No partial credit will be earned if only one correct choice is selected.

Solution
The two correct answers are:
- Replacing each instance of repeated code with a call to a procedure
- Replacing several lines of documentation with a single line of documentation
These two methods are ways in which a programmer can use abstraction to manage the complexity of a program. The first method reduces redundancy and makes the code more readable and maintainable.
