Answer 1

The correct answer is (c) 5%–7%.

The best I can explain: The mixture of pulp (known as the furnish) is passed into the beater and brought to a consistency of 5%–7%. The beating makes the fibers more flexible, causing them to become relatively mobile and to deform plastically on the paper machine.
