Show Hint
Sulphur, salts and limestone are important chemical minerals.
Chemical industries use many non-metallic minerals.
Chemical industries exist in both public and private sectors.
- Only I, II and III are correct.
- Only I, II and IV are correct.
- Only I, III and IV are correct.
- Only II, III and IV are correct.
The Correct Option is A
Solution and Explanation
• Chemical-based industries manufacture a wide variety of products such as fertilizers, petrochemicals, synthetic fibres, plastics, paints, detergents, pharmaceuticals and industrial chemicals.
• These industries depend mainly on raw materials obtained from minerals, petroleum and natural gas.
• Many chemical industries also use non-metallic minerals such as sulphur, limestone, gypsum, phosphates and salts.
• Chemical industries are found in both the public and private sectors. Therefore, they are not completely controlled by the government.
• India has one of the largest chemical industries in Asia, contributing significantly to industrial production and exports.
Step 1: Evaluate Statement I
Statement I: These industries use natural chemical minerals.
• Chemical industries depend upon naturally occurring chemical minerals.
• Minerals like limestone, sulphur, phosphates and rock salt are widely used. Hence, \[ \boxed{\text{Statement I is Correct.}} \]
Step 2: Evaluate Statement II
Statement II: Some of the items used in these industries are petroleum, salts, sulphur, etc.
• Petroleum is the basic raw material for petrochemical industries.
• Sulphur and salts are essential inputs for many chemical products.
• Therefore, this statement is correct. Hence, \[ \boxed{\text{Statement II is Correct.}} \]
Step 3: Evaluate Statement III
Statement III: Many chemical-based industries use non-metallic minerals.
• Non-metallic minerals such as gypsum, limestone and phosphates are important raw materials.
• Hence, this statement is also correct. Therefore, \[ \boxed{\text{Statement III is Correct.}} \]
Step 4: Evaluate Statement IV
Statement IV: All chemical-based industries are under government control.
• This statement is incorrect.
• Many chemical industries are owned and operated by private companies.
• Only some strategic industries are managed by the government. Hence, \[ \boxed{\text{Statement IV is Incorrect.}} \]
Step 5: Choose the correct option
Only Statements I, II and III are correct. Therefore, \[ \boxed{\text{Correct Answer = (A) Only I, II and III are correct.}} \]

Read the passage carefully and answer the questions that follow:
Hunting and Food Gathering
The earliest human beings depended on their immediate environment for their sustenance. They subsisted on: (a) animals which they hunted; and (b) the edible plants which they gathered from forests in the vicinity. Primitive societies depended on wild animals. People located in very cold and extremely hot climates survived on hunting. The people in the coastal areas still catch fish though fishing has experienced modernisation due to technological development. Many species, now have become extinct or endangered due to illegal hunting (poaching). The early hunters used primitive tools made of stones, twigs or arrows so the number of animals killed was limited. Gathering and hunting are the oldest economic activity known. These are carried out at different levels with different orientations. Gathering is practised in regions with harsh climatic conditions. It often involves primitive societies, who extract both plants and animals to satisfy their needs for food, shelter and clothing. This type of activity requires a small amount of capital investment and operates at very low levels of technology. The yield per person is very low and little or no surplus is produced.- Examine the role of climate, water availability, and soil fertility on the distribution of world population.
