Example Input: Article: Generational differences and the economy are shifting more responsibilities for children from their parents to grandparents, according to a new survey. More than one-third of grandparents aged 50 and older contribute financially to their grandchildren's upbringing, and 11 percent have a grandchild living with them, the poll by AARP, the group for 36 million older US citizens, showed. Forty percent of people who responded to the telephone survey, whose average age was 69, reported spending more than $500 on grandchildren over the past year beyond traditional gifts.Education costs accounted for 53 percent, daily expenses for 37 percent and medical costs for 23 percent.Sixteen percent provided daycare for grandchildren. "They are the safety net for American families, helping to pay for practical expenses and necessities," said Amy Goyer, AARP's multi-generational and family issues expert. "We see many providing daycare services, while growing numbers even have grandchildren living with them," she said, referring to the 16 percent who watch their grandchildren while the parents are at work or school. Generally nearly 90 percent of the 1,904 grandparents questioned said they play a very or somewhat important role in their grandchildren's lives, and about 70 percent live within 50 miles of the closest one. The poll conducted by Woelfel Research Inc.also showed that grandparents were increasingly keyed to the younger generation's life issues and preferred ways of communicating. More than one-third connect with their grandchildren via email or text messaging, while half said they routinely discuss topics ranging from values and spirituality to drug and alcohol use. Nearly 40 percent said they had discussed dating or sex with at least one grandchild.Some 60 percent said they spoke with their grandchildren at least once a week. Most of the grandparents said they had five or more grandchildren, while one-fourth said they had grandchildren of a different race or mixed race.

Options: (A) the differences between generations are huge (B) how Woelfel Research Inc.conducted the poll (C) parents are the safety net for American families (D) grandparents take more responsibilities for grandchildren

Example Input: Article: 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 what Ofcom calls "media stacking" at least once a week. For TV viewers, the Internet scanning is the most popular activity, but they are also calling friends on the phone or sending emails and texts. Surprisingly, 12% claim to have listened to the radio with the television on, and 6% say they have watched another video in the meanwhile.
