Zulema tiene 10 años y está cursando quinto grado en una escuela matutina. Al mediodía llega a la casa hambrienta, dispuesta a comer todo lo que encuentre. Devora la comida y, tras comer el último bocado, prende el televisor porque comienza la novela del medio día. A los 15 minutos llega Daniel, su hermano, que tiene 14 y cursa segundo año del secundario. Daniel también viene con hambre, así que rápidamente Zulema pone a calentar su comida. Mientras tanto, la niña disfruta de los minutos que le quedan para seguir la novela porque sabe que, apenas Daniel termine de almorzar, será desplazada por un programa deportivo. Sin embargo, ese día decide que va a ver su novela y apenas el hermano llega se para delante del televisor y le dice que esa vez la novela no se cambia y le aclara que a partir de ese momento ella va terminar de ver la novela todos los días porque llega antes. Como única respuesta el hermano la empuja fuertemente y le saca el control remoto de la mano. Entonce

good question. i'll be looking into that. (this is a joke sir)

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
