▶ Your Answer :
According
to the reading, the reading passage claims that there are remarkable several
advantages of living roof. In the lecture, however, the professor argues that
disadvantages of living roof outdo the advantages. The professor has several
reasons to support his own opinion.
First of all, the professor says that the
living roofs couldn’t function as park. This is because the living roofs are in
accessible. In other words, people should get to top of building when they want
to see the living roofs because of the location where the living roofs are. This
denies the reading passage’s claim that living roof has potential to replace
public parks.
Secondly, the reading passage describes a
method of preventing pollution by living roofs. However the professor doubts on
process of living roof preventing pollution. This is because roots can penetrate
protective material laid down beneath living roof, so that rains can be absorbed
inside of concrete, this causes to make water pollution. This assertion negates
the reading passage’s insistence that living roofs help prevent water pollution.
Lastly, it is true that living roofs help
moderate temperature of a building, keep urban space warmer. So, they reduce
cost for energy. However, the professor claims that there is a problem to build
the living roofs. The problem is expensive cost of installation and
maintenance. Therefore, the professor rebut the reading passage’s claims that installation
of living roofs can be helpful for urban. |
