▶ Your Answer :
In
the reading passage, there is ample support for the author’s claim that a manned
mission to Mars has some insurmountable problems. However, the professor gives
several reasons as a rebuttal to the author’s point.
First, the professor insists that the dust
issues can be controlled by sound techniques. He says sound waves can dislodge
the tiny dust particles off the surface of the spacecraft. Then, the dust can
be removed with a blast of air. This casts doubt the reading passage’s claim
that the dust in Mars can cause a serious threat to the spaceship and
astronauts.
Second, the professor contends that the
psychological problem of the astronauts is manageable. He mentioned that the
astronauts receive extensive training to cope with a prolonged periods of
isolation from family and friends. In addition, the counseling will also be
available using computer program which dispense advice and guidance for their
mental health. This counters the reading passage’s assertion that the mental
issues during the expedition are an additional obstacle to overcome.
Lastly, the professor argues that the cost of
a manned Mars expedition would not prevent it from happening. If several
nations pour their resources, they can cover the expenses. Moreover, even if
they do not receive benefit immediately from the expedition, there will be many
technological advances which is an advantage to the participating countries. This
refutes the reading passage’s suggestion that a manned mission to Mars is difficult
due to the financial burden.
