Final answer:
The statement that Git works on a local level is true; changes are saved locally on your computer before being shared with others via a remote repository.
Step-by-step explanation:
The statement Git works on a local level is true. When using Git, any changes you make in your repository are indeed saved locally on your computer first. Git is a distributed version control system, which means that each user's working copy of the code is also a full-fledged repository with complete history and full version-tracking capabilities, independent of network access or a central server. Committing changes, creating branches, and merging branches are actions performed locally. Only when you decide to push your changes to a remote repository or pull from a remote do the actions go beyond your local environment.
