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.

question:
Article: A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon the beautiful castle where the wise man lived. On entering the main room of the castle, the boy was quite surprised: tradesmen coming and going, people chatting in the corners, and a small orchestra playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn. The wise man listened carefully to the boy's explanation of why he had come, but told him that he didn't have time just then to explain the secret of happiness. He suggested that the boy look around the palace and return in two hours. "Meanwhile, I want to ask you to do something," said the wise man, handing the boy a teaspoon that held two drops of oil. "As you wander around, carry this spoon with you without allowing the oil to spill." The boy began to walk up and down stairs of the palace, keeping his eyes fixed on the spoon. After two hours, he returned to the wise man. "Well," asked the wise man, "Did you see the Persian tapestries in the hall? Did you see the garden that took the master gardener ten years to create?" The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil. "Then go back and observe the wonders of my world," said the wise man. The boy picked up the spoon and returned to his exploration of the palace. This time he observed all of the works of art on the ceilings and the walls. When he returned, he described in detail everything he had seen. "But where are the drops of oil?" asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone. "Well, there is only one piece of advice I can give you," said the wise man. "The secret of happiness is to see all the wonders of the world, and never to forget the drops of oil on the spoon."
Question: When the boy arrived at the castle, he _ .

question:
Article: When we donate blood, a small amount is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh + or Rh-. The ABO system was discovered by Karl Landsteiner in the early 1900s. He was awarded the Nobel Prize for his achievements. There are four basic types of blood in the ABO system: A, B, AB and O. Everybody is born with one of these four types of blood. We get blood type, just like hair color and height from parents. Because of the substances contained in each type, the four groups must be _ carefully, If two different blood types are mixed together, it may put a person into an extremely dangerous situation. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. In an emergency, type O blood can be given because it is most likely to be accepted by all blood types, so it is often called the universal donor. However, there is still a risk. For the opposite reason, AB is sometimes called the universal receiver. However, because there can be so many reactions in the blood bank of the hospital. There is a relationship between your blood type and your nationality. Among the Europeans, about 45 percent have type O while 42 percent have type A. The least common is type AB. Other races have different percentage. For example, some American Indian groups have nearly 100 percent type O out of 100 donors in the world.
Question: The writer suggests that the third most common blood type among the Europeans is _ .
Options: (A) B (B) A (C) AB (D) O
Asnwer: B
answer:
No
