Assertion (A) : Copper smelting industry is often located near the source of raw material.
Reason (R) : Industries are usually located close to the source of raw material.
Which one of the following is correct ?
Answer: B
Both (A) and (R) are true but (R) is not the correct explanation of (A).
Copper ores contain only a small percentage of metal, so smelting loses most of the weight of the raw material. Under Weber's theory such weight-losing industries are pulled towards the raw material to save transport costs, which is why copper smelters stand near the mines, as at Khetri and Ghatsila.
The reason is a broad generalisation that is partly true, since many industries do locate near raw materials, but many others are market-oriented or footloose. The specific explanation for copper smelting is the large weight loss in processing, not a general rule, so R does not explain A.
