Challenge 2 / 2

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

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

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.

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)
