Hello there I hope my answer helps you
A character is a person or other being in a narrative
Besides stating that the correct answer is the first one (the church lost some of the influence it had during the height of the French Revolution), here is the explanation to better grasp the concept:
The Concordat of 1801, is an agreement signed on July 15th, between Napoleon, and the church representatives, in Rome and Paris.
This agreement defined the position of the Roman Catholic Church in France, put an end to the rupture caused by the reforms carried out by the church, and the confiscations that took place during the French Revolution.
This agreement, gave the first Consul (Napoleon), the right to nominate bishops, and new seminaries were established.
I’m assuming your asking if your supposed to use “a” or “an”.
Since where your putting a/an is followed by the word ordinary, which starts with the vowel “o” you would use the word “an”. Anytime the following word starts with a vowel you use an.
