【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Testing the five-second ruleYou may have seen a friend drop food on the floor, pick it up, and eat it, while declaring, “Five-second rule! ” It’s said that food dropped on the floor for five seconds or less is still likely to be clean.【1】.Students at Britain’s Aston University, led by microbiology professor Anthony Hilton, tested the rule and found it to have some scientific basis. The study’s results show that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer, according to Hilton.The students also found that the type of flooring where the dropped food lands has an effect. 【2】Bacteria are most likely to transfer from tiled (铺瓷砖的) surfaces to moist food when the food has stood there for more than five seconds.【3】 Therefore, consumers should still be cautious. “However, the findings of this study will bring some light relief to those who have been employing the five-second rule for years, despite a general consensus that it is purely a myth,” professor Hilton said in a statement.The research team at Aston also surveyed 500 people to find out who employs the five-second rule. Of the people surveyed, 87% said they would eat food dropped on the floor, or have done so in the past. 【4】 “Our study showed people are also more likely to follow the five-second rule, which our research has shown to be much more than an old wives’ tale,” Hilton says.Still, scientists say you should be careful about eating food dropped on the floor, especially if you have doubts about the cleanliness of the surface. 【5】

B. Carpeted surfaces posed the lowest risk. |
