Other products gotten from Petroleum include the following EXCEPT:

1. Analyze the question The question asks which item is NOT a product derived from petroleum (crude oil). This is an "EXCEPT" question, so we are looking for the odd one out.

2. Explain the concept Crude oil is refined through fractional distillation and petrochemical processing. Besides fuels, it gives many by-products:

• Fuels and lubricants: petrol, diesel, kerosene, aviation fuel, engine oil, grease
• Petrochemical products: plastics, synthetic fibres, paints, solvents, detergents, insecticides and pesticides, fertilizers, asphalt/tar, wax
• Synthetic rubber: this is made from petrochemicals

3. Check each option

• A. Rubber: Natural rubber comes from the latex of rubber trees (e.g. in Edo and Delta states), not from petroleum. Synthetic rubber does come from petroleum, but the question's "rubber" is taken as the natural plantation crop, so it is the one that fits the "EXCEPT" pattern here.
• B. Fuel: A direct product of petroleum refining.
• C. Paints: Petrochemical solvents and resins are used to make paints.
• D. Insecticides: Many are made from petrochemical compounds.

4. Answer Fuel, paints and insecticides are clearly petroleum products.

A note on this: strictly speaking, synthetic rubber is a petroleum derivative, so the question is a little loose. In the exam, though, A is the intended answer because natural rubber is the well-known source of rubber in Nigerian economics.

5. Exam tip For "EXCEPT" questions in Economics, first identify the three options that clearly belong together (fuel, paints, insecticides are all petrochemical products), then pick the one that fits a different category. Remember: Rubber = tree crop; Petroleum = fuels + petrochemicals.
