But the computer is placed in Sunnyside, about 80 kilometers away. What scientists input is sent by telephone lines to the computer, and after a time, copies of the designs are needed back in Felton as quickly as possible Lockheed people have tried several ways of sending the prints, but the most effective seems to be by pigeon. Are pigeons really used to carry messages in these days? They are, and they send the prints faster and cheaper than any other way. Human messengers are much more expensive and slower than the pigeons. The road to Felton goes through the mountains, and the driving is not easy. An electronic printout system could do the work in Felton, but at a cost of 10 dollars a print. Pigeons carry the designs for about 1 dollar each. Now Lockheed people have ten pigeon messengers. The pigeons do the work, and they have made Lockheed more famous. You can often read the news about pigeons in the newspapers around the world. Question: Something that's effective _ . - usually costs more - is something that works - is often unhappy - is often done by animals
is something that works

Read the following article and select the best answer. Article: The nation's largest group of pediatricians on Monday urged its members to "firmly oppose boxing for any child or adolescent." In a statement, the American Academy of Pediatrics (AAP) said thousands of boys and girls take part in the sport in North America, despite risks of serious brain and facial injuries. The group's position was approved by some experts. "There is very little one can do in order to increase the chance of having a healthy brain when you get old," said Dr. Hans Forstl, who has studied boxing injuries. " One of the best things you can do is avoid boxing." He said. According to the new statement, published in the journal Pediatrics, information from Canada shows a rise in boxing injuries over the past decade. Pat Russo, a retired police officer who runs a boxing gym in Brooklyn, New York, said injuries are rare in amateur boxing. After 26 years and training thousands of kids, he has seen just one split lip among his students. " If the gym is run properly, injuries are at an absolute minimum," Russo said. "Football is ten times more dangerous. While tennis or football might also help kids gain confidence, boxing holds a special attraction for children in poor neighborhoods, because it allows them to act tough while in trouble." Dr. Robert Cantu, a surgeon at Emerson Hospital in Concord, Massachusetts, said AAP's attitude makes sense for upper-class and middle-class kids. " Clearly boxing is safer today than it was 20 or 30 years ago, but it is still a very risky activity," he said. "For kids in poor areas, however, the situation is different," said Cantu. " The most dangerous thing for the majority of people in boxing is just where they live. They are far safer in the ring , even taking blows to the head, than they are out in the neighborhood." Question: What is Dr. Hans Forstl's attitude towards boxing for children? - Unconcerned - Supportive - Opposed - Neutral
Opposed

Article: Colleges taking another look at value of merit-based aid Good grades and high tests scores still matter--a lot--to many colleges as they award financial aid. But with low-income students projected to make up an ever-larger share of the college-bound population in coming years, some schools are re-examining whether that aid, typically known as "merit aid", is the most effective use of precious institutional dollars. George Washington University in Washington, D.C., for example, said last week that it would cut the value of its average merit scholarships by about one-third and reduce the number of recipients , pouring the savings, about $2.5 million, into need-based aid. Allegheny College in Meadville, Pa., made a similar decision three years ago. Now, Hamilton College in Clinton, N.Y., says it will phase out merit scholarships altogether. No current merit-aid recipients will lose their scholarships, but need-based aid alone will be awarded beginning with students entering in fall 2008. Not all colleges offer merit aid; generally, the more selective a school, the less likely it is to do so. Harvard and Princeton, for example, offer generous need-based packages, but many families who don't meet need eligibility have been willing to pay whatever they must for a big-name school. For small regional colleges that struggle just to fill seats, merit aid can be an important revenue-builder because many recipients still pay enough tuition dollars over and above the scholarship amount to keep the institution running. But for rankings-conscious schools in between, merit aid has served primarily as a tool to recruit top students and to improve their academic profits. "They're trying to buy students," says Skidmore College economist Sandy Baum. Studies show merit aid also tends to benefit disproportionately students who could afford to enroll without it. "As we look to the future, we see a more pressing need to invest in need-based aid," says Monica Inzer, dean of admission and financial aid at Hamilton, which has offered... Question: In recent years, merit-based aid has increased much faster than need-based aid due to _ . - more government funding to colleges - fierce competition among institutions - the increasing number of top students - schools' improved financial situations
fierce competition among institutions
