Question

Maria works in a hardware store. A bin of aluminum nails and a bin of iron nails are knocked over, and the nails get mixed up. Both sets of nails are the same color and size.

What makes separating the nails a fairly easy job?

Aluminum is heavier and iron is lighter.
Iron settles in water, while aluminum floats.
Aluminum is magnetic, and iron is non-magnetic.
Iron is magnetic, and aluminum is non-magnetic.

Answer 1

The correct reason that makes separating the nails a fairly easy job is:

**Iron is magnetic, and aluminum is non-magnetic.**

This property allows for the use of a magnet to easily separate the iron nails from the aluminum nails.
