Article: When I was a child, I was shocked at the idea that my sisters could be my best friends. Now, I wouldn't have it any other way. At the time, the idea of my two sisters being my closest friends seemed strange to me. We fought all the time over toys, food, attention, what to watch on television--you name it, and we quarreled about it at some point. How could my sisters be my best friends? They weren't the same age as I. We all had our own friends in school. My mother never let the three of us forget that sisters are lifelong friends. Her wish like most parents' was to give us something that she never had. Growing up as an only child, she longed for siblings. When she gave birth to three daughters, the fulfillment of her dream had only just begun. She had given each of us a gift and she wanted to make sure we did not take that gift for granted. She would frequently tell us how lucky we were. But there were other, more subtle ways that she encouraged us to grow closer. She never showed favoritism to one daughter over the other, as not to cause jealousy or bitterness between sisters. She constantly took us places together--skating, shopping and swimming, so that we developed common interests. And when we were teenagers, Mom always punished us equally, giving us yet another bonding experience. We didn't always get along beautifully and fought just like any other _ . But somewhere in between Mom's lectures, the family vacations and the shared memories, we realized that our mother was right. Today I share things with my sisters that I do with no one else. My sister Cindy and I ran the New York City Marathon together, side by side, even holding hands when we crossed the finish line. When my sister Karen got married, I was her maid of honor . Cindy and I traveled through Europe together and even shared an apartment for two years. The three of us trust each other with our greatest secrets.

Article: One night in February 1962, John H. Glenn. Jr., flew over Australia. The man in the Mercury capsule was alone, but friendly voices reached him by radio. On the dark land 100 miles below, he saw a sprinkling of light. They marked the city of Perth, where people had turned on their lights as a greeting to him. In Friendship7, Glenn radioed, " The lights show up very well. Thank for everybody for turning them on." His capsule raced on to the east. During his three orbits(......) of the earth, Glenn could always reach one of eighteen tracking stations. Some of them were on ship at sea. Others were in the United States. Many of the stations had been built with the help of other countries. These countries allowed Americans to bring in radio equipment and set it up. Without the help of such lands as Nigeria , Zanzibar(,), and Mexico, there would have been breaks in the worldwide radio network. John H. Glenn. Jr., was the first America to orbit the earth. For his flight, the tracking network covered 60,000 route miles. Five hundred men worked in the stations along the route. Since his flight, the network has grown. Today, it covers more than 100,000 route miles and has about one hundred stations. One-third of these stations are outside of the United States. Question: This passage is mainly about _ . Yes or no, is the answer "the first American to orbit the earth"?
(Answer)
Yes

Ques: Article: Many American schools have a student exchange program with foreign countries. Along with this program,there is usually another one called the"American Host Family"program.As its name suggests,the program gets American families involved in foreign students' lives in America and offers homes for them. Foreign students generally welcome such an opportunity to have a"family"here,but there are also those who prefer to stay"homeless". Many American families volunteer to host foreign students.However,if there is a shortage of host families,schools also get in touch with local people and introduced foreign students to them. The"American Host Family"program changes in lengths of time.It can go from a few days to a few years,depending on each individual school.After the first year is over,it is up to foreign students and their"families"to decide if they want to stay together as a"family".American families can host as many foreign students as they like.They can either have several students or just one at a time.Many families start with new students each year while still keeping in touch with the old ones.Schools usually leave it to foreign students and their host families to decide their activities after both sides meet. My school, however, holds activities every year. On major holidays like Easter, Thanksgiving and Christmas,foreign students are usually invited to their thomes for dinner.Even schools that do not have host family programs often arrange students to get together with American families on these special holiday occasions.

Article: Our lives and our songs Do you ever listen to the songs that your parents like? Chances are that you don't. You probably think the music that they like is old and dull and that the songs on your playlist are much cooler. But here is what scientists found recently : People's music tastes change as they age, according to a study published in the Journal of Personality and Social Psychology. So it is likely that your own musical preferences will follow a similar path to your parents', whether you like it or not. We used to think that culture and personality are the only factors that affect one's music choice. But researchers at the University of Cambridge, UK, gathered data from more than 250,000 people over the past 10 years. They noticed that as people age, their social circumstances change, and so does their music taste. There are three musical periods that people pass through as they mature -- "intense ", "contemporary" and " sophisticated ". The first period comes in the teenage years , during which people like intense music such as punk and rock because teenagers tend to be aggressive and want to establish their identities as independent individuals. But as people move into early adulthood, their lifestyle changes --they socialize more and want to build close relationships with others. As a result, they become more fond of contemporary music ,such as pop and R&B, which is usually uplifting and danceable and played at parties where people hang out together and chat. When middle age comes, things have settled down for most people. This period will be dominated by more "sophisticated" music, such as jazz and classical, as well as more catchy music like country, folk and blues. " For many , this life stage is frequently exhausted by work and family, and there is a requirement for relaxing , emotive music,"Jason Rentfrow, a research member , told The Telegraph. But you must be thinking : "Aren't there old people who are still into rock music ?" Of course there are.... Question: What is the main purpose of the article ? Yes or no, is the answer "To present a new study about how people's music tastes change."?
No
