Cyber Safety : Truth or Scam

• I received this email from Apple. I have an iPhone. I have an Apple ID, and I had some trouble logging in to my Apple ID the other day. Oh, no! My Apple ID has been locked! How am I going to download new apps, purchase music, and that new iBook I wanted?!? I'd better click on the button and update my authentification settings. Wait, what? Is this real?
    Our task was to take a look at the email, and look for clues to tell us whether this email is Truth or Scam. Then, we make a decisions if we should press the blue button or not.
