Q: I'm taking a test and have to guess the right answer to the question after the article. 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: It is _ for a criminal to deny his crime when finger-prints are used to identify him. Options: A: worth trying B: successful C: useful D: useless
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: It is difficult to imagine what life will be like without memory. The meanings of thousands of everyday perceptions(, ), the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory. Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat. Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices from storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"--ready for instant use. An average prefix = st1 /U. S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction(, ) of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight. The use of words is the advanced problem-solving intelligence of human beings. A large part of a person's memory is in terms of words and combinations of words. Question: The topic of the passage is _ . Options: A: What would life be like without memory? B: Memory is of vital importance to life. C: How is a person's memory different from an animal's or a computer's? D: What is contained in memory?
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device developed by doctors in Israel. The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine. With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs. Ten healthy people easily mastered sniff--driving a wheelchair through a maze , and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair. At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study. Question: What's the purpose of the passage? Options: A: To introduce a new invention. B: To equip the disabled with life skills. C: To show the nose's special functions. D: To instruct doctors to apply for a patent.
A: A
