For an investigation a teacher dropped a bolt into a container of maple syrup and asked students to remove it without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out. Which of these best describes some of the bolt's physical properties? (5.5A)

• The bolt is magnetic and has the same density as the maple syrup.

• The bolt is nonmagnetic and more dense than the maple syrup.

• The bolt is nonmagnetic and less dense than the maple syrup.

• The bolt is magnetic and less dense than the maple syrup.
