2. [4pt] Match the type of distance measurement with the objects whose distance

Question

2. [4pt]
Match the type of distance measurement with the objects
whose distance can be measured using it (If the first corresponds to B, and the next 5 to C, enter BCCCCC):

1) nearby galaxies A. parallax
2) quasars B. type I supernovae
3) nearby stars C. radar
4) galaxy clusters D. redshift (Hubble Law)
5) stars in our galaxy E. spectroscopic parallax
6) the Sun F. variable stars

5. [4pt]
According to the Big Bang Theory, order from earliest to latest, the sequence of events that are thought to have taken place at the beginning of the Universe. If statement A is first, B is second, etc. then enter ABCDEF.

A) Inflation occurs.
B) Hydrogen and Helium are synthesized.
C) Most carbon and oxygen in the Universe is produced.
D) Symmetry of the four forces is broken and gravity becomes a separate force.
E) The universe becomes transparent releaseing the photons of the Cosmic Microwave Background.
F) Protons and anti-protons form.

Please be 100% positive this is my third time posting becuse the other two were wrong! Thanks!

5) stars in our galaxy E. spectroscopic parallax

6) the Sun F. variable stars

Answer)

1) nearby galaxies B. type I supernovae

2) quasars F. variable stars

3) nearby stars A. parallax

4) galaxy clusters D. redshift (Hubble Law)

5) stars in our galaxy E. spectroscopic parallax

6) the Sun C. radar

So the answer is : BFADEC
