How easy would it be for future astronauts to psychologically adapt to living on Mars?
 
  A) fairly easy because the Martian day is only about 40 minutes longer than the terrestrial day
  B) extremely easy because the Martian day is exactly the same length as the terrestrial day
  C) very difficult because the Martian day is much longer than the terrestrial day
  D) very difficult because the Martian day is much shorter than the terrestrial day

Question 2

Process of Science: In the discovery of quasars, the radio source 3C273 was found to have strong emission lines at wavelengths that did not correspond to any known element on Earth.
 
  Suppose a scientist postulated that they had discovered a new element that only existed in these powerful radio sources. How would you test this?
