 // It returns  an array of key-value pairs from the object.
 // It is needed to iterate over each key-value pair in the input object.
 
 // d) Explain why the current return value is different from the target output
-// They are the same. Object keys are always strings, so the functions converts values into string keys and assigns the original key as the new value. 
+// The code incorrectly used invertedObj.key = value instead of invertedObj[key] = value,
+// which led to all values being assigned to the same key 'key' in the inverted object.
 
 // e) Fix the implementation of invert (and write tests to prove it's fixed!)
 // Invert function passes 4 edge case tests.
