@evan Did you know that there's a significant Irish legacy in Buenos Aires? One of the largest Rugby teams in Buenos Aires is called Hurling Club - one of their former scrum halves was the great-great-great-grandson of Galway born Patrick Lynch, although he was better known later as Che Guevara. A Mayoman called William "Guillermo" Brown founded the Argentine Navy. And there are around 650,000 Argentinians of Irish descent!

You are shown a set of four cards placed on a table, each of which has a number on one side and a color on the other.

The visible faces of the cards show yellow, 5, 4, purple.

Which card(s) must you turn over in order to test that if a card shows an even number on one face, then its opposite face is purple?

@christianp This reminds me of the Veritasium episode where he asked people to figure out a rule, and gives them a set of three numbers that follow the rule: 1, 2, 4. Their job is to offer other strings of 3 numbers and be told whether they do or do not follow the rule, and based on this, guess the rule.

@christianp everyone without fail starts by guessing 2, 4, 8 or 8, 16, 32. And yes, those follow the rule. They never think that they are only getting new information if they find sequences that don't follow the rule, then concentrate on how they are different.
