clarification

I do not understand the second requirement in the question below:

"Using the has_key? method, check if the hash variable has a key called "calories". If it does, set a new variable called food to true."

What is new variable? (hash, key or value)

hash.rb
hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }
hash.has_key?("calories")
food = "true"

Hi Rober.

This challenge asks that you set food to true ONLY IF hash has the key "calories".

so, if you combine line 2 & 3 of your code together, you'll have the correct solution.

hash = { "name" => "Bread", "quantity" => 1, "calories" => 100 }
food = "true" if hash.has_key?("calories")

hope this helps.
