How does pure water increase the boiling temperature of water?

Pure water does not increase - or in any other way affect - the boiling teperature of water becasue the latter is normally taken to be that for pure water!

The question does not make sense. What type of water is it whose boiling temperature is meant to be increased by pure water? Impure water?

In any case, pure water does not increase the boiling point of water but lowers it.
