Challenge 2 / 2

After running composer require to install a Symfony "pack", how many new libraries will you have in your app?

You'll only have 1 new entry in your composer.json file, but because a pack requires other libraries, it will actually install as many libraries as the pack requires.

None: a pack is an "empty" library that exists just to trigger a recipe.

You'll have one new entry in composer.json for each library that the pack requires (but you won't have the actual pack itself there)
