Her short story entitled "The Shower" won the first prize in the writing contest.
Here's why the changes were made:
* "The Shower" in quotes: Titles of short stories are enclosed in double quotation marks.
* Capitalization of "The Shower": Only the first word of a title is capitalized, unless it contains a proper noun (like a person's name).
* Capitalization of "Writing contest": While "writing" is a common noun, "contest" should be capitalized because it's part of a proper noun (a specific writing contest).
* "The" before "writing contest": We need to include the article "the" to indicate a specific writing contest.
The corrected sentence now follows proper capitalization and punctuation rules.
