 However, you can see that we’ll hit a problem here, because we define an ambiguous symbol. We have
 two solutions:
 
 - Change the name of the `struct` to something else.
-- Qualified the `use`.
+- Qualify the `use`.
 
 The problem is that if we qualify the `use`, what name do we give the trait? We’re not even
 referring to it directly.
