+## The Problem:
+
+We need to change the regex ```favRegex``` to match both the American English (favorite) and the British English (favourite) version of the word.
+
+  ## Solution:
+ 
+ ```js
+let favWord = "favorite";
+let favRegex = /favou?rite/; // Change this line
+let result = favRegex.test(favWord);
+```
+
+  ## Explanation:
+ 
+In this regex (```/favou?rite/```), we specify the possible existence of an element (```u```) with a question mark, ```?```.
