Read the passage given below and answer the question (86 to 90) that follow selecting the most appropriate alternative for each.
Most paper comes from wood. First trees are cut down and the logs are taken to the paper mill. There, the logs are washed and cut into small pieces. These pieces are then put into ‘pulp digesters’ where they are broken down by steam and chemicals. This process releases wood fibre. This is mixed with dyes to form wood pulp which is then passed through screens to remove the hard pieces which have not dissolved.
The wood pulp is fed into a paper-making machine. A pump sprays a thin layer of the liquid paper pulp into a moving wire screen.
As the pulp is carried along by the screen the water in it slowly forms into paper. After this, the wet
paper is pssed through heated rollers which press and dry it. The dried paper is rolled into huge bundles and sent out for various uses.

- A pump ______
(a) spread the paper pulp on the wire screen. (c) flatten the paper.
(b) removes the hard pieces of wood (d) adds dyes to the wood pulp.
- The heated rollers are used _____.
(a) to bundle the paper (c) to dry the paper
