Example Input: Article: Ocean Park If you love the sea, Ocean Park is the place for you! Situated on the south side of Hong Kong Island, this 870,000 square metre educational theme park provides many opportunities to learn about marine life. To start with, the park boasts the Atoll Reef, one of the world's largest aquariums, with about 2,500 fish from nearly 300 different species. What makes this aquarium special, however, is not just its size, but also its design. The Atoll Reef is built with an observation passageway that circles the aquarium on four different levels. This lets visitors view sea life from a variety of depths and angles. Then there's the Shark Aquarium, a tank with more than 200 sharks from more than 30 species. Like the Atoll Reef, this unique aquarium is designed to make sure guests get the most out of their visit. Shaped like an underwater tunnel, guests can watch as sharks swim overhead and dive at them from every side. There's also the Sea Jelly Spectacular, an aquarium that houses more than 1,000 jellyfish of all shapes, colours and sizes. And at the park's Dolphin University, visitors can go on educational tours and watch the training of dolphins up close. The park's most popular attraction is the Ocean Theatre, a huge outdoor pool where dolphins and sea lions entertain the visitors. Sometimes a killer whale even takes part in the performance! Although Ocean Parks focus is on the water, the theme park has plenty of other activities, too. For people seeking excitement, there are rides like the Abyss Turbo Drop, a roller coaster ride that takes passengers on a 20-storey drop straight down. There are also exhibits like the Dinosaur Discovery Trail and Bird Paradise. Finally, no trip to Ocean Park would be complete without visiting the park's most popular animals--four giant pandas that were given as a gift from China's central government.

Example Input: Article: When the US started the war in Iraq a year ago, Spain was a firm supporter. But on April 18, the Spanish government started to remove its troops, becoming the first country in the US-led coalition to bring its soldiers home. The person behind this surprise move is the new Spanish prime minister, Jose Luis Rodriguez Zapatero. A few months ago, he was hardly known outside his small hometown in northern Spain. Even a week before last month's general election, Zapatero was still considered an outsider for the top job. But just three days before the vote, a series of bomb attacks on three train stations in Madrid killed 191 people and injured some 1,900. It was Spain's worst ever terrorist attack and it changed everything -- even making Zapatero prime minister. From the beginning, the 43-year-old former lawyer, knew the weaknesses of Prime Minister Jose Maria Aznar and his hand-picked successor, Mariano Rajoy. About 90 per cent of the Spanish people were against the war in Iraq and were unhappy that Aznar had taken them into it. So Zapatero promised: "If this party wins the election and the UN still can't take charge in Iraq, the new government will pull its 1,400 troops out of Iraq." Despite focusing on this and other Aznar mistakes, Zapatero's chances of victory were still thin until the Madrid bombings. At first, the government blamed ETA, a separatist terror group from the Basque region of northern Spain. But later evidence suggested the attack was carried out by al-Qaida members angry at Spain's presence in Iraq. The people were upset, and they showed this by voting for Zapatero. Many accused the government of covering up information about the bombings and only blaming ETA so it wouldn't lose to an anti-war vote. In a move that was as shocking to the world as his election victory, Zapatero chose to carry out his promise the day after he took office. And its effect could be long-lasting. As the situation in Iraq worsens, several countries are considering their positions. The US is worried that other coalition members might follow Spain's lead and also bring their soldiers home.
Question: Why did the Spanish government try to hide the truth from the public at first?
Options: (A) They feared the terrorists would escape. (B) They were not quite sure who on earth made the attacks. (C) They were worried that they would lose the coming election. (D) They attempted to get rid of all ETA members.
Example Output: C

Example Input: Article: Expressions about water are almost as common as water itself. The expressionto be in hot water is a very old expression. Hot water was used five hundred years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle. That no longer happens. But we still get in hot water. When we are in hot water, we are in trouble. It can be any kind of trouble--serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother, if he walks in the house with dirty shoes. Beingin deep wateris almost the same as being in hot water. When you are in deep water, you are in a difficult position. To keep your head above wateris a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job. Water over the dam is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again. Another common expression to hold water, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container.; If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes. Throwing cold water also is an expression that deals with ideas or suggestions. It means to not like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea, because she says a new car costs too much.
