▶ Your Answer :
In the given set
of materials, the reading passage and the lecture deal with compact fluorescent
lamps to debate whether it can solve the energy efficiency problem. The reading
passage is providing three pieces of evidence to prove its point, whereas the
lecturer argues against it by providing three compelling rebuttals.
The reading
passage asserts the idea that the price of a CFL is way too high, when compared
the benefits it provides. This high price prevents consumers from purchasing it.
From the perspective of the average consumer, it is a waste. The professor
casts about because CFLs’s life span is longer than an incandescent lamp.
The reading claims
that CFLs contain mercury, which causes environmental problem. Moreover, the
disposal of CFLs has become a problem to be solved, since each state has different
rules for their disposal. While people dispose CFLs as universal waste, the
recycling of the lamps should be urged. The professor refutes the idea because
If it used to keep them unbroken, It not emit mercury.
The reading points
out that a major problem of CFLs is related to health. CLFs emit the
ultraviolet rays that put health in risk and people with sensitive skin, or
rare skin conditions, may even develop skin cancer. The professor challenges
the idea because it is harmful when people are only exposed by CFLs long time
and closely.
