Read the following article and select the best answer. Article: Here in the Northeast, winter means coats and sweaters. And that means plenty of pockets for our growing stock of digital things. Summer, in fact, is a pocket-free zone. No pockets in T-shirts. No pockets in gym shorts. Those few pockets that can be used quickly become full of things. Mobile phone, PDA, MP3 player or CD player, digital camera -- it's enough to make your pants torn as you walk down on the stairs or through the parking lot. Attempts have been made to help these things, but without success. One way is to put them to your belt. A mobile phone often goes this way and it's easy for you to make a phone, but it gathered to your belt, so it becomes a little unpleasant when you sit. Another way is to carry a bag to put all these things into it, but it troubles when you use them. Designers have been puzzling over this problem for a while and one company has come up with a possible solution. Called the Scott e-Vest, it is a lightweight vest with more than a dozen pockets. Wearers have a lot of room for mobile phones, PDAs, CD players and much more. Better yet, built-in wiring system called PAN, for "personal area network" allows wearers to use their things in addition to carrying them about. Connect the mobile phone to the PAN, for example, you can answer a phone call by putting in your earpiece and pressing a button through the vest's fabric . At the same time, the wiring system keeps the headphones for your CD player in place and ready for instant use. Besides these things, the vest has pockets for keys, a pen and even a "cup holder" pocket for drinks. At about $160, the Scott e-Vest is not cheap. Finally, our growing pile of things will get smaller and fewer as they merge. Until then, a vest-like coat that keeps our things a accessible might be the perfect carrying case. Question: The main purpose of this text is to _ . - describe the shortcomings of the present clothes - introduce a kind of new hi-tech clothes - show how important the PAN is - explain why people bring so many things with them
introduce a kind of new hi-tech clothes

Read the following article and select the best answer. Article: It was around 9 pm. Before heading to dinner in Jayanagar T Block, I was told by my wife that the rickshaw fare would be 40 rupees. Anyhow I had 150 rupees in my pocket. My wife said that if the drivers of rickshaws see out-of-town travelers, they'll scam them one way or another. At a crowded stop, a young girl extended her hand through the iron bars on the side of our rickshaw to ask for some money. After we refused, or rickshaw driver started his remarks on giving. "Giving is good. Every human should give. But we should know how to give." The rickshaw driver continued, "Most of these kids are trained by some guy who keeps all the money. It's run like a business. All of us should give, but this is just not the right place to give." He talked a bit more before we arrived. I asked about the fare. "39 rupees," he said. Now, most people who get cheated end up saying, "Well, you know, I don't mind paying extra if it is a good guy but I refuse to be cheated." I gave him 40 rupees, and he gave me a 1 rupee coin in return (Most folks would just round up). So I put the coin in my wallet, and took out a 100 rupee note. "Can you do me a favor?" "Of course, sir," he replied politely. "We were talking about art of giving. You seem to know how and where to give. Can you put the 100 rupees to good use somewhere?" "Give me your address and I'll make sure I get a receipt of where I gave," He replied without hesitation. I didn't understand him at first. Then I smiled and told him, "I trust you." So on the way back, instead of taking a bus to my place, I walked for the whole distance since I didn't have enough money. It was almost 1 a.m and I had to wake up at 6 a.m the next day. But I still walked.

(Answer)
To warn him no to be cheated.

Question: Read the following article and select the best answer. Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.
