When you spill something, immediately clean it up.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement suggests that when you spill something, you should immediately clean it up. However, this is not always true. The appropriate response to a spill depends on the type and quantity of the spilled substance, as well as the surface it has been spilled on. For example, if you spill a small amount of water on a tiled floor, it may not be necessary to clean it up immediately. In some cases, it may be more appropriate to assess the situation and determine the best course of action before cleaning up the spill.
