 2. The broken code has mostly the same issues as exercise 1. Here are
     the problems that excercise 1 doesn't have:
 
+    - The if-elif-else has a blank line at a confusing place. Delete it.
+    - After deleting the code, it looks quite dense. Add a new blank
+      line before the `if`.
     - The elif line is missing a `:` at the end.
     - On the last line the comma is on the wrong side. `"bla bla,"` is
-        a string that **contains** a comma, but `"bla bla",` is a
-        string and a **separate** comma. In this exercise, the last
