Read the article and select the best answer. Article: Do you want to live another 100 years or more? Some experts say that scientific progress will one day help humans to last tens of years longer than what is now seen as the natural limit of the human life span . " I think _ ," said Michael Zey, a Montclair State University business professor and author of two books on the future. " I think by 2075 we will see it and that's a conservative estimate ." At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said progress in using genes as well as nanotechnology makes it likely that humans will live in the future beyond what has been possible in the past. " There is a great push so that people can live from 120 to 180 years," he said. " Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years." However, many scientists who research into aging are doubtful about _ and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death. Scientists also disagree on what kind of life the super aged might live. "It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120." said Leonard Poon, director of the University of Georgia Gerontology Center. " At present people who could get to that point are not in good health at all." Question: By saying " we are knocking at the door immortality", Michael Zey means _ . Options: A: they believe that there is no limit of living B: they are sure to find the truth about long living C: they have got some ideas about long living D: they are able to make people live beyond the present life span

Read the article and select the best answer. Article: One evening last fall, while Marcos Ugarte did his homework and his father, Eduardo, a teacher, prepared lesson plans, they heard shouting outside. Eduardo, 47, and Marcos, 15, stepped onto the balcony of their two-story home. Immediately, Marcos' s eye was caught by a flame from one of their neighbors' houses. "Dad, the house is on fire!" Marcos cried. Dressed only in shorts, the barefoot teen dashed towards the Mas' home with his dad. Grandmother Yim Ma, mother Suzanne Ma, and son Nathan Ma were gathered on the front grassland shouting for help. When the Ugartes got there, they saw through the open front door that father Alex Ma was falling down the stairs, coughing, his face black with dirt. "Is anyone else in the house?" Eduardo asked. "My son!" Alex managed to say, pointing to the second floor. Eduardo started up the stairs, but thick, black smoke, swirling ash, and extreme heatforced him to his knees. He inched upstairs and down the hall where Alex said he would find Cody, eight, who had locked himself in a bedroom. "I'd never seen smoke like that," says Eduardo. "My glasses immediately turned black from the ash." As the fire spread across the hall, Eduardo banged on the bedroom door and tried to turn the handle. But Cody didn't respond, and Eduardo made his way back downstairs. At the same time, Marcos saw Yim and Suzanne pulling an aluminum ladder out of the garage. "Cody was standing at the window, screaming for help," says Marcos. "I knew I had to do something." He grabbed the ladder, positioned it near the window, and climbed towards the boy. When Marcos reached the window, he pushed the screen into the room and persuaded Cody out. "It's OK," Marcos told him. "I've got you." Holding Cody with one arm, Marcos moved down the ladder. Halfway down, he handed the boy to a neighbor. The day after the fire, Alex visited Marcos. "Thank you for saving my son," Alex said. "You are his hero forever." Question: When the Ugartes got to the fire scene, _ . Options: A: the Mas were all out to safety B: father Alex Ma was saving his son C: Cody was trapped on the second floor D: Cody was sleeping in bed
