C With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A&M University researcher has been undertaking for the past five years in a project called "Noah’s Ark". Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine and a pioneer in embryo(胚胎) transfer work and related procedures, says he salutes the Chinese effort and" I wish them all the best success possible. It’s a worthwhile project, certainly not an easy one, and it’s very much like what we’re attempting here at Texas A&M--to save animals from extinction. " Noah’s Ark is aimed at collecting eggs, embryos, semen(精子) and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Kraemer says there would be enough of the basic building blocks to reintroduce the species in the future. It is estimated that as many as 2,000 species of mammals, birds and reptiles will become extinct over the next 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. "The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy. It take s a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort , "adds Kraemer, who is one of the leaders of the Missyplicity Project at Texas A&M, the first ever attempt at cloning a dog. "They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly applaud their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed. "How long will the Chinese panda cloning project take according to the passage

A:1 Year. B:3 to 5 years. C:2 years. D:25 years.

Passage Five
On a clear night you can see many stars in the sky. These stars are millions of miles away. Are there living things on any of the stars People have always thought about this question. They could not find the answer before now. Today scientists know more about space than ever before. Some machines can help them look for the answer.
How will scientists do this People can’ t go to the stars. The stars are far away. A person would take hundreds of years to the next star in a spaceship. So scientists are sending out radio signals. These signals travel in space at the speed of light. At that speed, radio signals will take 25 years to reach the next star. The signals ask "Is there anyone out here". Living things in space must have machines to hear the signals. We will not get an answer to our signals for more than 50 years. However, scientists are already listening. Someone from space may be trying to send signals to us, too.
Scientists also have sent large telescopes into space. A telescope can make things look larger. The telescopes are going around the earth. They are looking for life on other worlds. In the next few years we may get an answer to the question, "Is there life in space.

Radio signals will take ( ) to reach the next star.

A:25 years B:50 years C:hundreds of years D:a few years
