You are working in a bar. Your job is to prevent people under 18 from consuming alcohol. You come to a table with four people.
#1 is drinking a pint of lager.#2 is drinking orange juice.
#3 looks about 45 years old.
#4 looks about 13 years old.
Which of these people do you need to check more closely to be sure the drinking law is not being violated?
We can format this problem in the same way that we did the Wason Card Task.
Each card has the name of a beverage on the front, and an age on the back.
True or false: All cards with an alcoholic drink on the front have an age over 18 on the back.
Which of these four cards must you turn over to determine whether the rule above is true?
