Where can you place an apple so that all but one person can see it
To find the answer to this riddle, you need to think about the concept of perspective. In order for all but one person to see an apple, you need to place it in a position where it is visible from certain angles but not from others. Here's a possible solution:
You can place the apple on a person's head. If everyone is standing in a circle and facing inward, the person with the apple on their head will not be able to see it, while everyone else will see the apple.
To verify this answer, you can try visualizing the scenario or even act it out with some friends. By placing an object on someone's head and positioning yourselves in a circle around them, you can confirm that only the person with the apple on their head is unable to see it while everyone else can.
Remember, riddles often require creative thinking and considering different perspectives.
