Fire produced by burning oil can be controlled by water.

Answer

### Step-by-Step Solution:

1. **Understanding the Statement**: The statement claims that fire produced by burning oil can be controlled by water. We need to evaluate whether this is true or false.

2. **Analyzing the Behavior of Water and Oil**: When water is poured onto burning oil, it does not mix with the oil. Instead, water is denser than oil, which causes it to sink to the bottom of the burning oil.

3. **Evaporation of Water**: As the water sinks, it heats up rapidly due to the high temperature of the burning oil. This causes the water to evaporate quickly.

4. **Expansion of Water Vapor**: When water evaporates, it expands significantly. This rapid expansion creates steam, which can push the burning oil away from the source of the fire.

5. **Spreading of Fire**: The expansion of steam and the movement of burning oil can cause the fire to spread in all directions, rather than being controlled or extinguished.

6. **Conclusion**: Therefore, the statement that fire produced by burning oil can be controlled by water is false. Water does not extinguish the fire; instead, it can make the situation worse by spreading the flames.

### Final Answer:
The statement is false. Fire produced by burning oil cannot be controlled by water because water sinks, evaporates, and expands rapidly, causing the fire to spread.
