▶ Your Answer :
In the lecture, the speaker contends that problems posed by a manned mission to Mars can be overcomed. This contradicts the reading passage's assertion that a manned Mars expedition would causes serious problems.
To begin with, the lecturer claims that Martian dust can be controlled through sound technique. This is due to the fact that by causing sound waves, dust can be blown away, while not harming the spaceship and astronauts. This challenges the reading passage's point that Martian dust causes insurmountable threat to the astronauts and spaceship.
Second, the speaker asserts that psychiatric problems caused by a manned Mars expedition can be manageable. To be specific, astronauts actually learns techniques to deal with isolation during a Mars mission before their expedition. Morever, counselling is avaialable through computer programs, including recorded video therapies. This rebuffs the reading passage's claim that lengthy trip to Mars causes psychological problems.
Last, the lecturer says that the financial burden of a manned mission to Mars is actually prevented from occurring. The reason is, international space station deals with it by partnership between various countries. Also, since manned Mars expedition leads to technological development, it is worthwile in the long term. This casts doubt on the reading passage's point that it would be quite burden for a country to bear the financial burden of a manned Mars expedition. |
