Question: Article: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction.

Options: (A) It can be washed in a washing machine. (B) It is much heavier than a leather purse. (C) It can download songs from the Internet. (D) It is made of clothes conducting electricity.

Answer: A

Question: Article: Let's pretend we're sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It's interesting to watch the many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world. Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei. Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren who has lured many sailors to their deaths. The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her forget to steer , and the current of river hurls their boats on the rocks and dashes them to pieces. Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.

Question: Article: "The first and best of victories is for a man to conquer himself; to be conquered by himself is, of all things, the most shameful," says Plato. Selfcontrol is at the root of all the advantages. Let a man give in to his impulses and feelings, and from that moment he gives up his moral freedom. A single angry word has lost many a friend. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. _ "Keep cool", says George Herbert, "for fierceness makes error a fault." To be angry with a weak man is to prove that you are not strong yourself. "Anger," says Pythagoras, "brings with folly and ends with regret." You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him. Selfcontrol is man's last greatest victory. If a man lacks selfcontrol he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no selfconfidence, for he will always be controlled by his strongest feeling. If he lacks selfcontrol, the very backbone and nerve of character are lacking also.
