Article: It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream. However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why _ who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.

Article: BEIJING, prefix = st1 /China(CNN) ---China's economic growth dropped to 9 percent for 2008, according to numbers released by the government Thursday --- in line with expectations, but still the slowest rate the nation has seen in seven years. Economists are concerned about what the slowdown means for investment in the future, whether new projects will be undertaken in manufacturing companies and in factories. If not, it will translate into more job losses and erase any optimism about a rebound in 2009. Since 2001, Chinahas been used to double-digit growth as consumers buy Chinese goods. However, the export sector was hit hard in late 2008, with December exports down 2.8 percent. Consumer spending has mostly held up in China, as people there do not carry as much debt as their American counterparts and can continue to spend. Consumer confidence, however, is a problem, said Dong Tao, Asia chief economist for Credit Suisse. Infrastructure is the only thing driving the Chinese economy, Dong said. Tens of thousands of Chinese factories have closed, millions of people are looking for jobs and an untold number of migrants who can't find work may be leaving cities for good because of the slowdown, which would have been unheard of six months ago. Fourth quarter numbers showed growth at 6.8 percent. Goldman Sachs predicted 6.5 percent, down from 9 percent in the third quarter. For all of 2008, Goldman Sachs had predicted 8.8 percent, down from 11.9 percent in 2007.

question:
Article: Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case. The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take. Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident. When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
Question: Scientists and experts have proved that the pattern of a human being's finger skin _
Options: (A) is similar to his mother's (B) is valuable to himself only (C) is like that of others with the same type of blood. (D) is different from that of all others
answer:
D
