ch7 textbook question

• Question 3

  1 out of 1 points

  	You are presented the following cards:  All the cards have a number on one side, and a colored face on the other. Someone states the following: "If a card has an even number on one side, then the opposite side will be red".  Which cards do you have to turn over to falsify this statement?
  	The card showing "8" and the one showing the brown face.  The card showing "8" and the one showing a red face.  Only the card showing "8".  Only the card showing "3".  I don't understand why option #2 is not accurate (which is what I picked). What material from ch7 can I utilize to answer this question?

This relates to Popper's concept of falsification. The cards you would need to turn over are the cards that could make the statement false. Some cards seem like they should be turned over, but in fact what is on the other side doesn't matter as far as this task is concerned. This is from a famous study called The Wason Selection task, which you could read about on Wikipedia if interested.
