    If we use a process of elimination, we know that some choices are ridiculous. So, Let's name a few facts: 1. Distillation is where we separate mixtures, based on how they vaporize. We boil the mixture, until one of the ingredients in the mixture vaporizes, and the other one is left behind. Are we gonna vaporize either aluminum or iron, just to get them to separate? Lol. No way. 2. Evaporation is where the surface of a liquid changes into a gas. I don't know about you, but I've never seen iron, or aluminum, evaporate. That'd be scary. 3. We could "observe the different densities." Yeah. We could stare at them all day long. Is that going to get them to separate? Probably not. ~~~~~~~~~~~ Given all that, we're only left with one correct choice. And in case you still don't understand, I'll give you a hint: The three main magnetic metals are...Iron, Nickel, and Cobalt.
