What is ironic about miss prism's expressing concern for jack and admiration for his devotion to his brother? what kind of irony is this? this is a question from "the importance of being earnest" and i'm having trouble understanding what exactly it means.

This is the story entitled "The Importance of Being Earnest".

Miss Prism's expressing concern for Jack and admiration for his devotion to his brother are ironic because she knows from the start that Jack’s pretences of having a brother are eventually real. He then finds out that Algernon is his younger brother upon questioning Miss Prism at the last part of the story.

The story is an example of situation irony because the audience did not expect that Jack has a brother and that it will be Algernon, as opposite to their expected ending. 

Some cultural backgrounds have different superstitions or customs, this can play a part in how they decide things. superstitions are important to a culture for example, an asian culture has a superstition about women putting their purses on the ground their money will be gone, therefore people in that culture try everything they can to not let their purse touch the ground in fear of it being true. also like how we avoid walking under ladders in fear of bad luck. customs may also play a key role a custom also know as a tradition, is something people in the culture have been doing for generations as a quick example, if a family has a necklace that the family's mother passes it on to her daughter in so on it's a custom in that family.
