▶ Your Answer :
Both the reading and the lecturer talk about color blindness.
According to the reading passage, the writer states that color blindness cannot
recognize color at all, so they are called as monochromatic.
However, the lecturer casts doubt on the writer’s point by
asserting that the validity of the reasons described in the reading is open to
question.
First of all, the reading state that color blindness is regarded
as genetic defect or injury in that it has problem in the eye’s retinal cone
that take in color and convey information to the optic nerve. Also, it is highly
possible to affect more men because the ability to perceive color is carried on
the x chromosome. However, the lecturer asserts that this notion is false. This
is because colorblindness is caused by evolutionary purpose so that it cannot marked
disability. To be specific, the 8% of male and 0.5% of females can called color
blindness.
On top of that, the writer contends that colorblind person has
difficulty doing for many position such as Army and Marin copes since these
jobs require the ability to distinguish reds and green. Thus, the colorblind
person cannot fulfill their duties on the battlefield. However, the speaker casts
skepticism this claim by asserting that those people have advantages for specific
jobs since they can easily perceive objects in the nighttime, thus they have benefit
in battle field.
Lastly, the writer goes to explain that blindness has a negative
impact on their daily life since they cannot read traffic signal and warning
lights. In addition, they had difficulty for watching television or viewing
art. In contrast, the lecturer asserts that they have no difficulty from understanding
signal for traffic because the signal has same pattern. Also, there are many
famous artistes with blindness. They used etching and monochrome in their works.
Given this, it is not make sense that color blind person cannot enjoy arts.
