[EX Q]: 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

[EX Q]: Article: We like people who look like us, because they tend to have personalities similar to our own. And, a new study suggests, the longer we are with someone, the more similarities in appearance grow. Researchers set out to study why couples often tend to look like one another. They asked 11 male and 11 female participants to judge the age, attractiveness and personality of 160 real-life married couples. Photographs of husbands and wives were viewed separately, so the participants didn't know who was married to whom. The test participants rated men and women who were actual couples as looking alike and having similar personalities. Also, the longer the couples had been together, the greater the similarities. The researchers guess that the sharing of experiences might affect how couples look. The idea that there is a connection between appearance and personality might seem strange at first, but there could be biological reasons for a link, said study member Tony Little from the University of Liverpool in England. "The face displays our emotions and over time, emotional expressions may become written in the face," Little told Live Science. For example, someone who smiles a lot may develop lines and muscles that are suggestive of someone who is happy. Other studies have shown that partners who are genetically similar to each other tend to have happier marriages. The new study indicates that people have different features when using facial appearance to make decisions about someone's personality, and that the particular cues focused on change from face to face. Vital to the decision, however, are eyes and smiles. "Smiles are important social cues that may tell us whether or not someone is friendly, and eyes are also a traditional focus of attention," Little said. Overall face shape can be important too. For example, the combination of large chins and strong brow ridges can create an impression of disagreeableness and being unwilling to cooperate, Little said.
Question: Why do we like those who look like us?
Options: (A) Because they tend to like us. (B) Because opposites usually attract each other. (C) Because their personalities are similar to ours. (D) Because we often marry those who look like us.

[EX Q]: Article: Tips for Cycle Trips Cycling has many advantages as a form of travel, as it is the fastest way to travel by human Power, and slow enough to allow the type of local involvement that is impossible with powered travel.Cycle travel is a cheap form of transportation. Distance On level terrain ,without a headwind, a cyclist of average fitness on a touring bike can comfortably cover 60-120km a day.Distances of up to 250km a day are possible, but anything much beyond 120km will require considerable physical tension and not allow many stops to enjoy the places you visit.For many,80-100km a day will be the most suitable distance to aim for, as it will give a sense of achievement and also leave plenty of time for meals and activities. Geography The gradient of the trip will reduce your range.A basic rule is that for every 100 metres of altitude you climb, you should add an extra 15 minutes to your journey time.In hilly or mountainous areas, the easiest routes for cycling are downstream along major rivers, as overall they will be downhill.A long, roundabout route along a river will usually be easier than a short, direct route over a hill or mountain pass.However, it is worth bearing in mind that the most scenic routes often come from hilly terrain. Eat Food choice depends largely on where you are, so see the respective sections for more information about foods. As you will be working hard, it's important to get enough energy in your food.
