-    It's your time to check if a password meets certain requirements. 
-    Use the following defined variables `password_length` and 
-    `has_special_characters` to evaluate if the password is secure.
+    You are given two variables that describe properties of a password:
+    
+    - `password_length` - represents how many characters are in the password
+        (`#!python int`)
+    - `has_special_characters` - represents whether the password contains 
+        special characters (`#!python True`/`#!python False`)
+    
+    Variables to use:
 
     ```py
     password_length = 18
     has_special_characters = False
     ```
 
-    The password is secure if:

+
+    Write code that checks if this password is secure based on these
+    requirements:
+
+    1. The password must be longer than 10 characters
+    2. The password must contain special characters
 
-    - it exceeds a certain length (10 characters)
-    - and contains special characters.
+    Use comparisons and logical operators to create a single expression 
+    that evaluates whether **BOTH** requirements are met.
 
-    Use comparison together with logical operators to solve the task.

+    To increase security, a third variable is introduced alongside the 
+    previous password properties:
 
-    To increase security, a third variable is introduced, namely 
-    `already_used` which is a boolean value and indicates whether the password 
-    was already in use. Now, check if all of these requirements are met:
+    `already_used` - represents whether this password has been used before
+        (`#!python True`/`#!python False`)
 
-    - Has more than 10 characters
-    - Contains special characters
-    - and was not already used before
+    Variables to use:
 
     ```py
     password_length = 18
     has_special_characters = True
     already_used = False
     ```
 
+    Task:
+
+    Write code that checks if this password is secure based on these three
+    requirements:
+
+    1. The password must be longer than 10 characters
+    2. The password must contain special characters
+    3. The password must not have been used before

+    Build on your previous solution and evaluate whether all **THREE** 
+    requirements are met.
