Okay. You're all going to hate me. I admit it. I fooled you. I tricked you. I pulled the famous old magicians tactic, diverted your attention away from the trick, pulled the wool over your eyes and fooled you. Please don't be too mad at me.
This was an exercise in observation, disguised as a survey. First I gave you a set up.
"There is a big birthday party for Janice and her friends and family."
Then I gave you a cast of characters.
"A lot of people have come to it. The list includes Alice, Bob, Cathy and Charlie, Donna, Eugene, George and Janet, Lucinda, Mark, Nancy, Olivia, Rose, Ruth and Sam, Terry and good old Will."
Then I gave you a list of options which I will ignore because they're not important. Then I gave you some instructions.
"Your assignment is to decide, in your opinion, which package Janet should open up first. Please leave the number of your choice on my email firstname.lastname@example.org"
Only one person answered this correctly. To John Knox, of the Blogspot Tigers, goes the grand prize of a genuine Tupperware magicians wand and the robe to match. Here's his answer.
Janet should not open any of the presents. It is Janice's birthday, as you stated at the top of the Weekend Survey. You also stated that Janet is one of the guests at the party (when you listed her in the guest list). Therefore, Janet won't be opening any of Janice's gifts!
Thanks for an interesting exercise.
