Recently, however, P＆G broke with this long-standing tradition. Ariel, a P＆G laundry detergent, was born overseas, and is a familiar sight on store shelves in Europe and Latin America. Now bilingual packages of Ariel Ultra. a super-concentrated cleaner. are appearing on supermarket shelves in Los Angeles.
Ariel's appearance in the United States reflects demographic changes making Hispanics the nation's fastest-growing ethnic group. Ariel is a hit with this population. In fact, many Mexican immigrants living in Southern California have been "importing" Ariel from Tijuana, Mexico. "Hispanics knew this product and wanted it," says P＆G spokeswoman Marie Salvado. "We realized that we couldn't convince them to buy (our) other laundry detergents." P＆G hopes that non-Hispanic consumers will give Ariel a try too. Ariel's already strong presence in Europe may provide a springboard for the company to expand into other markets as well. Recently P＆G bought Rakona. Czechoslovakia's top detergent maker. Ariel, currently a top seller in Germany, is likely to be one of the first new brands to appear in Czech supermarkets. And Ariel is not the only foreign idea that the company hopes to transplant back to its home territory. Cinch, an all-purpose spray cleaner similar to popular European products, is currently being test-marketed in California and Arizona. Traditionally Americans have used separate cleaners for different types of surfaces, but market research shows that American preferences are becoming more like those in other countries.
Insiders note that this new reverse flow of innovation reflects more sweeping changes at Procter ＆ Gamble. The firm has hired many new Japanese, German. and Mexican managers who view P＆G's business not as a one-way flow of American ideas, but a two-way exchange with other markets. Says Bonita Austin of the investment firm Wertheim-Schroeder, "When you met with P＆G's top managers years ago, you wouldn't have seen a single foreign face." Today, "they could even be in the majority."
As Procter ＆ Gamble has found, the United States is no longer an isolated market. Americans are more open than ever before to buying foreign-made products and to selling U. S. -made products overseas.
According to the passage, which of the following is true？
A．The brands of Pampers, Crest, Ariel, and Cinch reflect the one-way flow tradition of Procter ＆ Gamble.
B．In spite of market changes, Procter ＆ Gamble still sticks to its long-standing tradition of one-way flow innovation.
C．Procter ＆ Gamble has to change its one-way flow tradition because of the increased number of its foreign managers.
D．Today one may meet more foreign faces in Procter ＆ Gamble than years ago.
Bone marrow or stem-cell transplants are usually a last resort, intended for those whose illnesses have not responded to traditional treatments such as chemotherapy or radiation. How do they work？ We all store a special type of cell in our bone marrow called stem cells. These primitive cells give rise to the three types of blood cells: red, white and platelets. Everyone's stem cells have certain genetic characteristics or markers that make them unique from others. Despite this uniqueness, there are some shared characteristics between people. This is important, because a patient's immune system will reject blood or organs received from someone else if they do not share sufficient similarities.
Family members, especially siblings, are always the first to be considered as donors, because there's a greater chance that the genetic markers on their cells will have enough in common to prevent rejection after transplantation. In many cases, however, a familial match can't be found and then the search begins for an unrelated donor. These donors typically come from a pool of people who have already signed up on a donor registry in the event that their cells match a needy recipient.
Once the lab has verified a match between donor and recipient, the next phase starts. The patient is given radiation or chemotherapy to kill the unhealthy cells. Healthy cells are harvested from the donor — either extracted from the pelvic bones or taken from the arm in a way that is similar to having blood drawn — and prepared in a laboratory. Once they're ready, they're given to the patient through a vein — the same way as one would receive a blood transfusion. Once these transplanted donor cells get settled within the patient's bone marrow, they make the healthy red blood cells, white blood cells and platelets necessary to support life.
One of the major problems currently faced by transplant centers is that while bonemarrow transplants can cure more than 70 different diseases, there aren't enough donors on the registry to treat the more than 3,000 patients awaiting transplants. The National Marrow Donor Program, the largest registry in the country, has approximately 4.8 million adult volunteer donors, but that isn't nearly enough for the thousands who need transplants.
Why isn't a pool of more than 4 million donors isn't enough to cover 3,000 needy patients？ Here's the reason: in the vast-majority of cases, finding a suitable match isn't easy. Because we are unique individuals with a variety of ancestral backgrounds and integration patterns, finding someone similar to us is a major task. In the end, it comes down to a numbers game — the more potential donors listed on the registry, the greater a chance of finding a match, especially for those with unusual genetic characteristics.
The shared genetic characteristic of stem cells is important in bone marrow transplant because ______.
A．the same primitive cells can produce the same type of blood cells
B．one's immune system will reject the blood or organ of different genetic markers
C．one's immune system will not reject the organ of the same type of blood cells
D．the uniqueness of genetic characteristics will destroy the patient's immune system
