The correct answer is Subjective. Here is the Python function to display words starting and ending with a vowel: ```python def display_vowel_words(): vowels = "aeiouAEIOU" try: with open("Report.txt", "r") as file: content = file.read() words = content.split() for word in words: # Strip common punctuation to accurately check the last letter clean_word = word.strip(".,!?") if len(clean_word) > 0: # Check if both first and last characters are vowels if clean_word[0] in vowels and clean_word[-1] in vowels: print(clean_word, end=" ") except FileNotFoundError: print("File Report.txt not found.") # --- Example Usage --- # display_vowel_words() ``` **Explanation:** 1. **`vowels = "aeiouAEIOU"`**: A string containing all lowercase and uppercase vowels for easy membership checking. 2. **`file.read().split()`**: Reads the entire file content and splits it into a list of words based on whitespace. 3. **`word.strip(".,!?")`**: This step is important! In the example string `"village."`, the last character is a period `.` instead of `e`. Stripping punctuation ensures we accurately check the actual last letter of the word. 4. **`clean_word[0]` and `clean_word[-1]`**: Retrieves the first and last character of the word. 5. **`print(..., end=" ")`**: Ensures the output is printed on a single line separated by spaces, exactly as requested.
