Article: We've all heard about the power of positive thinking, but a recent study found that people who think they're getting fit actually get more positive benefits from activity, according to a Reuters Health article. The study examined hotel housekeepers over a period of four weeks. Some of the housekeepers were told that their work duties gave them enough activity to meet the Surgeon General's health guidelines . Another group of housekeepers were told nothing. After four weeks, the housekeepers who believed their work activity counted as exercise lost weight and body fat, and their blood pressure went down. The results of this study suggest that it's important to understand and believe in the positive benefits of your activity. So here are a few things to think about the next time you exercise: Just thirty minutes of quick walking each day can greatly reduce your risk of a heart attack. Even your housework -- like yard work and house cleaning -- can help you burn calories and increase your fitness levels. Weight bearing activity just a few times a week can build bone density and reduce your chances of developing osteoporosis . Three 10-minute workouts throughout the day are just as good to your health as one long workout. Moderate amounts of exercise have been linked to lower rates of heart disease, stroke and even cancer. Strength training can help make daily activities like carrying bags or laundry feel easier. Regular exercise will reduce stress, keep you in a good mood and improve the quality of your sleep. Question: It can be inferred from the passage that _ . Yes or no, is the answer "positive thinking does good to our health"?
Yes

Article: A new report says only about half of all students in the main school systems of America's largest cities finish high school. The report notes higher rates of graduation -- over 70% --in areas surrounding the cities. Researchers studied high school graduation rates from the 2003, 2004 school year. They also identified the nation's fifty largest cities. The largest, New York City, had a population of more than eight million. The smallest city was Wichita, Kansas. It had about three hundred and sixty thousand people. Researchers used a system of measurement called the cumulative promotion index to find graduation rates. School officials in many of the cities studied said the resulting numbers were too low. That is because different areas use different methods to find graduation rates. Critics say many methods do not give a true _ of the number of students who leave high school before finishing. Other studies have put the national graduation rate at about 70%. But experts agree that too many students are not completing high school. They estimate the number at more than one million each year. The report was prepared for America's Promise Alliance. The private group aims to help children receive services they need to succeed. General Colin Powell was chairman of America's Promise Alliance when it was formed in 1997. He attended the press conference Tuesday where the report was released. He said studies have shown that the US must do more to educate the leaders and work force of the future. Secretary of Education Margaret Spellings also spoke. She said the government will propose that states use the same methods when reporting graduation rates. Alliance officials also announced the start of a nationwide campaign to improve graduation rates. It is to include a series of meetings to be held in every state over the next two years. The meetings will bring together elected leaders, business owners, students, parents and education officials. They will develop plans to increase the number of Americans who finish high school. Question: The author wants to tell us _ . Yes or no, is the answer "too many Americans do not finish high school"?
(Answer)
Yes

Ques: Article: Your next Saturday night takeaway could be brought to you by a robot after a major food delivery company announced plans to use automated vehicles to transport meals. Europe's biggest online takeaway food company Just Eat has partnered with Starship Technologies to deliver food with robots on the streets of London later this month. "Nobody has ever done deliveries with land-based robots," said Allan Martinson, the chief operating officer of Starship. The robot courier can travel up to 4 miles per hour for about 10 miles. It uses a GPS signal and nine cameras to navigate . Instead of a person arriving at their door, customers could find themselves receiving a notification on their phone that says a robot is on its way and a code to unlock the automated courier. "Put the code in, the robot opens up, and there's your food," said David Buttress, chief manager of Just Eat. The robot, which has so far been tested in Greenwich, Milton Keynes and Glastonbury, costs PS1 to transport within 3 miles, compared with the PS3 to PS6 it costs for a human courier. To date 30 robots have driven nearly 5,000 miles without getting into an accident or finding themselves picked on by passers-by. They have driven in more than 40 cities around the world, including London and Tallinn, Estonia. An initial worry was how the public would react to robots. But Martinson said the public has been calm when passing the delivery machine on the streets. "The most surprising reaction has been the lack of reaction," said Martinson. Another significant fear was that people would disrupt the robots, or try to steal them and their contents. To prevent this, the robot is fitted with nine cameras, two way audio, and movement sensors that send a warning if it is lifted off the ground. And it opens only with a pass code provided to the customer via a notification. "It's much easier to shoplift than it is to steal a robot," said Martinson. Question: The test of Starship robots shows that _ . Yes or no, is the answer "the robot delivery is cheaper than human delivery"?
Ans: No

Article: Located along California's San Andreas Fault, the city of San Francisco is likely to take precautions(,) in the event of the next big earthquake. According to aNew York Timesreport, emergency planners in San Francisco are not only thinking of human evacuation(,) plans in the event of an earthquake, but also of how to care for pets during a natural disaster. Ideally, the planners will be able to train pet-disaster responders who work to evacuate dogs, cats and other household pets from the disaster site to one of the 125 temporary animal shelters that will be set up or, if the pet is injured, it will be brought to an emergency animal medical unit where there will be people on hand to tend to the pet's injury. The city's "no-pets-left-behind" policy results from the great number of pet deaths during the destruction of Hurricane Katrina. As emergency responders arrived to rescue people isolated in their homes during Katrina, hurricane victims were told that they could not take their pets along with them when evacuating; thus, many pet owners were forced to make the heart-breaking decision to save themselves while leaving their pets behind to perhaps meet their deaths. Since then, the U.S. has passed the Pets Evacuation and Transportation Standards Act of 2006, allocating federal funds for animal disaster planning projects. Yet, not all counties are as progressive as San Francisco has been in the effort to protect pets in the event of a natural disaster. Pets are after all, a large part of San Francisco's population -- overnumbering the number of school age children in the city. Over the last three years, San Francisco has received $350,000 in federal funds _ to animal disaster preparedness efforts in order to protect animals in the case of a disaster such as an earthquake. The city is still working on obtaining $300,000 to pay for an emergency animal unit. Until then, animal lovers in San Francisco will continue to work to ensure that pets are never an afterthought when it comes to rescues during earthquakes or... Question: What do we know about Hurricane Katrina? Yes or no, is the answer "A great number of pets died during Hurricane Katrina."?
