Read the following article and select the best answer. Article: 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... Question: With the discovery of gravitational waves, we'll _ . - create a new world - make full use of gravitational waves - view the universe in a new way - avoid being hit by black holes
view the universe in a new way

Article: Among a group of middle-aged men and women,who were discussing bringing about quality education ,was a young man dressed in a white shirt.Within minutes, he was called onto the dais .Twenty-two-year-old Babar Ali was surrounded by educators from across India.He was popularly known as the world's youngest head teacher.

"It all started as a game when I used to teach my sister, my first student, in my backyard.Later, some children from the village often came to my classes and that was how the school was born," he said. His biggest achievement is that six of his students have now started teaching in his school after their college hours. In another month, Babar's dream of a school building will soon come true.Many people, a large part of whom are from Karnataka,have helped him realize the dream.They have given his school a lot of money. Although he has received so much attention and recognition ,he is still not _ ."There are people in my village who do not go to schoo1.And there is a long way to go as so many children still need to receive an education,"he says. Question: The school Ananda Siksha Niketan was created by _ . - Babar Ali - six college students - a woman in Bhabta village - the West Bengal government

(Q).
Read the following article and select the best answer. Article: Riding was the favourite activity of Thomas Jefferson, who was the third President of the United States. He usually rode good horses. One day, he was riding outside Washington, when a jockey came near. He did not know the President, but his professional eye was attracted by Mr. Jefferson's horse. He stopped and said that he wanted to buy the horse, but Mr. Jefferson politely refused his offer. The jockey offered more money for the horse, because the closer he looked at the horse, the more he liked it. All of his offers were refused, which made him angry. He then became rude, but his rudeness left as little an impression as his money, for Jefferson had a very good temper. At last, he hit Mr. Jefferson's horse with his whip, getting it to run suddenly. This would have thrown a less skillful rider to the ground, but Jefferson stayed on his seat, and controlled his horse well. The jockey then gave up. He rode with Mr. Jefferson side by side and began to talk with him about politics. Jefferson joined in the conversation. When they got into the city and came close to the gate of the presidential mansion , Mr. Jefferson stopped, and politely invited the man to enter. The jockey was surprised and asked, "Why? Do you live here?" "Yes" was the simple reply. "Why, stranger, what's your name?" "My name is Thomas Jefferson." Embarrassed, the man quickly left, while the President looked at him with a smile and then rode through the gate.
