Read the following article and select the best answer. Article: The royal family is a part of British history and cultural identity. Up until the 17th century, people believed that the British king or queen had a "divine right" to rule. This was the idea that God chose the king or queen and that he or she was therefore above the law. However, this idea was challenged during the English Civil War, when King Charles the First was put in prison and then killed in 1649. So what role does the British royal family have today? The Queen is head of the UK and the Commonwealth. She has important formal duties that go with her different titles. As Head of State, for example, she represents the UK on visits abroad and invites other world leaders to visit the UK;as Head of the Armed Forces in name, only she can declare when the UK is at war or when a war is over. She has to sign many government and Commonwealth documents every day. Although the royal family does the work for the UK, there are British people called"anti-monarchists "who do not believe there should be a royal family. One criticism is that the British people should not have to pay for the royal family with their taxes . Today, the royal family works hard to be relevant in the modern world. The Queen still gives a speech to the nation on television at Christmas, but it gets less and less formal every year;now it is even available as a podcast . In 2005, after graduating from university, Prince William spent time teaching English in Uruguay, the sort of work many ordinary young British people do in their gap years. Question: Which of the following is among the formal duties of the Queen? - Traveling around the UK. - Declaring when the world is at war. - Inviting other leaders to have dinner with her. - Signing Commonwealth documents every day.
Signing Commonwealth documents every day.

In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that. Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere. A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy. Boaz Leupe, CEO of the start-up Nerdalize, says it's actually quite simple."We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe. The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center," says Leupe. One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server's processors so it cannot be used as the primary source. But he is ready to try it. "If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills." Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in...

Read the following article and select the best answer. Article: This is the age of being busy. Many of us live in busy places and have busy lives. Even the roads are busy as we try to get from here to there. Adults are busy going to jobs and taking care of their families. Kids are busy, too, going to school and doing a lot of homework after school and on weekends. Busy isn't bad, necessarily. If you are not busy enough you might be bored. But if you are too busy, you might break down. For example, if you have a soccer game that runs late on a school night and you haven't eaten dinner or done your homework, that's a not-so-fun kind of busy. We wanted to know what kids thought, so we did a kidsPoll about being busy with 882girls and boys aged 9 to 13. Almost all of them said they felt stressed because they were too busy. About half said they felt this way once in a while or some of the time. But 17% said they felt this way most of the time and 24% said they felt this all the time! Oh dear, that's no fun. Only 4% of kids said they wanted less free time and 18% said they already had just the right amount. But, no big surprise, 61% of kids wish they had a lot more free time. If they had more time, most would spend it hanging out or playing with friends. Often, adults plan large parts of a kid 's day, especially during the school year. kids can't tell their parents they'll be skipping school today to get more free time! But they can tell their parents they'd like to play a game or read a book during their free time instead of watching TV. Question: By giving the example of a late soccer game, the writer intends to tell us _ . - Being too busy is bad for the kids - It is no fun to be busy for the kids - Homework should go before gam. - Being busy may cause the kids to feel bored
(Answer)
It is no fun to be busy for the kids
