Question: Write a multi-choice question for the following article: Article: At 2 p.m. on December 5, 1945, five Navy aircraft took off in perfect flying weather from a naval air installation in southeastern Florida, on a routine training mission over the Atlantic Ocean. Less than two hours later, the flight commander radioed that he was "completely lost". Then there was silence. A rescue plane was sent to search for the missing aircraft, and it, too, disappeared. Despite one of history's most extensive search efforts, involving more than 300 planes and dozens of ships, the Navy found nothing, not even an oil stain floating on the water. This is just one of the many frightening stories told of "the Bermuda Triangle", a mysterious area of the Atlantic Ocean roughly stretching southwest from Bermuda to the Florida coast and down to Puerto Rico. During the past 30 years, the triangle has claimed the lives of some 1,000 sailors and pilots. Stranger yet are the numerous "ghost" ships that have been found floating crewless within the triangle.

The captain of theEllen Austininstalled a new crew to sail it, but two days later, during a rough storm, the two ships temporarily lost sight of each other. When the captain again boarded the boat, he found his crew had disappeared. After a second crew was assigned, the ship was again lost in a fog bank. This time, no trace of the boat -- or the crew -- was ever found. Charles Berlitz, a man with an interest in Atlantis, the legendary lost island, puts forward his theory that a giant solar crystal, which once was the power generator for Atlantis, lies on the ocean floor. From time to time, according to his theory, passing ships and planes set off the crystal, which confuses their instruments and _ them into the ocean. Officially, the U.S. Navy does not recognize the triangle as a danger zone and is convinced that "the majority of disappearances in the triangle can be due to the...

[Q]: Write a multi-choice question for the following article: Article: Recently a Beijing father sent in a question at an Interact forum asking what "PK" meant. "My family has been watching the 'Super Girl' singing competition TV program.My little daughter asked me what 'PK' meant,but I had no idea,"explained the puzzled father. To a lot of Chinese young people who have been playing games online,it is impossible not to know this term.In such Internet games,"PK" is short for "Player Kill",in which two players fight until one ends the life of the other. In the case of the "Super Girl" singing competition."PK" was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking. Like this father,Chinese teachers at high schools have also been finding their students' compositions using Internet which are difficult to understand.A high school teacher from Tianjin asked her students to write compositions with simple language,but they came up with a lot of Internet jargons that she didn't understand. "My 'GG' came back this summer from college.He told me I've grown up to be a 'PLMM'.I loved to 'FB' with him together;he always took me to the 'KPM',"went one composition. "GG" means Ge Ge(Chinese pinyin for brother)."PLMM" refers to Piao Liang Mei Mei (beautiful girl)."FB" means Fu Bai (corruption)."KPM" is short for KFC.Pizza Hut and McDonald's. Some specialists welcome Internet jargons as a new development in language.
