I dream of a prosperous country where every Nigerian will live in dignity. I dream of an end to high levels of poverty, inequality and unemployment in Nigeria. I dream of a Nigeria where the rule of law will prevail and where there will be observance of human rights.
I dream of a Nigeria where governments at all levels will prioritize human capital development, and industrial development.I dream of Nigeria where every Nigerian child has access to quality education; a country with some of the best universities in the world that parents will see as the first choice for their children.
It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, based on the given lines above, the literary device that Sophocles uses in these lines to keep the audience interested is DRAMATIC IRONY. Hope this helps.
