Hundreds of people lined up at Grand Central Terminal yesterday, but they weren't there to catch a train. They came to New York City's famous railroad station to trade in old dollar bills for the new George Washington Presidential1 coin. The gold-colored coin is the first in a new series by the U.S. Mint that honors former U.S. Presidents. The Mint will issue four Presidential1 coins a year through 2016. Like the popular 50 State Quarters program, which issues coins in the order in which each state joined the Union, Presidential1 coins will come out in the order in which each President served. The George Washington coin is the first to be released. John Adams, Thomas Jefferson and James Madison coins will come out later this year. The Presidential 1 coins will be the same size and color as the Sacagawea Golden Dollar. However, there is an important difference. For the first time since the 1930s, there is an inscription on the edge of each coin. Each coin will show a different President on its face, or head side. It will also show the President's name, the order in which he served and his years in office. The other side of the coin will show the Statue of Liberty and the inscriptions "United States of America" and " 1". There will be one Presidential1 coin for each President, except Grover Cleveland. He will have two! Cleveland is the only U.S. President to have served two nonconsecutive terms. The last President scheduled to get a coin is Gerald Ford because a President must have been dead for two years before he can be on a coin. In which order will the Presidential1 coins come out? A) Each state joined the Union. B) Each President was born. C) Each President took office. D) Each President died.

The First Hello The man from the telephone department got off the bus, and made his way to the tea stall, wiping the sweat off his head, face, then slipping his handkerchief under his shirt to wipe his neck and back. It was a year ago that the phone line had been installed, six months later men from the public works department had come to put up the phone booth -- a neat box-like structure, with a glass window, and wooden ledges, yellow in colour. And days after that, a painter had taken an entire day to colour in broad, black brushstrokes, the words: STD Booth, local and STD allowded. No one could tell that the last word had been misspelled. Besides, he had taken the entire day. After he had a cup of tea, he had left, waving cheerfully. And now months later, someone else was here again. Everyone watched the man as he sat on the bench. No one said a word, and soon the sound of him slurping his tea filled the hot afternoon. A few leaves fell, heavy in the heat, and sometimes a car passed, on its way to the main city farther away. When the man had finished, he made to pay but the tea shop owner who sat behind his steaming kettle and the washed upturned cups, waved him away. "You are our guest here." So the man took his handkerchief out again and wiped his face. They crowded around him as he shut himself up in the phone booth. When the children pressed their nose against the glass, he shooed them away, as he took out a shiny black instrument and placed it on the narrow shelf. A sigh of satisfaction passed through everyone that soon changed to an excited yell as they saw him dial a number, pressing a finger into the ringed dialer of the phone and letting it go all the way in a half-circle. A while later, they hear him say into the mouthpiece, "Hello." "Hello, " the children around the booth took up the cry, the teashop owner broke into a smile and the men waiting for a bus smiled and said hello to each other. The sadhu who sat under the banyan tree nodded wisely. As the sound carried, more hellos were heard.... What can be inferred from the story? A) The man from the telephone department had a mentally demanding job. B) Only the minister had the authority to make the first call. C) It was a distant village free from modern technology. D) Few of the local children went to school for education.

It took 100 years, but finally, scientists proved Albert Einstein's theory that gravitational waves exist. The waves were predicted as part of Einstein's general theory of relativity nearly 100 years ago. It was the theory of the physics behind the workings of our world and the universe. The idea was that the waves are like ripples in space, caused by some of the violent and energetic processes in the universe. For example, two black holes crashing into each other. Now a group of scientists, including ones from Caltech, MIT and the LIGO Scientific, Collaboration finally found the gravitational waves. David Reitze is the executive director of the LIGO observatory at Caltech. "We have detected gravitational waves. We did it!" What are these gravitational waves? Well, imagine throwing a rock into a pond. When the rock hits the flat surface of the water, it creates ripples or waves. Space-time is like the surface of the water. So that means gravitational waves are like the ripples moving out from where the rock hits the water. It might be hard to understand, but those gravitational waves expand and contract space and time as they move through space. And when they get to the Earth, the waves pass through, and they contract and expand the planet as the waves go by. It was Einstein who said these gravitational waves should be observable. But these are not huge waves. They are very, very small, which is why it took so long to find them. You cannot see them with your eyes. They are smaller than the size of an atom. How did the scientists find them? They used a giant scientific tool called LIGO, which stands for the Laser Interferometer Gravitational-Wave Observatory. The billion-dollar LIGO project is two L-shaped observatories. One is in Louisiana and the other in Washington state. For years, scientists have been watching two black holes in another faraway galaxy. The two were spinning around each other, moving closer and closer together. When they finally crashed into each other, it was with such power and force... With the discovery of gravitational waves, we'll _ . A) create a new world B) make full use of gravitational waves C) view the universe in a new way D) avoid being hit by black holes
