13．Does the Yangtze River still have baiji（白鳍豚），the graceful，grey dolphin with tiny eyes and a long narrow beak？
Since November 6，a team of scientists from China，Switzerland，the United Kingdom，the United States，Germany and Japan had been searching for any sign of the freshwater dolphin in the middle and lower sections of the river．After six weeks，they came back empty-handed．Wang Ding，head of the team，said he had seen a sharp drop in the baiji population over the past few decades．However，he was still unwilling to call the species extinct and added，"We will try every effort to save them as long as they are not found to be extinct．"
As one of the world's oldest dolphin species，the baiji is shy and nearly blind．It dates back about 20 million years and is found only in the Yangtze River．It's listed as one of the 12 most endangered animal species in the world．
Around 400 baiji were believed to be living in the Yangtze until the 1 980s．In 1997，a survey spotted 13．Two years later their number was down to zero．
The rapi d disappearance of this dolphin over the past two decades coincided（巧合） with the rapid expansion of economic development along the river．Resea rchers on some dead baiji collected in recent years showed that more than 90 percent of the deaths were caused by human activities．
One reason is that over-fishing has cut the dolphin's food sources．Dams built along the river and neighbouring waterways have also kept them from swimming into and out of their habitats．Meanwhile，waste discharge（排放） has seriously polluted the river．And heavy river traffic has greatly reduced their living space．
The disappearance of the baiji would be the first case of a large aquatic（水生的） mammal being driven to extinction since hunting killed off the monk seal around 1952．

44．We can infer from the passage thatA．

B．Baiji is one of the world's oldest species and lives longer than humans
C．it is the waste discharge that has poisoned Baiji in Yangtze River
D．nowadays scientists are no longer able to save Baiji at all
