So in this painting by Magritte, noticing that there are no tracks under the train, there is no fire in the fireplace and there are no candles in the candlesticks actually more accurately describes the painting than if you were to say, "Well, there's a train coming out of a fireplace, and there are candlesticks on the mantle."
Así que en este cuadro de Magritte, al ver que no hay vías debajo del tren, ni fuego en la chimenea ni velas en los candeleros en realidad esto describe  con más precisión la pintura que si dijéramos:  "Hay un tren saliendo de la chimenea, y candelabros encima de la chimenea".
