Read the following passage carefully and answer the questions given below.

Natural fibre, any hairlike raw material directly obtainable from an animal, vegetable, or mineral source and convertible into nonwoven fabrics
such as felt or paper or, after spinning into yarns, into woven cloth. A natural fibre may be further defined as an agglomeration of cells in which
the diameter is negligible in comparison with the length. Although nature abounds in fibrous materials, especially cellulosic types such as cotton,
wood, grains, and straw, only a small number can be used for textile products or other industrial purposes. Apart from economic considerations,
the usefulness of a fibre for commercial purposes is determined by such properties as length, strength, pliability, elasticity, abrasion resistance,
absorbency, and various surface properties. Most textile fibres are slender, flexible, and relatively strong. They are elastic in that they stretch
when put under tension and then partially or completely return to their original length when the tension is removed.
Natural fibres can be classified according to their origin. The vegetable, or cellulose-base, class includes such important fibres as cotton, flax, and
jute. The animal, or protein-base, fibres include wool, mohair, and silk. An important fibre in the mineral class is asbestos.
The vegetable fibres can be divided into smaller groups based on their origin within the plant. Cotton, kapok, and coir are examples of fibres
originating as hairs borne on the seeds or inner walls of the fruit, where each fibre consists of a single, long, narrow cell. Flax, hemp, jute, and
ramie are bast fibres, occurring in the inner bast tissue of certain plant stems and made up of overlapping cells. Chemically, all vegetable fibres
consist mainly of cellulose, although they also contain varying amounts of such substances as hemicellulose, lignin, pectins, and waxes that must
be removed or reduced by processing.
The animal fibres consist exclusively of proteins and, with the exception of silk, constitute the fur or hair that serves as the protective epidermal
covering of animals. Silk filaments are extruded by the larvae of moths and are used to spin their cocoons.
With the exception of mineral fibres, all natural fibres have an affinity for water in both liquid and vapour form.
