Question: Article: The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color.If they can sense color differences, then perhaps we, too, are affected by color without knowing it.Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics should never be packed in brown.These discoveries have grown into a whole subject of color psychology. Some of our preferences are clearly psychological.Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement.Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind.People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure.Red is exciting.Pure blue has exactly the opposite effect; it is a calming color.Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.

Options: (A) tried colors on blind people (B) found out that colors affect sales (C) developed a special subject of color psychology (D) discovered the relationship between color and psychology

Question: Article: 79 Mayfair Road Plumton, Kent October 10th Dear Rosemary, I was very glad to get your letter this morning. I really ought to have written to you---it was my turn, I know----but I have been terribly busy. The children seem to take up all my time. I am thinking of sending Ann to a nursery school. She'll be four next month. Baby has just started to walk and doesn't give me a moment's peace. But you know what it is like! How are all your children? I'm sure they love living in the country.

We are free that day and should love to come. We're longing to see your house. Let me know, then, if the Sunday after next suits you. May we come for lunch? We'd like to leave fairly early in the evening to avoid the heavy traffic on the roads. Love from us all, Edna

Question: Article: As the oldest university in the English-speaking world, Oxford is a unique and historic institution. There is no clear date of foundation, but teaching existed at Oxford in some form in 1096 and developed rapidly from 1167, when Henry II banned English students from attending the University of Paris. From 1878, academic halls were established for women and they were admitted to full membership of the University in 1920. Five all-male colleges first admitted women in 1974. St Hilda's College, which was originally for women only, was the last of Oxford's single sex colleges. It has admitted both men and women since 2008. By 1200, the town of Cambridge had at least one school of some distinction. Then, in 1209, some scholars settled there. By 1226 the scholars were numerous enough to have set up an organisation, and seem to have arranged regular courses of study, taught by their own members. From the start there was conflict between the town and the students. Students, usually aged about fourteen or fifteen, often caused disturbances; citizens of the town, on the other hand, were known to overcharge for rooms and food. King Henry III took the scholars under his protection as early as 1231 and arranged for them to be sheltered from exploitation by their landlords. The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts. Founded in 1861 in response to the increasing industrialization of the United States, MIT adopted a European university model and stressed laboratory instruction in applied science and engineering. The current 168-acre campus opened in 1916 and extends over 1 mile (1.6 km) along the northern bank of the Charles River basin. On April 29, 1911, Tsinghua Xuetang began its first term of study, and from that year on, the Tsinghua's anniversary has fallen on the last Sunday of April. Following the outbreak of the War of Resistance against Japan in 1937, Tsinghua University, Peking University and Nankai University combined to form the National Southwest Associated University in Kunming. After the war, Tsinghua University moved back to its original Beijing campus.
