Need someone to explain directions more for this problem as I am unsure what to do.

See code:

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

grocery_list = grocery_item.values_at(0)

Hi J,

Task 1: The idea is to build a conditional statement (if) that uses the boolean result of the .has_value?("Bread"). If the condition is true, you add an item to the grocery_list hash containing the key "food" and the boolean value true.

Task 2: Using the values_at method, create an array called grocery_list with the value of the grocery_item hash at the "item" key. Note: The values_at method returns an array containing the values associated with the given key(s).

Here is how I solved Task 1 and Task 2:

grocery_item = { "item" => "Bread", "quantity" => 1, "brand" => "Treehouse Bread Company" }
# Task 1
if grocery_item.has_value?("Bread")
  grocery_item['food'] = true
end

#Task 2
grocery_list = grocery_item.values_at("item")

Let me know if things are not clear. Please note that when solving a challenge, the code of Taks 1 should not be overwritten when solving Task 2.
