I said, "Well, did you look at any of the stuff?" They said, "Yes, we did." "Did you understand anything?" "No, nothing." So I said, "Well, how long did you practice on it before you decided you understood nothing?" They said, "We look at it every day." So I said, "For two months, you were looking at stuff you didn't understand?" So a 12 year-old girl raises her hand and says, literally, "Apart from the fact that improper replication of the DNA molecule causes genetic disease, we've understood nothing else."
Les dije: "Bueno, ¿miraron algo del material?" Respondieron: "Sí, lo hicimos". "¿Entendieron algo?" "No, nada". Entonces dije: "Bueno, ¿cuánto practicaron antes de decidir que no entendieron nada?" Me dijeron: "Lo miramos todos los días". Y dije: "¿Durante dos meses estuvieron mirando algo que no entendían?" Entonces una niña de 12 años levanta la mano y dice literalmente, "Aparte del hecho que la replicación indebida de la molécula de ADN provoca enfermedad genética no hemos entendido nada más".
