Question

backs on the real challenges that face us here and now. even if we can, with the devotion of enough resources, withstand the harsh conditions in transit and the problems of survival on an unforgiving planet, it doesnt mean we should make the journey. what is the authors main claim or argument? we need to develop better technology before going to mars. we must be humble and cautious if we choose to send people to mars. we should not send humans to mars because the costs and risks are too great. human exploration of mars is inevitable, so we must develop a safe way to do it.

Explanation:

The text states that even if we can withstand the harsh conditions and survival problems on Mars (by devoting enough resources), it doesn't mean we should make the journey. This implies a consideration of costs (resources) and risks (harsh conditions, survival problems) and a hesitation or opposition to sending humans.

Answer:

We should not send humans to Mars because the costs and risks are too great.
