[EX Q]: 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.
[EX A]: C

[EX Q]: Article: Ever wondered how one person could save the planet from the effects of climate change? A British-made computer game on trial release on Monday creates different ways of doing just that. "Fate of the World"puts the Earth's future in players' hands, placing them in charge of an international environmental body which could save the world from the effects of rising greenhouse gas emissions or let it destroyed by more emissions. Through different scenes, players can explore options such as geoengineering and alternative energy sources to save the planet from rising temperatures, decreasing natural resources and a growing population over the next 200 years. An improved version of the game will be followed by a three-month feedback period from players, with final release due in February next year. Created by Oxford-based games developer Red Redemption, the game is different from other mainstream action games mainly by using data from real climate models and advice from scientists and economists. "Science data is often inaccessible and we are trying to put players in a position of power and connected with the issues," Gobion Rowlands, Red Redemption's founder and chairman said. This year, a series of apparent errors in climate science and the failure of UN talks to reach an international deal to cut greenhouse gas emissions appeared to weaken the public's interest in climate change. However, games centered on sustainability and human rights have been growing in popularity and are welcomed by green groups as a way of raising awareness. Using climate change as inspiration for entertainment shows the issue has affected global culture, which can only be a good thing.Friends of the Earth's head of climate Mike Childs said."We need creative industries to work with these big issues as the results can be extremely powerful and can help us to understand what a sustainable future looks and feels like,"he added.
