Article: How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. You might see stars where before you only saw dark space. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescope you can see more and more objects in the sky. And you can see those objects in more and more detail. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're invisible. They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. Imagine if the Earth were crushed until it was the size of a tiny marble . That's how tightly this dead star, a black hole, is packed. What pulls the star in towards its center with such power? It's the same force that pulls you down when you jump - the force called gravity. A black hole is so tightly packed that its gravity sucks in everything - even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness. So the next time you stare up at the night sky, remember: there's more in the sky... Question: Why can't you see light when you look at a black hole? Yes or no, is the answer "Because the gravity of a black hole is so strong that it sucks the light inward."?
Yes

Ques: Article: "It hurts me more than you," and "This is for your own good." These are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy to us. They thought that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation. Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we've made a terrible mistake. One such teacher is Sharon Klompus who says of her students - "so passive" - and wonders what happened. Nothing was demanded of them, she believes. "Television," says Klompus, "contributes to children's passivity. We're not training kids to work any more. We're talking about a generation of kids who've never been hurt or hungry. They have learned somebody will always do it for them. Instead of saying 'go look it up', you tell them the answer. It takes greater energy to say no to a kid." Yes, it does. It takes energy and it takes work. It's time for parents to end their vacation and come back to work. It's time to take the car away, to turn the TV off, to tell them it hurts you more than them but it's for their own good. It's time to start telling them "no" again. Question: Why are children becoming more inactive in study? Yes or no, is the answer "Because they spend too much time watching TV."?
Ans: Yes

Ques:Article: On a sunny day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea. Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control. Tim knew it would soon be swallowed by the waves. "Everything went quiet in my head," Tim recalls . "I was trying to figure out how to swim to the boys in a straight line." Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!" Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him. "Let's aim for the pier ," Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. "Can you guys swim?" he cried. "A little bit," the boys said. Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swam toward land as water washed over the boys' faces. "Are we almost there?" they asked again and again. "Yes," Tim told them each time. After 30minutes, they reached the pier. Question: Why did the two boys go to the sea? Yes or no, is the answer "To get back their football."?

Ans:
No
