Article: On a flight from Johannesburg, a middle-aged rich white South African lady had found herself sitting next to a black man. She called the cabin crew attendant over to complain about her seat. "What seems to be the problem, Madam?" asked the attendant. "Can't you see?" She said, "You have seated me next to a black person! I can't possibly sit next to this kind of person. Find me another seat!" "Please calm down, Madam," the stewardess replied. "The flight is very full today, but I will tell you what I will do---- I will go and check to see if we have any seats available in club or first class." The woman glanced at the angry black man beside her. A few minutes later, the stewardess returned with the good news, which she delivered to the lady. "Madam, unfortunately, as I expected, economy is full. I have spoken to the cabin services director, and club is also full. However, we do have one seat in first class." Before the lady had a chance to answer, the stewardess continued, "It is most extraordinary to make this kind of upgrade, however, and I have had to get special permission from the captain. But, learning this condition, the captain felt that it was shocking that someone should be forced to sit next to such a tiring person." Having said that, the stewardess turned to the black man sitting next to the lady, and said, "So if you'd like to get you things, sir, I have your seat ready for you..." At this point, obviously the surrounding passengers stood and gave an applause while the black man walked up to the front of the plane. Question: What was unexpected to the lady? Yes or no, is the answer "They found another seat for the black man."?
No

Article: The Beijing Hutong (old lane) areas have a very special and important position in the rich history and culture of Beijing. While visiting the Beijing Hutong, you can appreciate the dramatic changes that the rest of Beijing has undergone. You can see evidence of the history of Beijing, experience the old way of life and experience traditional Beijing culture. The Beijing Hutong is made up of lanes or alleys formed by lines of pre-modern quadrangles (siheyuan), four-sided dwelling compounds or quadrangles consist of one-story courtyard houses, which make up old Beijing, and feature typical Chinese residential architecture. Beijing road classification was once s follow: A 36-foot-wide road was called a standard, street, an 18-foot-wide one was a small street and a 9-foot-wide lane was named a hutong. In fact, the Beijing Hutongs are unclassifiable by the traditional standard, ranging from 40 centimeters to 10 feet in width. The longest hutong has more than 20 turns. It is easy to get lost in the maze of winding lanes hat is the hutong, with the gray-tiled houses and deep alleys crossing each other, all identical in appearance, with many blind hutongs or culdesacs. Hutongs were first named as such in the Yuan Dynasty(1271-1368), with its Mongolian rulers having an influence on the Chinese language. However, siheyuan or quadrangles have probably been around much longer. The name of a hutong represents its origin, location or history. It is in the gray-tiled deep lanes that families play, travel, buy goods, gossip and connect. In beijingers'eyes, hutong means a period of history, a cordial lifestyle and even an "encyclopedia of Beijing". When urban construction threatens the existence of these hutongs, Beijingers become worried. Beijing still has about 400 000 residential quadrangles now, mainly distribute over the East, West, Xuanwu and Chongwen districts. The municipal government has marked a number of these compounds for protection. If you would like to have a glimpse into Beijing' Yesterday, you are... Question: Where can this passage be found?

Ques: Article: Research suggests that a newly-identified gene known as insomniacs may play a role in keeping us asleep. By cloning and testing this gene in about 21,000 fruit flies, Rockefeller University researchers say they have discovered an entirely new mechanism by which sleep is controlled. By studying these flies, the researchers discovered that mutations in the insomniac gene were associated with a great reduction in sleep. While a typical fruit fly slept for an average of 927 minutes a day, the mutant flies slept for just 317. They also slept for shorter periods of time, and slept and woke more frequently. "The results showed a great loss of both the time that the flies' sleep lasted and their ability to remain asleep after they slept," says researcher Nicholas Stavropoulos. The researchers also examined the link between sleep and lifespan, finding that flies with mutations to the insomniac gene lived only about two-thirds as long as unchanged flies. But when the scientists removed insomniac only inneurons ---allowing it to remain in the rest of the flies' bodies---this difference disappeared; the resulting animals slept poorly but lived just as long. "This suggests that reduced sleep can be 'uncoupled' from reduced lifespan, supporting the idea that some interruptions of sleep do not affect overall health, at least as far as lifespan is concerned," Stavropoulos says. Although flies and humans would appear to have little in common when it comes to lifestyle, scientists say that the mechanisms of sleep and wakefulness are likely to be quite similar. "Sleep is a fundamental behavior in all animals, and it is poorly understood from a scientific standpoint, says Stavropoulos. This work could prove useful in understanding and treating sleep disorders" Question: The text is mainly about _ . Yes or no, is the answer "the influence of a gene on the ability to sleep"?
Ans: No
