Article: People have wondered for a long time how their personalities and behaviors are formed. It's not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive. Social scientists are, of course, extremely interested in these types of question. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from each other, and there is a great deal of debate between _ of each theory. The argument is often conveniently referred to as nature vs. nurture. Those who support the "nature" side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, characteristics and behavior is central to this theory. Taken to an extreme, this theory maintains that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts . Proponents of the "nurture" theory, or, as they are often called, behaviorists, claim that our environment is more important than our biologically based instincts in determining how we will act. Behaviorists see humans as beings whose behavior is almost completely shaped by their surroundings. Their view of the human being is quite mechanistic; they maintain that, like machines, humans respond to environmental stimuli (something that helps sb./ sth. to develop better and more quickly)as the basis of their behavior. The social and political connections of these two theories are significant. In the United States, for example, blacks often score below whites on standardized intelligent test. This leads some "nature" proponents to conclude that blacks are genetically worse than whites. Behaviorists, in contrast, say that the differences in scores are due to the fact that blacks are often... Question: The author is mainly concerned about solving the problem _ . Yes or no, is the answer "what makes different stages of intelligence"?
No

Article: Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic . To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we've had enough to eat; as a result, people often overeat . Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells. The body's metabolism becomes inactive, and then result is weight gain and obesity. The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common. To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize (...)the acid already accumulated in body. Eating the right types of raw and whole foods can help. it's also important to restore your enzyme balance. You need to identify and avoid the foods that... Question: . What can we learn from the text? Yes or no, is the answer "Eating the right types of raw and whole foods does good to our body"?

No

Ques: Article: Birds in cities are damaging their health by trying to sing above the noise of urban life. New research shows that male birds are trying to compete against traffic and city sounds.They are now singing louder and at higher frequencies,which could harm their vocal cords .Some birds are choosing to sing at night instead of during the day.This makes them more open to attack and also creates stress and exhaustion. "The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate.This could lead to inbreeding and a weak gene poo1."said Dr Sue Anne Zollinger of the.University of St Andrews. According to Zollingar,a bird group with a small gene pool might adapt less quickly to new diseases and could be wiped out. A study of the dawn chorus found that birds in Berlin sang up to 14 decibels louder than those in the forest.The birds sang loudest on weekday mornings. "By trying to sing over the sound of the city,birds ale rising vocal injury,"said Zollinger."All this puts the same strain on a bird's vocal cords as when a human need to shout to be heard--except that the birds are doing it all day,every day,"she said. "Singing under such pressure means birds have less control over the sound they produce.Their songs may lose quality and become more rough--sounding."said Zollinger.This could make them appear less attractive to female birds. Mark Constantine,author of The Sound Approach to Birding,said:"Birdsong is important for our quality of life and has been proved to reduce our blood pressure.When we live in the centre of large,urban areas,we get stressed and it's extremely good to have birdsong around us.The impact on humans of birdsong is massive.It harms us,as well as the birds,if their songs become louder and simpler. Question: It requires greatest efforts for birds in cities to sing on _ . Yes or no, is the answer "Friday mornings"?
Ans: No
