Here is a answer to this (Everyone gets it wrong) Read the following passage.

Yesterday my friend Ana and I went downtown to go shopping. The streets were filled with people, and traffic was at a standstill. There were reporters and police officers everywhere I looked. Suddenly, Ana grabbed my hand and pointed down the block. "Look at that!” she exclaimed. I couldn’t believe what I was seeing—a giant elephant was walking down Broadway! Just then my phone rang. "Jana!” my mom yelled through the phone. "Be careful, there’s an elephant on the loose!” "Don’t worry, Mom,” I said, "it’s headed the other way.” Later, we learned that the elephant had been returned safely to the circus in time for Saturday’s performance.

Who would be the best primary source to interview about this event?

a member of the circus
Jana’s mom
Jana’s friend Ana < THIS One
the mayor of the town
