b. danger
c. risk of human error
d. negative media coverage e. lack of qualified astronauts

Respuesta :

From the choices, I believe that the answer is letter B. danger. Even if we train people very well, we can never tell what is in the space that is not our habitat in the first place. It is dangerous for the human especially if faced with unexpected and challenging circumstances.
