Input: Consider Input: Article: Who Owns the Moon? Within the next ten years, the U. S., China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does _ give them property rights? A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international signed by more than 100 countries, states that the moon and other celestial bodies are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs. But ownership is different from property rights. People who rent apartments, for example, don't own where they live, but they still hold rights. So with all of the upcoming missions to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush. " This is a very relevant discussion right now. We've got this wave of new lunar missions from around the world," said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA's Co Lab, a collaborative public-private working group. He was speaking from his personal interest and not on behalf of the agency. To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission.
Answer: no one can answer the question " Who owns the moon?"

Output: In the passage the writer seems to be worrying that _ .

Input: Consider Input: Article: The British Museum first opened in the 18th Century largely based on the collections of the scientist Sir Hans Sloane. The current neoclassical building was founded nearly a century later and is quadrangular with four wings and a great classical appearance. Inside is a courtyard, the Great Court, covered with a special modern addition--a spiraling glass and steel roof which was designed by Norman Foster and completed in 2000. The courtyard surrounds the round Reading Room with a copper domed ceiling the same size as the dome of St Peter's in Rome. The museum, one of the oldest in the world, is Britain's largest museum, and widely considered to be one of the world's greatest museums of human history and culture. The permanent collection is made up of over 8 million objects spanning the history of the world's cultures from the stone tools of early man to twentieth-century prints. The collection includes controversial items including the Elgin Marbles from the Parthenon in Greece, Egyptian mummies and the Rosetta Stone. The expansion of the museum over the years has resulted in the creation of several branch institutions including the Natural History Museum in South Kensington. The British Library previously occupied the Reading Room but in 1997 moved to a new site next to St Pancras Station on Euston Road. There are frequent special exhibitions of international significance. Opening Times: The museum is open daily from 10:00 am to 5:30 pm. On Fridays it stays open until 8:30 pm. Entry to the museum is free, although a charge may be made for entry to temporary exhibitions. Address: Great Russell Street, London WC1B 3DG. Nearest Underground Station: Tottenham Court Road (5-minute walk), Russell Square (6-minute walk) and Holborn (7-minute walk).Website: http://www. britishmuseum. org/.

Input: Consider Input: Article: Imagine a stranger walking past you on a cold, rainy day. "Lovely weather, isn't it?" the stranger says. Do you laugh, or even smile? If not, you may not have a dry sense of humor. British people, and particularly the English, are well-known for our dry sense of humor. We often say the opposite of what we mean in order to be funny, and tell jokes in a tone of voice that makes it sound like we are being completely serious. As US writer Julian Tan put it on the HuffPost Students blog: "It is as if it is 'Opposite Day' every day in Britain." If the people of Britain are known for having a " _ " and not showing emotion, then our dry sense of humor shows this through jokes. Often it will take a long time or several beers, to get a British person to tell you what they actually think about something and get behind the wall of humorous sarcasm that they have in front of them. English comedian Ricky Gervais put it like this: "We play jokes on our friends. We use sarcasm as a shield and a weapon. We avoid being serious until it's absolutely necessary." It can be annoying and confusing if you haven't been raised with these types of jokes: "Why did he just say such a ridiculous thing? Is he making fun of me?" But it is also true that understanding this type of humor is a good way to make friends with people in the UK, even if you don't find it funny. It's important to remember that the person telling the joke may actually be making fun of himself or herself, not you. One of the characteristics of British humor is "its strong theme of self-deprecation" (making fun of oneself), according to Tan. So don't worry - often, English people, and British people in general, just want to make fun of themselves!
Answer: not use sarcasm as a shield and a weapon.
Output: According to the passage, we can know that someone with a dry sense of humor can _ .
