Poll． Many people use the five-second rule． The rule says that fallen food is safe to eat if it has been on the floor for less than five seconds． Can people really use the five-second rule to save a dropped sandwich？ Or should they throw it and make a fresh one？

Anthony Hilton studied the five-second rule too． He is a professor of Life and Health Sciences． Hilton found that a dry food on the floor collects fewer bacteria than a wet food． Hilton also found that carpeted floors pass fewer bacteria than wood floors． Still， one should be
careful． \，\． \drop a dry food in your house， it's usually okay if you pick it up very quickly． Most clean homes don't have bad bacteria．\
Should you eat food that was dropped on the kitchen counter？ Dr． Steven Dowshen is a doctor for children． He says that floors are not the only place that can make food unsafe to eat． \，\． This is because raw foods sometimes have bad bacteria called salmonella． These raw foods can be on kitchen counters． \， they can get very sick，\．

A. People should not eat a dropped sandwich on any places．
B. People cannot eat food that is on the floor because of salmonella． C. People need to consider the type of the dropped food before eating．
D. People should be careful about the food dropped on the kitchen counter． 31. What's the writer's purpose of writing the passage？ ______
A. To introduce the five-second rule to people． B. To encourage people to use the five-second rule．
