Article: The Carnival of Brazil is an annual festival held 46 days before Easter, especially famous for the Carnival in Rio de Janeiro. Carnival celebrations are believed to have roots in the festival of Saturnalia, which, adapted to Christianity, became a farewell to bad things in a season of religious discipline to regret and prepare for Christ's death and coming back to life. Modern Brazilian Carnival dates back to Rio de Janeiro in 1641. It originally copied the European form of the festival, later taking in elements of Native American and African cultures. In the late 19th century, the strings were introduced in Rio de Janeiro. These were pageant groups that paraded through city avenues performing on instruments and dancing. Today they are known as blocks, consisting of a group of people who dress in costumes or special T-shirts with themes or logos. Blocks are generally connected with particular neighborhoods; they include both a music group and a lot of revelers. Block parades have become an expressive feature of Rio's Carnival. Today, they number more than 100 and the groups increase each year. Blocks can be formed by small or large groups of revelers with a clear title. Before the show, they gather in a square, then parade in sections of the city, often near the beach. Carnival time in Rio is very interesting, but is also the most expensive time to visit Rio. Hotel rooms and other lodgings can be up to four times more expensive than the regular rates. There are big crowds at some locations and life is far from ordinary in many parts of town. Question: What is the passage mainly about? Yes or no, is the answer "The carnival in Rio de Janeiro."?
Yes

Article: There was once an ant that was very thirsty. It ran here and there looking for some water but could not find any. Then suddenly, when the ant was almost ready to die of thirst, a large drop of water fell on it. The ant drank the water, which saved its life. The water was actually a tear from a young girl who was crying. Because of her sadness, the tear had magical qualities and suddenly the ant could speak the language of human beings. The ant looked up and saw the young girl sitting in front of a huge pile of seeds. "Why are you sad?" asked the ant. "I'm the prisoner of a giant." the girl told the ant. " He won't let me go until I've made three separate heaps of grain, barley and rye out of this huge pile of seeds in which they are all mixed together." "That will take you a month!" the ant said, looking at the huge pile of seeds. "I know," the girl cried, "and if I haven't finished by tomorrow, the giant will eat me for his supper!" "Don't cry," the ant said, "my friends and I will help you." Soon thousands of ants were at work, separating the three kinds of seeds. The next morning, when the giant saw that the work had been done, he let the girl go. Thus it was one of her tears that saved her life. Question: What is an ant? Yes or no, is the answer "An insect."?
No

Article: Thank you for agreeing to be a Test Administrator for PISA. The purpose of this manual is to help you to understand how you will assist with the successful implementation of this large-scale student survey. 1.1. What is PISA? PISA stands for the Programme for International Student Assessment, sponsored by the Organisation for Economic Co-operation and Development (OECD). PISA 2015 is the sixth PISA study that has been conducted since 2000 and involves more than 70 participating countries. PISA has the following characteristics: * It is the world's largest international survey in education. * It surveys students aged about 15 years. * It assesses students' preparedness for adult life. Undertaking PISA is important because the results of the test can be used: * to indicate how well prepared students in a country/economy are for learning once they leave school; * to identify areas for improvement over time by schools, education systems, and governments; and * to allow a comparison of student performance and the learning environment between different countries. 1.2. Components of PISA 2015 * 1.2.1. Cognitive test 42 students from each school will be randomly sampled to complete a 2-hour computer-based test consisting of questions in science, mathematics, reading, and Collaborative Problem Solving. * 1.2.2. Questionnaires These students will also be asked to complete a 30 minutes Student Questionnaire on the computer either directly after the test sections or at a later time. * 1.2.3. Financial Literacy assessment After the cognitive test and questionnaires, a sub-sample of 10-11 students will take a computer-based Financial Literacy(FL) assessment. The 65-minute Financial Literacy assessment tests students' knowledge of personal finances and their ability to apply it to their financial problems. Question: According to the manual, each participating student of PISA should _ . Yes or no, is the answer "carry out all the tasks on the computer"?
No

Article: When it's 10:15 in New York, it's 9:15 in Salt Lake City, and 7:15 in San Francisco - isn't it? This consistent and orderly time system, based on a grid of time zones, seems so natural that people rarely give it a moment's thought. So you may find it surprising to learn that prior to the late 1800s each community established its own time - by looking at the sun. When the sun shone directly overhead in Washington, D.C., for example, it was 12:00 noon there; up the road in Philadelphia, however, it was 12:07, and in Boston it was 12:24. To measure time with accuracy, it is necessary to move the clock about one minute for every twelve miles of distance; so according to "sun time" your pocket watch would be slightly incorrect if you ventured only a few miles down the road. It was not until the advent of widespread railroad travel that a need arose for regularized time. At one point over 300 local times were honored within the country, making it literally impossible for trains to arrive consistently on time everywhere. As a result, in 1883 the continental, United States was divided into four time longitude. The standardization resulting from this system proved so helpful that in 1884 the International Meridian Conference applied the same procedure to establish time zones around the world. Thus, if it is 11:07 p.m. in Tuscaloosa, Alabama, a little simple research will quickly determine that in Kuala Lumpur, Malaysia, it is 9:07 A.M. - and not 9:15. Question: The cause of the regularized time is_. Yes or no, is the answer "the widespread railroad travel"?
No
