Gina's group classified their mineral samples based on relative hardness. They considered the minerals that have a hardness of less than five as relatively soft, and those with a hardness of five or above as relatively hard. They showed their groupings in a table. A 2 column table with 3 rows. The first column is labeled Relatively soft minerals with entries: Bornite, Chalcopyrite, Goethite. Second column is labeled Relatively hard minerals with entries: Hematite, Pyrite, Pyrrhotite.
What does Gina’s group need to do to correct the information in the table?
Bornite needs to be switched with pyrite.
Pyrite needs to be switched with goethite.
Goethite needs to be switched with pyrrhotite.
Pyrrhotite needs to be switched with hematite.
