, other technologies that pollute less and produce energy have been developed like solar energy and green buildings.
