Entretenido, ¿eh?

En consonancia con el ejercicio de lógica que ya le pasé a mucha gente (y que repito más abajo, para todos auqellos que no lo hayan hecho ya), aquí añado otro problema genial, esta vez sacado de un libro Working Wonders, de Jenny Colgan, que además tiene muchas referencias (directas e indirectas) al mito del Rey Arturo. Es un libro genial, lleno de lenguaje coloquial (lo cual está genial para aquellos que como yo quieren refrescar su inglés con un poco de 'slang'). Pero basta de rollos, en un momento del libro los protagonistas se encuentran frente a la puerta de un castillo con varias palancas (una roja, una azul y otra verde) y un acertijo para que descubran cuál es la que abre la puerta. Y el acertijo dice...

On the red lever is said: 'I open this door'

The blue lever said: 'I do not open this door'

The green lever said: 'The blue lever does not open this door'

One of these statements is true. One is false. One is either true or false.

You have one chance at pulling a lever

¿De qué palanca tirariais? Y lo más importante, ¿por qué?

Por cierto, ya vi que os gustó mucho el rompecabezas de las casas... Me alegro mucho oye, por si alguien no lo recibió... Now in English...
