7. True/False: In software engineering, 'refactoring' refers to the
process of adding new features to the software without altering its
external behavior.
Answer: False
Rationale: Refactoring is the process of restructuring existing
computer code without changing its external behavior to improve
nonfunctional attributes of the software.
