Question 2

Which of the following is not a major reason why astronomers would like an observatory on the far side of the Moon?

  B) Radio astronomy would be advantageous on the Moon because human radio transmissions are less likely to cause interference, especially on the far side of the Moon.
  C) It would be possible to put telescopes for ultraviolet and X-ray astronomy on the surface, unlike the case on the surface of the Earth.
  D) Telescopes on the Moon could observe stars even when it is daytime on the Moon.
