Article: Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he _ removed one egg a day from a kind of bird Plover's nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five--never four, never six--caterpillars for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd and even numbers of food pieces. These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks. Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can "count" only when the objects are present and only when the numbers involved are small--no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals' achievements simply are not equal to evidence of counting. They only show the results of clever, careful training. Question: Where does this text probably come from?

Article: China is the biggest market in the world, and many countries such as Germany, the USA, the UK and Russia do a lot of business in China. Let's have a look at some important tips to help you be successful when dealing with these nationalities. First, you must be punctual with Germans. Even 5 minutes late makes a bad impression. Being punctual is also very important in the USA. In the UK, it's important to be punctual for business meetings, but nobody expects you to be on time for a social event. Half past seven really means a quarter to eight, or even eight o'clock! With Russians, you should always be on time, though it is not unusual for them to be one or even two hours late! It is best to dress formally and wear dark colours when you meet people from all the four countries. In Russia, designer clothes are very common. Don't be surprised if you go to an office in the UK on a Friday and find everyone wearing jeans. Many companies have "dress down Friday", when people wear casual clothes. In Germany, first names are only used by family members and close friends, so be prepared to use titles and last names. In the USA you will usually be invited to use first names almost immediately. The British are quite informal and using first names in business is more and more common, especially among younger people. In Russia, however, nobody uses first names, so use titles and last names. In conversation, the British and the Americans value humour, and both like to talk about sport. The weather is also a good topic of conversation with the British and the Americans, but avoid talking about politics. In Russia, say positive things about their country, but avoid making complaints. The Germans, however, prefer to get straight down to business! So, use these tips, and you will be on your way to a successful international business career! Question: Which color should you NOT wear when meeting a person from the USA? Yes or no, is the answer "White."?
No

Article: I am in my father's house in Connecticut, sitting at a crowded table with my brother, my two sisiters and all our partners, talking about a tree. "He doesn't want it cut down." My sister says when my father has gone to bed and none of us speaks of the tree in his presence. "He says he usef to climb it when he was a boy." When I was last here, a year and a half ago, for my father's 90th birthday, Hurricane Irene drove seawater into the roads. The large tree that hangs over the houses swayed alarmingly, but it stayed up. Last October, Hurricane Sandy acused a great deal of damage. Six months on, many of the surrounding houses are on sale, but the tree that hangs over the house still stands. "That tree," my brother says, "has survived the two worst storms of the last 100 years." Though my brother thinks highly of the amazing staying power of the tree, my sister says that the tree should never have been planted: it stops light from reaching the house. My other sister's partner says that all trees fall down eventually. There is plenty of evidence for what he says: throughout the neighborhood, the ramains of similarly sized trees lie on their sides, with their roots in the air. During this discussion, I offer to pay a quarter of whatever is required to remove the tree. "A guy I talked to," my brother says, "told me it could cost us$10,000." As night wears on, the discussion becomes increaslingly meaningless. There is no point in reaching any kind of agreement, since the decision is not for us to make. It's my father's tree, and he has refused to cut down the only thing in the neighborhood older than him. Question: According to the text, the tree _ Yes or no, is the answer "is more than 90 years old"?
Yes

Article: For years I fought with the bird's nest that sat on top of my head-my Medusa hair.No matter what I did and how hard I tried, in no way could I make my unruly hair to my satisfaction. Growing up in a Russian-Jewish home with parents who thought North American styling products were something illegal such as drugs, I was never allowed to put them in my hair. "Why buy hair gel? Your hair is so beautiful naturally." my mother would say.The teens at school did not agree.From boys' not wanting to kiss me when we played spin the bottle in Grade 7 to being called the mop, I suffered from my hair. When I got to university, I believed my hair was a wall that stood between me and everything---finding a part-time job, getting a boyfriend, etc. If only I could find a way to manage the curls and put it behind bars, I told myself, I would feel secure and sexy.I tried everything: rollers, hairspray, gels and, at one point, an iron.Then, in my second year, a miracle happened.I was asked to be a hair model for Japanese hair straightening, a process by which the molecules of my curls would be broken and reset in a bone-straight position.I was the perfect candidate, the hairdresser told me.Although they said how hair relaxing could damage the scalp , for the next five years I didn't find them to be true. All of the hairdresser's promises were fulfilled: With my hair straight and smooth, I was no longer the " mop". However, there was extreme damage done to my wallet. To keep up the straightening cost $ 700 every six months, and that was considered cheap. While some people thought I was crazy, I was willing to do anything to never again feel like that anxious, curly-headed girl in Grade 7.But when I moved out of my parents' house at age 26 and rented an apartment, the upkeep of my new image became too costly. I couldn't hide from my inner Medusa any longer.It was time to hug her and let her fly.Seeking a choice, I turned to the Internet, Google.After hours of searching, I hit upon a "curly haired" salon, a place designed for...
