A shift in the hydrogen absorption spectrum of a galaxy provides evidence for all these EXCEPT temperature of the galaxy.

The other options — motion of the galaxy, expansion of the universe, and composition of the universe — can be inferred from shifts in the spectral lines due to the Doppler effect and redshift phenomena. However, temperature is not directly indicated by the absorption spectrum shift.
