+QUESTION_TEMPALTE = """Your task is, given a list of letters, to form a valid palindrome.
+
+A palindrome is a phrase that reads the same forwards and backwards.
+
+If there are multiple possible answers, only respond with one of them. You must use all the letters provided.
+
+Example:
+- Input: Form a valid palindrome using the following letters: a, a, b
+- Output: aba
+- Explanation:
+    - The phrase aba reads the same forwards and backwards.
+    - The output answer is a valid palindrome using all the letters provided.
+    - The answer is a string, rather than a list of characters.
+
+Now, form a valid palindrome using the following letters: {letters}
