Question
One of the greatest lesson being learned from modern astronomy is that:

B: The chemistry, geology, and phsyics on Earth are unique to our planet, and the behavior of matter anywhere else appears to be significantly different from that on earth
C: Earth is at the center of a very massive black hole, and all the observed cosmological effects such as redshift and cosmic background radiation and even the evolution of life are a consequence of the unique position earth occupies
D: Earth occupies a unique position in the universe, and nowhere else are conditions equivalent to those in the solar system likely to be found
Explanation / Answer
The answer is A
The position and circumstances of the Earth in the univers are quite ordinary and certainly not of the unique type. Because many galaxies, like thousands are present in the universe and life may exist anywhere like that of the Earth.
