1. In three boxes, there is one ball each: white, red, and blue. The first box has the inscription "white," the second - "red," and the third - "white or blue." None of the inscriptions are correct. Where is what located?
1. Answer: blue, white, red.

The third box does not contain a white or blue ball. Therefore, it is red. The first one is not white, nor is it red. Therefore, it is blue. It follows that the second box contains the white ball.
