Input: Consider Input: Article: An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
Question: Why may Justin Bieber be sent into suborbital space?
Options: (A) To show his bravery and make him a role model for teenagers. (B) To arouse the American public's interest. (C) To help reform the spaceflight industry. (D) To film an advertisement about space.
Asnwer: B

Output: Yes

Input: Consider Input: Article: The Australian city of Sydney is experiencing its hottest day on record, with temperatures reaching nearly 46C. A temperature of 45.8C was recorded at Observatory Hill in the city at 14:55 local time. Some areas in the wider Sydney region were even hotter, with the town of Penrith, to the west, registering a temperature of 46.5C. Firefighters are still battling dozens of wildfires sparked by the intense heat in New South Wales and Victoria. The small town of Licola in eastern Victoria is reported to have been cut off by a 44,500-hectare fire, as its only access road is blocked. Officials said dozens of people had been evacuated but 10 locals were still there. Rob Gilder, a sheep farmer, said he and two employees had found themselves trapped on their farm and were "in grave danger". He told the Herald Sun they were taking steps to protect their house and farm equipment, but that he was concerned for his livestock, and that the situation could worsen. "I am very worried. But I am hopeful that one of those helicopters will come and get us but I think the smoke might beat them." Australia faces wildfires each year as temperatures climb. In February 2009, on what has come to be known as Black Saturday, 173 people were killed in fires in the state of Victoria. On Friday, Prime Minister Julia Gillard attended a memorial service for fires in 2003 in the capital, Canberra, which killed four people and destroyed thousands of homes. She reminded Australians to "take the appropriate precautions to stay safe and monitor information from local emergency services as they work to protect lives and property", the AFP news agency reports.
Question: What is the best title for the passage?
Options: (A) Sydney, a beautiful city. (B) Wildfires in Sydney. (C) High temperature in Sydney. (D) Prime Minister Julia Gillard
Asnwer: C

Output: Yes

Input: Consider Input: Article: EDGEWOOD-EVERY morning at Dixie Heights High School, customers pour into a special experiment; the district's first coffee run mostly by students with special learning needs. Well before classes start, students and teachers order Lattes Cappuccinos and Hot Chocolates. Then, durning the first period teachers call in orders on their room phones, and students make deliveries. By closing tome at 9.20 a.m., the shop usually sells 90 drinks. "Whoever made the chi tea, Ms. Schatzman says it was good," Christy McKinley, a second year student, announced recently, after hanging up with the teacher. The shop is called the Dixie PIT, which stands for Power in Transition. Although some of the students are not disabled, many are, and the PIT helps them prepare for life after high school. They learn not only how to run a coffee shop but also how to deal with their affairs. They keep a timecard and receive paychecks, which they keep in check registers. Special-education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia. Not that it was easy. Chevalier's first problem to overcome was product-related. Should school be selling coffee? What about sugar content? Kenton County Food Service Director Ginger Gray helped. She made sure all the drinks, which use non fat milk, fell within nutrition guidelines. The whole school has joined in to help. Teachers agreed to give up their lounge in the mornings. Art students painted the name of the shop on the wall. Business students designed the paychecks. The basketball team helped pay for cups.
Question: What is the text mainly about?
Options: (A) A best selling coffee. (B) A special educational program. (C) Government support for schools. (D) A new type of teacher- student relationship.
Asnwer: B
Output: Yes
