If you're talking about the story "Marian Andersen Sings," then I believe it would be that "They knew that she would be nervous"
Resolution
The resolution of the story is the end. All of the conflicts are solved and subplots are wrapped up. Tension usually builds as the conflict begins and becomes more complicated. The author does this through the sequence of events, language, conflict, sentence structure, tone, and mood. The resolution is not an area of tension in a story. If there is, usually it's so that there can be a sequel.
The answer is D. Exposition
Answer:
In the short story "The Open Window", the line that foreshadows the trick that the niece will play is option D, "Then you know practically nothing about my aunt?' pursued the self-possessed young lady". She want's to make sure Mr. Nuttel knows nothing about her aunt to trick him. Options 1 and 3 are parts of the story she invents and option 2 introduces this girl as a character. Once she is sure that Nuttel does not know her aunt she can begin with her mischief.
