His pretentious use of abstract concepts to justify his own preferences
Explanation:
In the last sentence of the first paragraph, Ignatius’ reference to “theology and geometry” conveys his pretentious use of abstract concepts to justify his own preferences.
Ignatius makes use of religion and science to further his own cause and preferences.
I believe the correct answer is pleasant and attentive. The author is stating in the excerpt that he though he would be getting his freedom back because of his 'gentleness and good behavior.' He wanted everyone around him to feel happy but also to do good things in order to be free again.
