# checking if the hash grocery_item has a value of bread
if grocery_item.has_value?("Bread")
# if the hash grocery_item does have bread
# make a new key named food and set it to true
grocery_item["food"] = true
end
#value stored in the array will be the value of the item in grocery_item hash
grocery_list = [grocery_item.values_at('item')]
#grocery_list = ["Bread"]

The second the last line of Ethan's code uses the values_at method to return the value of the key 'item', which in this case is "Bread". The hash structure is like this:
"key" => "value"
Check out the Ruby Docs here for more on how hashes and their methods work: http://ruby-doc.org/core-2.2.0/Hash.html
