During the day, the Sun is too bright for us to see where it is located with respect to the constellations, but we can use our observations of stars at night to figure this out. Based on the way stars shift position over the course of a year, your knowledge of how the time of day is defined, and the fact that the same constellations are seen at the same place in the sky at the same time of night on a given day of the year, which of the following is most likely correct?
A. The Sun appears to move across the constellations over the course of a year, ending where it started with respect to the background stars by the end of that period. B. The Sun appears to move across the constellations over the course of a 24-hour period, ending where it started with respect to the background stars by the end of that period. C. The Sun always appears to be in front of the same constellation. D. The Sun's apparent location with respect to the constellations is random and cannot be predicted.
Why might inflation have occurred at the end of the GUT era?
A) Gravity was an extremely weak force at this period in time. B) Large amounts of matter and antimatter annihilated at this time. C) There wasn't enough matter present to slow down the expansion at that time. D) The universe was too small and needed to grow quickly. E) An enormous amount of energy was released when the strong force froze out from the GUT force.
