I don't think I understand the question

Do I suppost to use the Bread value on the array???

hash.rb 
grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company", "food" => true}
grocery_item.has_value?("Bread")
grocery_list = ["Bread"]
grocery_list.values_at("Bread")

If you're asking about task 2, they want you to write something like grocery_list = grocery_item.values_at 'item'

It's a weird question, because using values_at with a single argument is very similar to just using grocery_item['item'], except that what you get back is an array. I guess the idea is that you're starting a grocery list with a single new thing... but it's really stretching the bounds of what makes a realistic programming exercise.

For task 1, they are just asking you to check if the item is bread, in which case you'll add a new detail to the item, which is to say that it truly is food:

if grocery_item.has_value? 'Bread'
  grocery_item['food'] = true
end

Thank you for your help. Although, I understand the concept, I struggle to understand the question.
