Day-knights and night-knights (Posted on 2011-03-08) Difficulty: 1 of 5
There is a land where every inhabitant is either a day-knight or a night-knight. Day-knights tell the truth in the day and lie at night. Night-knights lie in the day and tell the truth at night. One inhabitant once said, "It is day." Is the inhabitant a day-knight or a night-knight?

If it is day, then they are telling the truth, so they are a day-knight. If it is night, then they are lying, so they are a day-knight. Either way, they are a day-knight.
