Astoryline involves two key things: theme and setting dialogue and description characters and conflict * excitement and emotion i think its the one with the *. is it right?

Characters and conflict

Explanation:

Characters and conflict are two absolutely necessary elements of a storyline. A story has many different components that are extremely important. However, these two are essential if we want the story to make sense. Characters refer to the people, figures or animals that drive the story forward. These take the actions that the story describes. Conflict refers to the main problem or struggle that the characters face in the story.

dramatic irony occurs when the reader/audience knows more about a character's situation than the character does. the one main effect is that it gives the reader a sense of superiority, or detached superiority. the reader not only seemingly discovers what is revealed, but feels superior for doing so.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
