    Answer 3 out of 4 questions correctly.

A landfill is a place where trash is taken. Most of the trash in a landfill is crushed and buried. But trash made of certain materials can be recycled or sold. To find these materials, landfill workers must sort the objects in the trash.
The workers can sort many objects at once by using a magnet. Magnets
attract,
or pull on, objects made of certain materials. Objects that are strongly attracted to magnets will stick to them.
Jen, a landfill worker, has a crane with a big magnet. She lowers her crane's magnet over a pile of trash.
