Question

which is not standing in the way of astronomers getting a good view of distant stars?
a. light gets distorted by gas and dust as it goes through the atmosphere.
b. some stars are too far away for our telescopes to see.
c. there is a lot of light pollution on earth.
d. redshift makes stars difficult to see.

Explanation:

A - Atmospheric distortion affects star - viewing. B - Distance limits telescope visibility. C - Light pollution on Earth hinders stargazing. Redshift is a phenomenon related to the motion and expansion of the universe, not an immediate obstacle to simply "getting a good view" in the sense of direct visual or instrumental obstruction like the others.

Answer:

D. Redshift makes stars difficult to see.
