Article: It is sometimes said that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report. Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night. "It wasn't the moon," was the reply. They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn't smoke because it didn't change its shape. It was moving in a regular way. That is to say, it didn't go suddenly faster or more slowly, and it didn't go higher or lower. So the two men decided that there must be men in it. After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness. When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast. On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken? Question: A UFO was seen one night _ . Yes or no, is the answer "when they were walking across a yard to Burdens' room"?
(Answer)
Yes

Ques: Article: Removing the sleeve , you will find a book that is entirely white, except for the names of its author and subject in elegant black type on the cover. It is the perfect design for the biography of a man who insisted that even the insides of his products be perfectly constructed, and that his factory wails flash in the whitest white. The cover was the only part of the book Steve Jobs wanted to control, writes Isaacson in his introduction. Though Mr. Jobs pushed the biographer of Albert Einstein and Benjamin Franklin to write in his own way, generously allowing the writer more than 40 interviews, this book offers quite a different view of Mr. Jobs, who won much praise from his fans after his death on October 5th at the age of 56. As a biographer of Albert Einstein and Benjamin Franklin, Mr. Isaacson knows how to celebrate long-dead genius, but he claimed that "Steve Jobs" would not be entirely praiseful words. The picture he paints, particularly in the first half of this book, is not nice. Mr. Jobs emerges as a controlling and often cold-blooded character. A child of the 1960s counter-culture , he hated, materialism and lived in simply furnished houses ( in part because he was too particular about furniture). But when Apple went public in 1980, he refused to give any share to Daniel Kottke, a Iongtime supporter and soul mate from college. "He has to abandon the people he is close to," observes Andy Hertzfeld, an early Apple engineer. Mr. Jobs was undoubtedly possessing an extraordinary ability to attract others and inspire a kind of faith that could not be questioned. But also he could be cold and cruel. If he disapproved of an employee's work, he often shamed him. "This is who I am," he once said after being challenged,"and you can't expect me to be someone I'm not. " This disgusting personality wasn't always helpful,but it served a purpose, writes Mr. Isaacson, many would "end their chain of horror stories by saying that he got them to do things they never dreamed possible. " Mr. Isaacson treats "Steve Jobs"... Question: This passage can be classified as _ Yes or no, is the answer "a book review"?
Ans: Yes

Article: A California man who was feeling sick almost died recently from a shocking cause. 26-year-old Luis Ortiz went to a hospital because of a headache and nausea(,). When doctors examined him, they were shocked to find a tapeworm larva in his brain. The story gets stranger. The larva was still alive. The creature had caused a cyst to form inside his head. The cyst was restricting the flow of liquids to different areas of his brain. The situation was so serious that doctors said they had to perform an emergency operation to remove the larva. A doctor who operated on Ortiz told him he had only 30 minutes to live. When the doctor pulled the worm out of his head, it was still moving. Luis Ortiz was a student at California State University in Sacramento. He began experiencing headaches in late August. But Ortiz said he did not think the headaches were serious. In September, he visited a friend and his parents in another city. That is when the pain got worse. His mother saw Ortiz throwing up and took him to a hospital emergency room. The doctors saved Ortiz's life. However, the surgery also affected him. Ortiz had to drop out of school and move back home. For now, he is not permitted to work or drive a vehicle. The U.S. Centers for Disease Control and Prevention says the U.S. has about 1,000 reported cases of tapeworms each year. The CDC adds that tapeworms are more common in developing countries with poor public health systems. The best way to avoid a tapeworm infection is to wash fruits and vegetables. Also, make sure meat is cooked thoroughly. The CDC suggests cooking all meats to an internal temperature of at least 63 degrees Celsius. Question: If the doctors didn't have an emergency operation on him , Luis Ortiz was likely to _ . Yes or no, is the answer "live for only half an hour"?
No
