Article: The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells. As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla , and unpleasant smells such as durians . The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water. Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change. Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results. One explanation is that women's sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.

Article: Counterfeit ( ) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money. The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The W.H.O. estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The W.H.O. says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit. Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms on their products as a security device.

Article: The skin which covers the tips of the fingers and thumbs is crossed by numerous ridges arranged in different patterns. These patterns are permanent from birth and remain exactly the same throughout a person's life, even when the skin becomes wrinkled and cracked as a result of old age. Such patterns are never passed on from parents to children, and no one in the world has the same patterns as anyone else. Even identical twins have different sets of fingerprints. As a result, fingerprints offer a most useful and _ way of identifying people. Any ridged part of the hand and the foot may be used as a means of identification, but finger impressions are usually preferred since they can be taken easily and quickly. Fingerprints are classified in the ways: by general shapes and contours , by the finger positions of the pattern-types, and by size (often measured by counting the ridges in the loops). Every set of fingerprints has different "ridge characteristics" (i. e. the print of each separate finger is different from that of all the other fingers), which belong to one of four basic groups: arches, loops, whorls and composites. All fingerprints can then be divided into 1, 024 groups. By using details in the patterns above, these 1, 024 groups can be further divided into thousands of smaller groups, thus making it possible to find a particular set of fingerprints in a few minutes.
Question: According to this passage, the true statement about human fingerprints is that _ .
Options: (A) people's fingerprints sometimes can be passed on from parents to children (B) people's fingerprints are unique but identical twins may have the same fingerprints (C) using fingerprints is the only way to identify people (D) people's fingerprints will not change in all their lives
Asnwer: D
