TEXT A1 MOSCOW, Russia (Reuters)-The personal fortunes of Russia’s 100 richest businessmen are as big as a quarter of the nation’s entire economy, business journal Forbes says.2 "Capital in Russia is not only concentrated in the hands of a small group of people, but also associated with just one city," Forbes said in a press release ahead of publishing a list of Russia’s 100 wealthiest.3 "No other city in the world can boast such a large number of billionaires as Moscow."4 Russia’s biggest billionaire Mikhail Khodorkovsky, the main shareholder in oil company YUKOS, will find it hard to enjoy his fiches, although he too is in the Russian capital.5 Khodorkovsky is worth $15.2 billion, but is languishing in a Moscow jail awaiting trial for fraud and tax evasion.6 The charges against Khodorkovsky are widely seen as part of a Kremlin campaign to destroy the politically ambitious magnate’s influence.7 His arrest has found wide support in Russia, the world’s second largest oil exporter, where the vast majority of people have gained little from the privatisations of the early 1990s.8 "By contrast, the combined net worth of all American billionaires is equivalent to just six percent of the gross domestic product of USA," said Forbes.9 In this year’s Forbes full list of the world’s billionaires published in February, Khodorkovsky was followed among Russians by Roman Abramovich, the owner of English premier league football club Chelsea. Abramovich’s wealth was valued at $10.6 billion.10 On the Forbes list published on February, the other names making up the Russian top 10 were Mikhail Fridman on $5.6 billion, Vladimir Potanin on $4.9 billion, Mikhail Prokhorov on $4.8 billion, Vladimir Lisin on $3/8 billion, Alexei Mordashov on $3.5 billion, Oleg Deripaska and Viktor Vekselberg, both on $3.3 billion, and Vagit Alekperov on $2.7 billion. Which of the following can NOT be inferred from the news
TEXT B1 GAZA CITY (CNN Thursday, May 13, 2004 Posted: 8:35 AM EDT (1235 GMT))-Two Israeli helicopter attacks Thursday in Gaza’s Rafah refugee camp have killed 10 people, according to Palestinian security and medical sources.2 The strikes followed Palestinian attacks on Israeli soldiers Tuesday and Wednesday that have claimed 11 soldiers’ lives. This week, violence in Gaza has claimed the lives at least 33 Palestinians as well as the 11 soldiers.3 The fighting comes as Israeli Prime Minister Ariel Sharon works on revising his plan to withdraw military personnel and Jewish settlements from Gaza and parts of the West Bank.4 Israel Defense Forces began the Gaza operation Monday night, saying the mission was aimed at destroying workshops used by Palestinian terrorists to construct Qassam rockets.5 Israeli helicopters first attacked the camp early in the day, killing seven and wounding six others, Palestinian security sources and medical sources said. A second strike was launched around 10:30 a.m. (3:30 a.m. ET), killing three and wounding eight others, the sources said.6 Wednesday night, an Israeli missile strike in Rafah killed seven Palestinians, Palestinian medical sources said. Israel Defense Forces said the Palestinians were targeted because they were trying to hide an explosive device. The strikes on the camp followed an attack that killed five Israeli soldiers traveling in a convoy near Rafah, according to the IDF.Note:7 Sharon’s withdrawal proposal - which would unilaterally withdraw Israeli military and settlements from Gaza and some regions, but not all, of the West Bank-has been praised by President Bush but was voted down in a Likud party referendum May 2.8 The prime minister has said the withdrawal is necessary because the Palestinian Authority had failed to rein in attacks on Israelis and because the diplomatic process is in a "frozen state."9 Palestinians have criticized Israel’s new plan, charging Sharon is attempting to circumvent the negotiations called for in the road map to Middle East peace, which is supported by the United States, the United Nations, the European Union and Russia. The word ’circumvent’ in the last paragraph is closest in meaning to which of the following
