Exercise 3
Correct the misused or missing articles and rewrite the paragraph:
Stars are large balls of spinning hot gas like our sun. The stars look tiny because they are
far away. Many of them are much larger than the sun. Did you know that a Milky Way galaxy
has between two hundred billion and four hundred billion stars in it? Scientists estimate
that there may be as many as five hundred billion galaxies in the entire universe! Just like
a human being, the star has a life cycle from birth to death, but its lifespan is billions of years long. The star is born in a cloud of cosmic gas and dust called a nebula. Our sun
was born in the nebula nearly five billion years ago. Photographs of the star-forming
nebulas are astonishing.

It is important to learn about finances. take, for instance, the old rule of saving ten percent of every paycheck. are most people aware that theyshould immediately take that percentage out of their paycheck and put it into savings? balancing your checkbook is another important element ofkeeping track of your money. buy a money tracking program and use it to manage your money. another important tip is to speak with a financialplanner and learn about stocks and bonds. come up with a savings plan that includes a 401k, stocks, and bonds. and start young. the longer youwait to save, the less compound interest you will accumulate. which is the best title for this paragraph?

Answer the question on the screen plzzz

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.
