In a well-written paragraph, explain how the governments of two different countries are similar and different. Use at least two of the following terms in your response: autocracy, oligarchy, democracy, unitary, federation, confederation, parliamentary.

In Germany, the power is with the people (=it's a democracy) which are represented by the members of the parliament: it's a representative democracy. It's also a federation of 16 states. 

Iran, on the other hand is a theocracy: a country ruled by the members of the clergy. It can also be named an oligarchy: the power is with a few members of the society.

freedom of speech is also protected by the 1 amendment.

explanation:

here is pretty much what the 1st amendment says:

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
