Read the following article and select the best answer. Article: Researchers have found a village that may have been home to the builders of Stonehenge. The village of small houses dates back to about 2600 BC. That's about the same time Stonehenge was built. "Clearly, this is a place that was of great importance," said researcher Mike Parker Pearson. The ancient houses are at a site known as Durrington Walls. It is about 3.2 kilometers from Stonehenge. Researchers believe Stonehenge was a memorial site or cemetery for the villagers. The village also had a wooden version of the stone circle. It may have been used by people attending festivals at Stonehenge. Eight of the houses have been dug up. Researchers say there may be as many as 25 of them. The wooden houses were square and about 5 meters along each side. There are signs that there were beds along the walls. There are also signs of a storage unit. The houses also had fireplaces. Two of the houses were separate from the others. They may have been the homes of community leaders. Researchers say those didn't have the household rubbish that was found in the other homes. Stone tools, animal bones, arrowheads and other things were found throughout the village site. Stonehenge is a popular tourist spot in England. It is a huge circle made out of stones, which were placed in a grass field in southern England. The stone arches were made with two stones at the bottom and one across the top. All of the stones weigh a lot more than a big car. Scientists have long wondered not only how people built Stonehenge, but also why. Question: The passage is mainly about _ . - researchers working at Stonehenge - a village site near Stonehenge - the wooden version of Stonehenge - builders of Stonehenge and the houses
a village site near Stonehenge

(Question)
Read the following article and select the best answer. Article: When was the last time you laughed a lot? Most people are the victim of an uncontrollable fit of laughter at least once in their lives. But when it happens in front of the television cameras, it can become an internet sensation. Do you think there's anything funny about spicy meat? Swiss finance minister Hans-Rudolf Merz seemed to think it was hilarious. Mr. Merz was making a speech in the Swiss parliament on meat imports when he started laughing and couldn't stop. The meat in question is known as "bundnerfleisch"-- a type of air-dried beef product. Herr Merz later admitted that he was amused by the bureaucratic language in which the bill was written. Since then, Mr. Merz has become an internet hit. A video of the incident shows a grey-suited minister giggling away, accompanied by applause from his parliamentary colleagues. So far, the video has been seen by more than 500,000 people on YouYube and other websites. "I don't understand what he's talking about," said one viewer, "but it's just so funny." The recent publicity will be good news for the minister, too. Mr. Merz had been criticized recently for signing away much of Switzerland's banking secrecy, and for failing to do enough to help two Swiss citizens who were detained by Libya. But now, with retirement a few months away, Mr. Merz may leave on a high note. Some even suggest he may have a future career as a comedian. Of course, Mr. Merz isn't the first person to _ on air. BBC Radio 4 newsreader Charlotte Green lost control on the programmeTodaynot so long ago. It all happened after a clip of the oldest known recording of the human voice was played. A studio member remarked that the 1860 recording of a woman singing the French song "Au Clair de la Lune" sounded like a "bee buzzing in a bottle". That seemed to set Ms. Green off as she broke down into a fit of the giggles. Later, the editor of the show, Ceri Thomas, said most listeners who contacted the show had commented on "how much they had enjoyed the moment". He added, "When Charlotte loses it, she... Question: It can be inferred from the passage that _ .[ ] - uncontrollable fits of laughter is very common among people. - Mr. Merz will be a comedian after retirement. - Charlotte Green will be dismissed due to this incident. - most of the listeners who contacted the show thought it inappropriate for a newsreader to laugh away on the programme.
(Answer)
uncontrollable fits of laughter is very common among people.

Question: Read the following article and select the best answer. Article: After years of research and testing, the hybrid car was developed and put on the market. It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources. The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which are used to power a car's engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution. A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack is actually recharged( ) through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it generates electricity. Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically ( ; )shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up. Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas". When it completely runs out, the warning reads, "YOU ARE NOW OUT OF GAS!" Then the electric power supply kicks in to let the driver travel a few more miles to a gas station. Question: According to the passage, the word "hybrid" refers to _ . - a high tech discovery - energy saving - a new invention - a combination of two things
Answer:
a combination of two things
