Question: Read the following article and select the best answer. Article: To be successful in any aspect of life, you need to know when to use the carrot or the stick. Here are a few tips to help you decide whether it's better to use the carrot or the stick. With the kids The carrot When it comes to raising a kid, the carrot or the stick dilemma is quicklydisappearing as too many parents take the carrot approach to the extreme. In child raising, the carrot should never be materialistic things. If you want to ask for good behavior with a reward, it should be with something that can't be bought, say, trust. The stick Nowadays, no one likes to use the stick any more, or in my father's case, the belt. I'm not overlooking child abuse, if you ever want to call it that, but I am encouraging parents to toughen up a bit. You don't want your kid to test your limits only to find out he can get away with it. If you want to raise a kid, raise the hand and let him know it comes down on the second offense. At the office The carrot People need encouragement and motivation to perform well. However, the carrot only really works well with employees who have already proved themselves. Ifyou've got someone who can't show up at the office before noon, the promise of a raise isn't going to do much. On the contrary, if there's a guy with a good work moral, he'll thrive (grow stronger) when you add a promotion to the picture. The stick When considering the carrot or the stick in the office, remember that, overall, the stick is the more practical method in the office. A wise man, who just happened to be an Italian, once said "It's best to be both loved and feared." It's nice to have everyone love you, but running a business isn't like running a family. You need to have the stick constantly raised. With the wife The carrot When it comes to marriage, always use the carrot. I've had a lovely marriage for many years, and I've always stuck to the carrot approach. Sometimes you catch more flies with honey, and sometimes it's the crack of a whip that gets the horse moving. Try not to use too many sticks at home;... Question: In kids raising, the author prefers _ . - the carrot approach - the stick approach - both the carrot approach and the stick approach - neither the carrot approach nor the stick approach

Question: Read the following article and select the best answer. Article: Before we send humans into deep space, we'll have to find out just how long the human body can survive in a weightless environment. One problem is that in space there's no physical sensation to let you know when you're upside down and astronauts have to rely on possible clues from their surroundings. A few hours after reaching orbit , one in three of all astronauts will experience space sickness--a feeling rather like carsickness. There is also the problem of protection from the extreme hazards of space such as constant meteorite bombardment and radiation. It is going to take some clever technology to keep rockets and astronauts from these dangers. Even with a well-protected spaceship, space travel isn't going to be easy. No matter what you travel in, it is going to be a long flight in space! Science fiction writers often imagine using suspended animation , a kind of forced long-term sleep, as a way for astronauts to escape the boredom of long missions. An even stronger measure might be to freeze the astronauts. We already use cryogenic techniques to preserve dead bodies and store human embryos . Freezing living adults may not be so far away, but perhaps we don't have to do that. Perhaps we should use our existing technology and send frozen embryos to the far corners of universe. Hundreds of years from now, billions and billions of miles away, the embryos will be thawed and their hearts will start beating. These astronauts of the future will not grow inside a mother's body but will be produced in a machine. They will be brought up by robot. It may seem strange but one day it might just happen. Question: We can learn from the passage that _ . - scientists already use existing technology to store embryos for space flight - cryogenic techniques will practically be used for space flight in hundreds of years - it may be easier to freeze embryos than to freeze adults on the spaceship - most astronauts will suffer from space sickness
Answer: cryogenic techniques will practically be used for space flight in hundreds of years
