Q: How did viewing a diff between two versions of a file help you see the bug
that was introduced?
A: Viewing diff between two versions of a file helps us see what changed from
the old version to the new version.

Q: How could having easy access to the entire history of a file make you a
more efficient programmer in the long term?
A: You can look at all the changes that have been made over time. Sometimes,
it can help you track down bugs which could have been introduced some time
ago.

Q: What do you think are the pros and cons of manually choosing when to create
a commit, like you do in Git, vs having versions automatically saved, like
Google Docs does?
A: Manually choosing when to commit gives users control over what the
individual commits mean. However, there is a possibility that a user might
forget to commit or commit too infrequently.

Q: Why do you think some version control systems, like Git, allow saving
multiple files in one commit, while others, like Google Docs, treat each file
separately?
A: Git is related to software development, and a software project often
consists of collection of related files. Google Docs is much more general, so
it can't assume anything about relationship between files.

Q: How can you use the commands git log and git diff to view the history of
files?
A: Command 'git log' tells us about all the commits along with their IDs. 'git
diff' between any two commit IDs tells us about the difference between the two
commits. Successively running 'git diff' over consecutive IDs allows us to
determine history of files.

Q: How might using version control make you more confident to make changes
that could break something?
A: With version control you have history of all the changes you have made, and
you can easily go to an earlier version of a file if needed. Therefore it make
you more confident in making changes because even if something breaks you can
always "revert the change". I must note that judicious use of comments during 
commits makes this process significantly easier.
