Article: Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943. In 1967, Tasmania experienced a drought . The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989. Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals . For example, in 1992, Tasmania extended daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games. The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television. Question: Daylight Saving Time was introduced in Tasmania _ . Yes or no, is the answer "to save water and electricity"?
No

Article: Here is a question I have often asked at dinner parties: You're on an island with only one other person, your best friend. He's dying of cancer. In his final days, he tells you, "I have 100,000 dollars in a bank back home. When I die, make sure my son goes to medical school." Then he dies. But his son is a no-good playboy who has no interest in going to medical school and will waste that money away in a very short time. But your son is entering college, and he is willing to become a doctor. Which one do you give the money to for medical school? I've asked this question of everyone from the president of a famous university to an ordinary young soldier, and it has never failed to get a discussion going. Everyone has an opinion, most of them different, but all of them correct. Sometimes this one topic lasts the whole evening. Question: Why does the writer often ask people such a question? Because _ . Yes or no, is the answer "he wants to offer people a topic in which everyone could say something"?
Yes

Article: Scientists have long puzzled over how iguanas, a group of lizards mostly found in the Americas, came to live in the isolated Pacific islands of Fiji and Tonga. Some scientists used to suppose that they must have traveled there on a raft, a journey of around 5,000 miles from South America to the islands. There are documented cases of iguanas reaching remote Caribbean islands and the Galapagos Islands on floating logs. But new research in January by Brice Noonan and Jack Sites suggested that iguanas may have simply walked to Fiji and Tonga when the islands were still a part of an ancient southern supercontinent. The ancient supercontinent was made up of present-day Africa, Australia, Antarctica and parts of Asia. If that's the case, the island species would need to be very old. Using "molecular clock" analysis of living iguanas' DNA, Noonan and Sites found that, sure enough, _ has been around for more than 60 million years--easily old enough to have been in the area when the islands were still connected by land bridges to Asia or Australia. Fossils uncovered in Mongolia suggest that iguanid ancestors did once live in Asia. Though there's currently no fossil evidence of iguanas in Australia, that doesn't necessarily mean they were never there. "The fossil record of this continent is surprisingly poor and cannot be taken as evidence of true absence," the authors write. So if the iguanas simply walked to Fiji and Tonga from Asia or possibly Australia, why are they not also found on the rest of the Pacific islands? Noonan and Sites say fossil evidence suggests that iguana species did once inhabit other islands, but went extinct right around the time when humans settled in those islands. But Fiji and Tonga have a much shorter history of human presence, which may have helped the iguanas living there to escape extinction. The researchers say that their study can't completely rule out the rafting theory, but it does make the land bridge theory "far more reasonable than previously thought." Question: What did some scientists previously believe about the iguanas? Yes or no, is the answer "They traveled by raft to Fiji and Tonga."?
No
