Because the more people a state has, the more power it has (in relationship to all the other states). So, since it has a big population, it needs more representatives to represent how many people there are. idk if this helps :/ sorry
Idea of the supremacy of the state over the individual
Christianity is a monotheistic religion that originated from Jesus who founded it. Judaism is the jewish religion made first by Abraham , then the newest of the 3 biggest religions is Islam founded by Muhammad
Please note all 3 religions worship the same god, they just have different holy texts, and views on gods prophets.
