[单项选择]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 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. "

[单项选择]{{B}}Passage Two{{/B}}
Antiseptics(杀菌剂) have saved countless lives, but they are most effective when the bacteria they are attacking are individual cells in suspension. Once bacteria have attached themselves to solid surfaces and formed films, they are far harder to eradicate with standard disinfectants. Bacterial pollution of medical devices is a particular problem, as those devices are then used on people whose immune systems may be in less than best condition. Surgical instruments may be treated with ultraviolet light, but that is not appropriate for everything. The result is that infections arising from bacteria attached to surfaces in clinics and hospitals are reckoned to cause up to 1.4m deaths per year.
In order to develop a better method of disinfection, a team led by David Whitten of the University of New Mexico and Kirk Schanze of th
