I'm taking a test and have to guess the right answer to the question after the article. Article: For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright "tail" of burning gas. The comet Tempel 1 has an orbit far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface. The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet. "Right now we have lost one spacecraft," said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion. The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash. The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the _ of a comet.[:..] The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet. Question: The author's main purpose in writing the passage is to _ . Options: A: inform people the discovery of a new comet B: show the power of America in space. C: introduce the knowledge of comets D: introduce an experiment

I'm taking a test and have to guess the right answer to the question after the article. Article: Sometimes people call each other "freaked-cat", but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its bloodstream.Although the cat doesn't realize this, its body is getting ready for action.If the danger continues, the animal will do one of two things.It will defend itself, or it will run away as fast as it can. Something like this also happens to people.When we are excited, angry, scared, or aroused by other emotions (feelings), our bodies go through many physical changes.Our hearts beat faster, and our muscles get tense.All of these changes make us more alert and ready to react.We, too.get ready to defend ourselves or run. Human beings, however, have a problem that animals never face.If we give way to our feelings and let them take over, we can get into trouble.Have you ever said something in anger --or hit somebody--and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn't always clever to express your feelings freely. Does this mean that it's smarter always to hide our feelings? No! If you keep feelings of anger, sadness, and bitterness hidden away or bottled up inside, your body stays tense.Physical illness can develop.It can actually be bad for your health.(It isn't good to keep pleasant feelings inside either; all feelings need to be expressed.) Feelings that you keep all bottled up inside don't just go away.It's as if you bought some bananas and stuck them in a cupboard.You might not be able to see them.but before long you' d smell them.And if you opened the cupboard, chances are that you'd see little fruit flies flying all over them.They'd be rotten. You can try to treat emotions as if they were bananas in the cupboard.You can hide them and you can pretend they don't exist, but they'll still be around.And at last you'll have to deal with them.just like those bananas. Question: According to the passage, we may conclude that we human beings _ . Options: A: have fewer problems than animals B: have the same problems as animals C: have more problems than animals D: have cleverer problems than animals

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: The Marches were a happy family. Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Amy, and Marmee, as the March girls called their mother. The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always. The happy days passed and darkness came when a telegram arrived for Mrs. March. "Your husband is very ill," it said, "come at once." The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together. Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety. Amy was asked to go and stay in Europe with a relative of the Marches. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall. Beth had known for some time that she couldn't live much longer to be with the family and in the spring time she died. News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys. And so the little women had grown up and lived happily with their children,... Question: It can be inferred from the passage that the March family had _ . Options: A: both happiness and sadness B: wealthy neighbors C: more girls than boys D: a lot of rich relatives
