To find preclosure points in a short story, consider the story's themes and how they are being addressed. If they seem to be coming to a satisfactory resolution or conclusion, that could be a sign. Also, notice if the conflicts presented earlier in the story are being resolved or if the characters have achieved their goals. These can all be indicators of preclosure.
One way to find preclosure points in a short story is to analyze the story's structure. See if there are any key events or turning points that start tying up loose ends or leading towards a conclusion. Sometimes, the author might hint at a preclosure through changes in the tone or mood of the narrative.
You can look for plot twists or climactic moments that might indicate a preclosure point. Also, pay attention to character developments and resolutions that could signal the approach of the end.
