 ## Exception messages
 
-Sometimes it is necessary to [raise an exception](https://docs.python.org/3/tutorial/errors.html#raising-exceptions).
+Sometimes it is necessary to [raise an exception][raising-exceptions].
 When you do this, you should always include a **meaningful error message** to indicate what the source of the error is.
 This makes your code more readable and helps significantly with debugging.
-For situations where you know that the error source will be a certain type, you can choose to raise one of the [built in error types](https://docs.python.org/3/library/exceptions.html#base-classes), but should still include a meaningful message.

+This particular exercise requires that you use the [raise statement][raise-statement] to "throw" multiple `ValueError`s.
 In the first scenario, you will need to raise a `ValueError` when either one or both of the people passed to the `RelativeDistance.degree_of_separation` method are not present in the family tree.
+
+```python
+# Example when Person A is not in the tree.
+raise ValueError("Person A not in family tree.")
+```
+
 If both people are present in the family tree, you will need to raise a `ValueError` when there is no valid connection between them as defined by the rules.
-The tests will only pass if you both `raise` the expected `exception` type and include the expected message with it.
 
-Please check the tests and their expected results carefully, as these instructions are not exhaustive.
