PARAGRAPH 7.4
Keep Physical Education
There are several reasons why I do not think that schools
should reduce the time for physical education. First, I think that it
is unfair to make students sit in class all day. They need a chance
to take a break and move around. Second, exercise brings oxygen
to our brains. This can help students focus better on their lessons
and learn more. Last, I believe that physical education classes
teach students healthy habits. This is important because students
will miss fewer classes if they are healthy. I truly feel that reducing
the time for physical education in schools is not a good idea.

An Important Invention
The light bulb is one of the most important inventions of
all time. In the past, people used candles to see at night. This
light was very weak and difficult to see with. However, now the
light bulb lets us see things easily in the dark. This invention
also helps us to do more work in one day. Before the light
bulb, most work ended at sunset. Now people can continue to
work outdoors or in their offices after the sun goes down. In
addition, people can enjoy live entertainment when it is dark.
For example, sports fans watch games at night on lighted fields,
and music lovers listen to concerts in lighted stadiums. Without
the invention of the light bulb, our lives would be very different.

PARAGRAPH 8.4
Earthquakes Caused by Humans
1 Several types of human activity can set off earthquakes.
2 First, mining can cause earthquakes. 3 When we remove dirt
from the ground to build mines, the earth can become weak.
4 If it collapses, an earthquake can happen. 5 Next, humans can
cause earthquakes by building dams. 6 The weight of so much
water in one place can set off an earthquake. 7 In addition,
earthquakes can happen because fracking is used to get oil or
gas from the ground. 8 When the water that comes up with the
oil or natural gas is put back into the ground, it can cause an
earthquake. 9 If we continue to dig mines, build dams, and use
fracking, we will have more and more earthquakes.

PARAGRAPH 8.6
The Island of the Colorblind
There is something unusual about Pingelap Atoll, a small
island in the South Pacific. About 10 percent of its population
is colorblind. This means they cannot see most or all colors.
When a terrible storm hit the island in 1775, it killed most of the
islanders. Because the population was so small, the gene for
colorblindness passed to a lot of people over the next several
hundred years. Their condition is known as achromatopsia.
Some of the people on Pingelap who have achromatopsia are
able to see colors like red and blue, but others only see black
and white. People’s understanding of color is certainly different
on Pingelap Atoll.
