So you don't want to have the mastodon charging at you and be saying to yourself, "A slingshot or maybe a spear might work. Which would actually be better?" You want to know all that before the mastodons actually show up.
Así que no querrán que el mastodonte se lance sobre Uds. y preguntarse a sí mismo: "Una honda o tal vez una lanza ¿Qué sería mejor?" Uds. quieren aprender todo eso antes que el mastodonte aparezca.
