 #### Problem
 
-This anti-pattern happens when Elixir basic types (for example, *integer*, *float*, and *string*) are abusively used in function parameters and code variables, rather than creating specific composite data types (for example, *tuples* and *structs*) that can better represent a domain.

-We can create an `Address` struct to remove this anti-pattern, better representing this domain through a composite type. Additionally, we can modify the `process_address/1` function to accept a parameter of type `Address` instead of a *string*. With this modification, we can extract each field of this composite type individually when needed.
+Possible solutions to this anti-pattern is to use maps or structs to model our address. The example below creates an `Address` struct, better representing this domain through a composite type. Additionally, we can modify the `process_address/1` function to accept a parameter of type `Address` instead of a *string*. With this modification, we can extract each field of this composite type individually when needed.
