D a lot of interesting research is being done about aging
I think that its either B, the host's responses to the woman, or C, the woman's excessive commentary. (I'm leaning more towards B, but i'm not sure.)
One example that establishes irony is woman asking if the musician is "grateful" for being introduced to white people and the host's contradictory response. I hope this helped! :)
The Situational Irony that occurred in "The Colomber" by Dino Buzzati was the fact that Stefano gave up his dream of becoming a sea captain to ensure that he will live a long life after seeing the Colomber.
It was believed that the Colomber was a harbinger of Death and that whoever sees it will be doomed for life.
However, the reason why the Colomber was after Stefano was because it was tasked to give Stefano a pearl that will give him good luck and success in life.
It is ironic because the reason Stefano feared the Colomber was false and baseless.
Is this a book or no cause you made it sound very confusing
