## 120.

This task, although simple, is somewhat unexpected.

Suppose I am either a knight or a liar and make the following two statements:

1) I love Linda.
2) If I love Linda, then I love Katy.

Who am I: a knight or a liar?
120. I must be a knight. If I were a liar, then statements (1) and (2) would be false. Suppose statement (2) is false. Then I would have loved Linda, but I would not have loved Katya. So, I would have loved Linda, which means statement (1) would be true. Therefore, it is impossible for both statements (1) and (2) to be false. Hence, I cannot be a liar.
