Farm animals provide man with food and material for clothing, leather and other products. Some, such as horses and oxen, provide transportation and power to pull machinery. Livestock gaze on about 40 percent of the United States land area.Cattle provide meat, hides and dairy products. Beef and dairy cattle account for about a third of all farm income in the U.S. Farms in the Midwest and sprawling ranches in the West raise most of the country’s beef cattle. The main Dairy’ Belt in the U. S. extends through the Northern states from New England to Minnesota. Eastern dairy farmers in Minnesota, Wisconsin and Iowa sell most of their milk to companies that make butter, cheese and evaporated milk.Hogs grow rapidly and provide meat and materials used to make many products. Hogs thrive on corn, and farmers in the Corn Belt of the Midwest raise more than two-third of U. S. hogs.Sheep and goats supply man with meat, wool and skins for leather. They are hardy animals that live well on poor grazing land.Poultry includes chickens, ducks, geese, turkeys and other birds raised for meat or eggs. Many farmers keep small flocks of chickens to supply their families with eggs and meat. But some U. S. farmers specialize in raising large flocks of meat or egg-laying chickens. They use scientific breeding and feeding methods.Some specialized farms raise mink and other animals for their fur, rabbits for meat, or silkworms for silk.

Of course, public universities are much cheaper. At these schools, tuition is (49)______ higher for out-of-state students than it is for those whose (50)______ residence is within that state. Tuition at community colleges (51)______ about half the in-state cost of public, four-year colleges and universities. For those that cannot afford the cost of a college education, (52)______ aid is the answer. Students in the U.S.A. receive about $20 billion per year in financial aid. In recent years, nearly 75% of students in postsecondary programs have been receiving some form of financial aid.

The funds for all of this aid come from three main sources—the federal government, state government, and private (56)______.

As an executive at a firm that provides IT consulting services to companies around the globe, I often think about the challenges the next generation of IT workers will face. This field is hugely complex and getting more so by the year. And today’’s IT job market is global. Future workers will compete with skilled people on several continents, not just at home. Who could possibly overcome such obstacles Thoughts like these were running through my head as I was at home the other night. Then I happened to glance up at my 15-year-old daughter Brianna, who was working on the computer across the room. Brianna was preparing homework with Microsoft Word, reading and answering e-mail, using Instant Messenger to carry on separate discussions with several groups of friends, listening to her iPod, and surfing the Web for input on her homework. My head began to ache just thinking about the mental effort. But Brianna didn’’t seem to mind. She was working well with these communication channels and typing away to the beat of her iPod as if it were the most natural thing in the world. Then it hit me: This thoroughly normal teenager was multiplexing her activity — maintaining a precise balance and constantly evaluating her open tasks, she applied just the right amount of attention to each, slicing time like a hub and doing it all on a demand basis. This was particularly startling because, although I consider myself an "IT expert," I would have trouble keeping more than three e-mails open at one time, let alone balancing all the chores my daughter was involved in. But there was nothing magic in her performance. All over town there were thousands of other kids doing the same thing. They are a generation that grew up with planned sports, academics, religious instruction, and social activities. They did algebra in the backseat of SUVs as they were shuttled between appointments. They learned to use technological tools that were barely dreamed of 30 years ago. And somewhere along the way, they perfected the art of carrying on multiple activities at once. In a phrase, they are the multiplexed generation, or Generation MUX. They are also perfect candidates for the next generation of IT workers. In the information age, information flow is virtual and digitized. The members of Generation MUX have adapted to that digital flow. They multitask better than their predecessors did. And as our field grows more complex, the Generation MUXers are perfectly equipped to cope — managing IT systems, communicating with colleagues, and absorbing critical new information all at the same time. They’’ll sustain a pace that would drive older, serial-minded IT folk like me crazy. What makes the Generation MUX the perfect candidates for the future IT workers
A. They can get the support of their predecessors.
B. They are good at using the new technological tools.
C. They get used to the digital flow of information and are good at multitasking.
D. They make full use of telecommunication.
