▶ Your Answer :
Both the reading passage and the lecture
deal with brain scan lie detector. In the writing, there is ample support for the author’s
claim. However, the
professor in the listening gives several reasons as a rebuttal against the
author’s point.
To begin with, the lecturer argues that
Brain scan lie detector is not better than former one. This is because when people
want to conceal informations such as sensitive or embarrassing topic, the brain
tend to use some part which is same part as lying. Therefore, it is not give
precise information. This casts doubt on the reading passage’s claim that new
lie detector is more accurate than former one since it scan subject’s brain.
On top of that, the speaker maintains that an
objective manner of new lie detector is plainly false. This is because people
tend to use different function of brain slightly each other, so it does not have primary criteria, and it cannot elicits outcome consistently
as well. As a result, new machine also need expert’s
analysis. This counters the author’s suggestion that brain scan machine
interpret in an objective manner since it scan actual image of the specific
parts of the brain that are involved in lying.
Lastly, the speaker contends that it is easy for
subject to cheat even if brain lie scanner used. This is because when people
think complex topic, the brain become active state, which is same state when
people lie. Moreover, if subject practice untrue story in advance, it will turn
out honest. This refutes the writer’s point that brain lie scanner could make
difficult to fool to subject.
