单选题The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who can't hear the instructions to turn off his radio because the music's too loud.

单选题The International Olympic Committee (IOC) has launched an investigation into allegations that its officials in more than 50 countries have been selling London Olympics tickets on the black market for profit. The IOC met at an emergency session on Saturday to look into a pile of evidence uncovered by Britain"s Sunday Times newspaper. The paper claims that high-ranking Olympic officials have been selling tickets for the games at hugely inflated prices. The highest priced tickets on the black market were for the men"s 100- meter final. The IOC has issued a statement saying it "takes these allegations very seriously and has immediately taken the first steps to investigate." IOC rules forbid national Olympics committees from selling tickets overseas, increasing ticket prices or selling tickets to unauthorized, third-party resellers. Despite this, Sunday Times undercover reporters posing as illegal ticket sellers say they have recorded evidence of 27 officials selling tickets distributed to 54 countries. One of the most serious allegations was against the Greek Olympic Committee president Spyros Capralos. He denies saying he had "pulled strings" with the head of the London Olympics Sebastian Coe even though the paper posted videos of its reporters" negotiations with Capralos on its website. Mr Capralos has so far refused to comment.
