Not sure how to do this question!

Very confused what to do here. This is so far what I could come up with.

address_book =
def find_ by_phone_number(address_book) 
  results = []
  contacts.each do |contact|
    contact.phone_numbers.each do |phone_number|

Hi Daniel,

Call the find_by_phone_number method on the address_book instance and pass it any phone number.

Basically the question is all about "searching" on anything (i.e phone number, address, names, etc), then you just need to call phone number method. It doesn't need you to create extra definition method for this part.

Here's my example:

address_book =


Hope that helps.
