PROBLEM: Article: If you don't prepare yourself now, retirement may be some of the most boring and dull years of your life. To have a happy, fulfilling retirement, you need to start preparing right away. The most obvious thing for people to do when they retire is to take up a hobby. The most important step to take before retiring, though, is to make sure that you actually have started some hobbies. Once you're retired, unless you 've already started a hobby, you'll find it very hard to get into something new. Some hobbies aren't for everyone. Think about what you enjoy doing and start participating on a casual basis now. Another thing many people participate in is volunteering. Not only does volunteering give you something to do, it also gives you a sense of accomplishment and can add meaning to your life .Volunteering is also rewarding in other ways, too. There are hundreds of different types of volunteer services and you'll always be able to meet new and interesting people. Also, don't think that volunteering is always only about helping someone for free. Many companies pay their volunteers after they've had enough experience and prove themselves to be valuable workers. There are plenty of other potions, as well. Going back to school is a great way to keep yourself feeling young. Taking a vacation around the world with your loved ones is another great way to spend your retirement. Ultimately, though, the key to a happy retirement is simply keeping yourself busy and doing whatever you love. If there's nothing you love doing now, then you'll find that once you have a vast amount of free time, your life will be pretty empty. Now is the time to find out what you want to do when you retire.
Answer: Because we are likely to have difficulty starting a hobby after retirement.

SOLUTION: Why does the author suggest starting a hobby before retirement?

PROBLEM: Article: Recently Chinese society has seen a flowering of a new vocabulary. Perhaps the most interesting has been the division of people into tribes (zu in Chinese). The pains of the yi zu, or the ant tribe, have been well-known --- recent graduates from outside the main cities who move to urban areas, live cheaply and work hard, often in low-paid jobs. Perhaps less well-known are the ken lao zu, the bite-the-old tribe, those between 25 and 35 who are out of work, still at home and depending completely on Mum and Dad. Many of the tribes, inevitably , are made up of people looking for love. There is the jia wan zu, the marry-the-bowl tribe. These are young women searching for the most stable husbands, the ones who hold government jobs. The shan hun zu, or lightening-marriage tribe, marry fast and sometimes separate faster. They should not be confused with the yin hun zu, the hidden-marriage tribe. These are women in their 20s who hide the fact that they are married. And if you can only afford a postage stamp of an apartment, you're probably a member of the wo ju zu, the snail-house tribe. You can belong to more than one tribe. Most members of the ant tribe also belong to the ben ben zu, the rush-rush tribe, to which, in fact, most urban Chinese belong. All that rushing around can create a lot of anger, leading to the nie nie zu, the crush-crush tribe, so named because they go into supermarkets and take out their anger by standing in the passages crushing packets of instant noodles. Another famous one is the yue guang zu, or moonlight tribe, so named because the Chinese characters for "moonlight" sound the same as the phrase "spend all your monthly salary". Their parents save every coin, but life for these young people is just to spend, spend and spend.
Answer: Graduates from the countryside .

SOLUTION: Who probably belong to the ant tribe?

PROBLEM: Article: While car sharing is a concept that's catching on, old-fashioned carpooling where a group of people take turns driving each other to work has always faced a resistance . In a study on traffic problems by ABC News, 84% of those who drive to work say that they still do it alone. More than half those lone riders insist that carpooling is just too inconvenient, and 18% say they simple don't know anyone to share a ride with. Now technology makes carpooling easier and more fun. NuRide, a company provided an online carpooling service last year, offers daily travelers in the Washington area not just a web-based list of would-be carpoolers but also a way to arrange a trip online. Here's how it works: rider seekers enter the positions where their trip will begin and end, the time they want to leave and if they're willing to drive or just ride in someone else's car. The website's search engine then looks for matches and makes lists of the names of traveling companions, along with the car model and the exact time and place to meet for each trip. People who want to share the ride can show their interest in joining in online and then meet their car mates when it's time to go. NuRide users aren't riding with total strangers. They are required to provide the name of their employer and a work e-mail address, both of which need to be checked before being listed on the website. To attract users, NuRide offers a frequent rider prize: anyone who shares a ride gets a $1 credit. So far, 2,300 people have signed up. NuRide CEO Rick Steele said that more than 50,000 rides have been arranged on the website, resulting in 1.4 million fewer miles driven and 650 fewer tons of automobile emissions .
Answer: Most people think it is inconvenient.
