Ques:Read the following article and select the best answer. Article: Several years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Later he decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual example farm for hydroponics. The farm is on a boat called the Science Barge. Rainwater and river water are used to grow lettuce, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems. Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems. Experts say green roofs usually do not get much above 27degC. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water. Earlier in 2008, researchers in Texas reported that green roofs can reduce a building's air conditioning costs by about onefifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers say the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere. Question: The advantages of green roofs are mentioned in the passage EXCEPT _ . - changing the local weather - prolonging the roof's life - keeping the house cool - reducing the house's air conditioning costs

Ans:changing the local weather

Ques:Read the following article and select the best answer. Article: A group of teenagers: they laugh and talk over each other, dance and make faces -- you wouldn't believe they had just played on the same stage as famous American singers Kid Cudi and Eminem. These seven kids, all under the age of 20, are members of the band Kids These Days (KTD). Fresh out of high school, the band already has done things that most teens couldn't even imagine. They played at festivals including the recent SXSW in Austin and Lollapalooza in their hometown, Chicago, to crowds of loyal fans. KTD uses a mix of hip-hop, jazz, blues and classic rock to make a sound of their own. "KTD simply mixes most, if not all of my favourite music styles," said Kamia Jones, as Chicago high school student."I like that they aren't afraid to be different and that their music is real and speaks to the soul." The band formed two years ago. Now, as well as local fans, they are becoming popular around the world. Their facebook page is filled with supportive posts from admirers from California to Tokyo. "It's really strange to me that people from London, Australia and Russia... They have heard of us and they like our music because it's really cool feeling," says Marcie Stewart, who plays keyboard for the band. Despite their recent fame, KTD is a group of normal teenagers and they remain very close to one another. While talking to the reporters, they dance and make fun of each other. When asked what advice they would give to other teen musicians, Greg Landfair, KTD's drummer, said, "Keep your heart in it. Never lose the music and what you are doing, because that's what you're here for. Let the music always be first." Question: What do we know about KTD? - They are all of the same age. - They are as famous as Kid Cudi and Eminem. - There are five members in the band. - They have fans around the world.

Ans:They have fans around the world.
