Answer:
BAC.
Explanation:
The cosmological model of the Big Bang theory helps to locate the beginning stages of the formation of universe. The model is based on the laws of Edwin Hubble and Georges Lemaître.
According to the Big Bang model, the correct order of the given events would be written in BAC chronology. As per the model, the first stage was taking place of the Big Bang, also known as the Planck era. The Big Bang took place at 10^ -43 seconds. The birth of stars and galaxies took place 300 million years after the Big Bang took place. After the formation of new stars, the gases begin to move together. In this rippling of these gaseous clouds, the sun forms the Milky Way Galaxy.
Therefore, the correct answer is BAC.

You can tell what key it is in by the starting note. Therefore, for example the first question is on "D", and it had a flat accidental. Therefore it is a Db (D flat). Now, we can use the circle of fifths
[first attachment]
to help find out where the sharps and flats fall, and since this is a major scale, the pattern is Wholestep Wholestep Halfstep Wholestep Wholestep Wholestep Halfstep (WWHWWWH).
Therefore the pattern is Dflat Eflat F Gflat Aflat Bflat C and Dflat again. You can write there as notes on the scale

You can do this for the rest of question 6.

Just choose a key signature from the circle of fifths (an easy one is G) and put that key signature on your staff. Secondly, choose a time signature. The easiest is 4/4. If you're in "G", start in key of "G" and make a simple tune. e.g
[third attachment, scroll right]
for the other tunes, just choose different time signatures and key signatures and switch up the tune.
Hope I helped and good luck!
The answer is B) pigments!!
