What is a primary? who holds the first one?

Primary,  are  chief importance; principal.  "the government's primary aim is to see significant reductions in unemployment" who hold  it is the first binding event, in which a candidate can secure convention delegates, is traditionally the Iowa caucus, usually held in late January or early February of the presidential election year.  that what I read online somewhere.

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.
