Match the objects given in column I with the materials given in column II. Column I Column II (a) Surgical Instruments (i) Plastic (b) Newspaper (ii) Animal product (c) Electrical switches (iii) Steel (d) Wool (iv) Plant product

(a) Surgical instruments — (iii) Steel Surgical Instruments should be rust free, sharp and strong so that the successful surgery can be performed. So we can use steel to make surgical instruments. (b) Newspaper — (iv) Plant product The newspaper is a paper in which news is written. These papers are manufactured from the trees, so we can say that they are the plant product. (c) Electrical switches — (i) Plastic Plastic is an insulator, so we can use it in electrical switches. (d) Wool — (ii) Animal product Wool is the fur obtained from the sheep, so we can say that it is an animal product.
