If the door did not conceal a hungry tiger, what was behind it?

If the door did not conceal a hungry tiger, then it will have a beautiful lady behind it, ready to be married to him.

Explanation:

Frank R. Stockton's short story "The Lady or the Tiger" is an allegorical story about a public trial started by a semi-barbaric king. He gave two choices for whoever is on trial. And this justified the fate of the person on trial, for his own choice will determine his fate.

A king of a land had decided on making use of a public trial where an accused person will be given the choice of choosing his own fate. Their guilt or innocence will be decided by a game of chance, and as it will be the individual's choice to choose, the blame will be on no one else except his own self. There came an issue where his own daughter had fallen in love with a man from a lower status. So, he made the man chose between two doors, one leading to a beautiful lady who will immediately be married to him and another, a hungry tiger who will obviously kill him. This choice of either one will make sure that he doesn't marry the princess even if he survives. This is the king's way of saving his daughter and also his honor.

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.
