Read the following statements carefully and choose the correct option: Assertion (A): Iron and steel is considered a heavy industry. Reason (R): It requires lightweight raw materials like cotton and rubber.
- A.Both A and R are true, and R is the correct explanation of A
- B.Both A and R are true, but R is not the correct explanation of A
- C.A is true, but R is false
- D.A is false, but R is true
Correct answer
Explanation
The correct answer is C, A is true, but R is false. Iron and steel is indeed a heavy industry, but not because of light raw materials.
Industries are classified by the weight of the material they handle. A heavy industry uses bulky, heavy raw materials and turns out bulky products, so iron and steel, which consumes iron ore, coking coal, limestone, dolomite and manganese by the tonne, is the classic example. A light industry uses light raw materials and gives light finished goods, and it is here that cotton, rubber, silk and electronics belong. That is why the reason given is false: cotton and rubber are never the inputs of an iron and steel plant.
A is wrong as a choice because the reason is false. B is wrong for the same reason. D is wrong because the assertion about iron and steel being a heavy industry is perfectly true.
Exam tip: Heavy industry - iron and steel, cement, shipbuilding; light industry - cotton textiles, electronics, rubber goods.
