Read the following article and select the best answer. Article: BEIJING - Astronomers have defended against rumors that the terrible earthquake and the following tsunami in Japan were closely related to or even caused by the "supermoon" that will appear in the sky on Saturday. The word "supermoon" was introduced in a report by the British newspaper Daily Mail on March 9, which said amateur scientists were warning that such an astronomical phenomenon could disturb the Earth's climate patterns and may even cause earthquakes and volcanic activity. The moon will be 356,577 kilometers from the Earth on Saturday, the closest in 19 years, and the closest point in its oval orbit coincides with a full moon, the report said. However, Saturday's moon is not actually the closest to Earth in 19 years, Tang Haiming, an astronomer with Shanghai Astronomical Observatory under the Chinese Academy of Sciences, told Xinhua News Agency. A shorter distance of 356,570 km between the two bodies was reached in January 2005, and a distance of 356,566 km was seen in December 2008. Yet some people suggest that previous supermoons have occurred prior to extreme weather events. In 1974 the phenomenon was followed by Cyclone Tracy in Darwin, Australia, and in 2005 it occurred shortly before a deadly tsunami in Indonesia. Coincidentally, two fresh disasters happened in Asia right before Saturday's supermoon. The public's concern about their connection with the moon boomed after Japan's terrible earthquake and tsunami and an earthquake in Southwest China's Yunnan province that killed 25 people on March 10. But astronomers are trying to _ people that such rumors are merely unreasonable. "A supermoon could cause high tides but has no direct relation with natural disasters such as earthquakes," Liu Jie, a researcher with the China Earthquake Network Center, told China Daily on Tuesday. "We can't find any necessary connection between previous supermoons and earthquakes. And the quake in Japan occurred because the Earth's inner energy had accumulated to some extent, and it's not related to the moon. "...

Read the following article and select the best answer. Article: It could happen just about any time you step out in public. You get onto an almost-empty bus, but the next passenger in decides to ignore dozens of empty seats to sit right next to you. While you're waiting in line at a supermarket, the next customer insists on standing only two inches behind you and shouting into his cell-phone. You go into a public restroom, and the next person to enter decides to use the next stall. Transgressions like these don't just make us feel uncomfortable; we often feel anxious, alarmed; and violated . It is the attack of the personal-space invaders. In any society, shared definitions of personal space govern how we interact with other people. People living in densely populated cities like Mumbai, Beijing, or Mexico City tend to require less personal space than people living in sparsely populated places within the country. In America, New Yorkers often have smaller requirements than residents of western states, like Montana, Shenandoah and Wyoming. Because everyone has different standards, gestures that are innocent in one place can be interpreted as opposite in another, especially in Britain. As the British etiquette website Debrett puts it, as a British person, somebody standing too close may make you "focus less on what somebody is saying than on how close they are to you". Simple acts like putting an arm around someone you don't know may seem friendly in China, but they can make us very uncomfortable. People from many European countries such as France and Spain kiss each other on the cheek when they meet, yet to British person, this seems too friendly and "touch-freely". The website explains! "The British are not backslappers and generally do not show affection in public". Are British people unfriendly? Far from it. The website adds that they are not as " _ ' as they may seem, but very friendly and helpful to foreigners. However, remember not to be too close. If you are going to come closer than an arm's length, please let them know. Question: What can we conclude from the article? - British people like to sit next to other people on empty buses. - British people usually kiss strangers on the cheek to greet them. - British people are helpful though they may not appear to be. - British people are delighted to show affection in public.
British people are helpful though they may not appear to be.
