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.

An inhabitant shouts, "Either I'm a _____ or it is day, but not both," but you can't quite hear her over the torrential rain outside. She said either 'day-knight' or 'night-knight'.

You couldn't figure out her type, so you ask her what type she said she was in her prior statement, so she shouts again, "I said I'm a day-knight!"

You're still not sure, so you directly ask what type she is. She replies, "I'm a day-knight."

What type is she? Is it day or night? What did she say in her first statement?

What type is she?  'night-knight'.

 

Is it day or night?         day

What did she say in her first statement?                  " Either I'm a 'night-knight'or it is day, but not both"

SHE LIED 3 TIMES IN A ROW
