Solve the following Wason card selection task. The rule is: "If there is a vowel on one side of the card, then there is an even number on the other side." There are four cards in front of you, showing: A, C, 4, 7. Which two cards do you need to turn over to test this rule?

To test the rule, we need to find a card with a vowel on one side and an odd number on the other side. We can rule out option C (C and 4) because even if C has a vowel on one side, the other side does not necessarily have an even number. We can also rule out option D (7 and C) because if 7 has a vowel on one side, the other side does not necessarily have an even number. Therefore, the best choice is option B (A and 7) because if A does not have an even number on the other side or if 7 does not have a vowel on the other side, the rule is violated.
