How did viewing a diff between two versions of a file help you see the bug that
was introduced?

The output of an application as "diff" shows you the numbers of lines,
and the content of them, of two compared files when differences
exits. So you can see the reason of the bug easily.

How could having easy access to the entire history of a file make you a more
efficient programmer in the long term?

Having a history of the changes introduced in the code along the time.

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?

The advantage is that you haven't got too small commit because you can
select the instant of time when you commit the changes, p.e. when a
bug is fixed in a function. In the other hand, the disadvantage is
that the commit could be too big, because it contents a lot of changes
in the code, not all related.

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?

Because systems like Git were designed to work with big software
project, where a lot of files are related between them, and systems
like Google Docs were designed to work with singular files. 

How can you use the commands git log and git diff to view the history of files?

The command "git log" returns a resume of all commits doing, showing
ID of the commit, name of file changed, author, date and the text
associated to the commit which must be a description of it.

Using IDs returned by the command "git log", in the command "git diff"
you can see the differences between two commits.

How might using version control make you more confident to make changes that
could break something?

Using version control you can revert any change using a "checkout"
command. So if you do a commit when you do some changes in part of
your code, you always could revert them using a "checkout".

Now that you have your workspace set up, what do you want to try using Git for?

I want use Git in a software proyect to control the versions and
changes on it.
