Food picked up just a few seconds after being dropped is less likely to contain bacteria  than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the "5 second rule" --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped. The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor flooring types (carpet, cement floor etc.) to toast, pasta, a biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist  foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time." The Aston team also carried out a survey of the number of people who employ the 5 second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those who would eat or have eaten food dropped on the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added, "Our study showed that a surprisingly large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule." The passage is developed probably by   _  . A) time B) space C) contrast D) example

For decades, families settled on the sofa to share the latest news and TV series, until additional bedroom TV, computer games and the Internet almost put an end to family rows over who held the remote control. Now, however, the traditional living room scene is making a comeback. A study by the communications watchdog Ofcom has found families are once again gathering around the main television set, but they are bringing their pads and smartphones with them. "The 1950s living room is making a comeback as a family entertainment centre," said Jane Rumble, head of media research at Ofcom. "We are watching on much better, bigger, and more delicate television sets, but we are coming into the living room holding our connected devices." While the family are coming together once more, comparisons with the past end there. With a range of smaller screens on hand, not everyone sitting on the sofa shares the same viewing experience. The coronation   may have drawn the undivided attention of 20 million viewers in 1953, but those watching the Queen's Jubilee celebrations 50 years later were as likely to be commenting online about BBC's broadcast as watching it. "Just a few years ago, we would be talking about last night's TV at work or at school," said a viewer, "Now, we're having those conversations live while watching TV, using social media, text and instant messaging." It is a behaviour of media meshing , whose influence was underlined during this year's Wimbledon men's tennis final. As Andy Murray pushed towards his victory, 1.1 million people worldwide sent an average of over two microblogs about the match. People use the Internet to enhance their television experience, for example, by reading a newspaper live blog about a football match while watching the action on the main screen. For a huge number of younger viewers, the portable screen offers a chance to do something unrelated, such as online shopping, listening to music or watching another television programme. Some 70% of 16-to-24-year-olds claim to be absorbed in... The passage is written to   _  . A) describe the changes connected devices bring to TV watching B) report the comeback of the traditional living room scene C) show the influence of connected devices on people D) present the different roles TV plays in people's life
