The correct Answer is:
To determine which object could have started the fire that Shalu observed, we need to analyze the situation step by step. ### Step 1: Identify the Smell Shalu noticed a strong smell of burning hair. This indicates that the material that burned has a similar chemical composition or properties to hair. ### Step 2: Understand the Composition of Hair Hair is primarily made of a protein called keratin. When it burns, it produces a distinct smell that is often described as similar to burning flesh or burning hair. ### Step 3: Consider Common Materials We need to consider common materials found in a bedroom that could produce a similar smell when burned. Some materials that might be present include: - Natural fibers (like wool or cotton) - Synthetic fibers (like nylon or polyester) - Other household items (like plastic) ### Step 4: Analyze the Options 1. **Wool**: This is a natural fiber and has a smell similar to burning hair when it burns. 2. **Nylon**: This is a synthetic fiber, and while it can burn, it does not produce a smell similar to burning hair. 3. **Cotton**: This is also a natural fiber but has a different burning smell compared to hair. 4. **Plastic**: This is synthetic and produces a very different smell when burned. ### Step 5: Conclusion Given the options, the most likely object that could have started the fire, producing a smell similar to burning hair, is **wool**. ### Final Answer The fire could have started from an object made of **wool**. ---

    You have seen homes, shops and factories caught in fire news, or in newspaper, or in real. Do you think how can the fire be controlled from spreding? Generally, water is used to control fire. Water brings down the temperature of the combustible substance below its ignition temperature. The water vapour surrounds the combustible material, thus helping in cutting off the supply of air. Fire produced by the burning of oil or petrol cannot be controlled by throwing water on it because water being heavier than oil, settles down the oil and oil continues to burn. In the case of fires caused by burning liquid fuels, such as kerosene oil can be controlled by throwing sand or soil over it. Read the below questions and try to answer them. What should you do if you use a carbon dioxide fire extinguisher?
