Manuel is using a pan balance to compare a toy bear and a baseball. The illustration shows the results.

What does the position of the balance show about the toy bear and the baseball?

• The balance shows that the mass of the of the toy bear is less than the mass of the baseball.

• The balance shows that the mass of the of the toy bear is more than the mass of the baseball.

• The balance shows that the mass of the toy bear and baseball are the same.

• The balance is not working properly.
