Input: Consider Input: Article: There are several ways to break the technology code that teenagers have written among themselves. The following are ideas to help parents understand the sometimes confusing world of the teens. SocialNetworking Sites: Sites like MySpace and Facebook _ all generations and are a good way for a parent to understand what social standards your teen is living with. There are many ways to help you take part in your child's online activities. You also can be from an onlooker who keeps a bird' s-eye view of his cyber world to an active member of his social group. MMORPG: Massively Multiplayer Online Role-Playing Game comes in the form of games. A child can easily become addicted to them if no limits are set. To fully understand the attraction behind MMORPG, you can make your own account and character to explore the digital world. Playing the online games may seem strange at first to your teen, but experience has led me to only positive feedback from young people who can communicate with adults about their gaming experiences. Text and Instant Messenger: The ways of teenage communication have produced a whole new language, such as "LOLZ" (laughing out loud) and "PSOS" (parent standing over shoulder). Learning the basic shorthand of teens can open up a whole new world of communication, not only talking to your teens, but being able to listen on their terms as well. You may just find yourself texting faster and ending your correspondence with TTYL (talk to you later). To teens, texting anyone looks cool, even Mom and Dad. Email: Emailing your child is easy. This, of course, cannot take the place of face-to-face communication, but it provides another way for your child to reach you. Another benefit is that your child cannot act like he didn't hear you.

Input: Consider Input: Article: To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn't a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater. "Planting tress is one way, but it isn't that simple. It doesn't solve the basic issue of water resources," says Wu Bo, a professor. "We need to calculate how much water the trees will absorb, or else it could have a negative effect." Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields using flood irrigation and earns a good income for his family. Other farmers haven't stuck it out : about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return. Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight. "With enough water, this problem can be solved," Lu says. "We can plant trees and grass, and they will grow bigger. That will stop the desert." Experts say that farmers could switch to drip irrigation to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to "Save Water, Protect the Environment".
Answer: it can make groundwater become less

Output: The negative effect of planting trees in deserts is that _ .

Input: Consider Input: Article: Instagram is containing so many photos of food--now a pop-up diner in London is taking advantage of this new trend by letting people settle the bill for their meals simply by uploading photos of their dishes to social networks. I always thought people's taking pictures of their food was kind of silly, but at this new pop-up restaurant in the UK, I'd probably do it too. 'The Picture House' is the world's first pay-by-photo restaurant--you order, click a photo of the food, share on Instagram and eat for free! The restaurant belongs to frozen food giant Birds Eye, who came up with the idea to cash in on people's addiction with photographing food and sharing the pictures online. They conducted a survey and found out that more than half of the British population regularly took pictures of their meals. So they realized it was a better way to advertise their new dining range. The pop-up diner was open in Soho, London for three days in May, and is now moving to other major UK cities. They serve two-course meals that customers don't have to pay for, if they photo and Instagram it. The restaurant is a part of Birds Eye's 'Food for Life' campaign, a new marketing project that aims at changing the way people look at frozen food. "Taking photos of food enables people to show off and to share their mealtime moments--from the everyday to the special," said marketing director Margaret Jobling. The reaction to The Picture House has been great so far. And the pay-by-picture concept has proven to be an effective way. Alternative payment methods are actually gaining popularity among a lot of businesses. Last year, in a cafe in Germany customers pay by how much time they spend there, not by what they eat.
Answer: a program used to share photos
Output: Instagram probably is _ .
