Can you tell fake news when you see it?

A study published in the journal Cognitive Research measured how often people can tell a photo has been doctored. When presented randomly selected photos -- some real, some altered -- only 60 percent of participants could pick out the manipulated photos. Of those, only 45 could pinpoint what had been altered. We've assembled a short version of the test used in the study. Can you tell which of these five photos are real or faked?
