*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: It is pretty much a one-way street.While it may"be common for university researchers to try their luck in the commercial world,there is very little traffic in the opposite direction.Pay has always been the biggest _ ,as people with families often feel they cannot afford the drop in salary when moving to a university job.For some industrial scientists,however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70%cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge.Her main reason for returning to academia halfway was to take advantage of the greater freedom to choose research questions.Some areas of research have few chances of a commercial return,and Lee's is one of them. The powerful effect of a salary cut is probably less severe for a scientist in the early stages of an occupation.Guy Grant,now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge,spent two years working for a medicine company before returning to university as a post-doctoral researcher.He took a 30%salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder,where a pay cut is usually more significant,the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive,according to Lee.Industrial scientists tend to receive training that academics do not,such as how to build a multidisciplinary team,manage budgets and negotiate contracts .They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate,says Lee,perhaps experience in manufacturing practice or product development."Only a small number of undergraduates will continue in an academic occupation.So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who... Question: What contribution can industrial scientists make when they come to teach in a university? Options: A: Suit its research to practical applications. B: Develop its students'potential in research. C: Help it obtain financial support from industry. D: Increase its graduates'competitiveness in the j ob market.

I'm taking a test and have to guess the right answer to the question after the article. Article: Advertisement is the difficult business of bringing information to great numbers of people.The purpose of an advertisement is to make people respond to make them react to an idea,such as helping prevent forest fires,or to make them want to buy a certain product or service.At the beginning of the 20th century,advertisement was described as"salesmanship in print".If this definition were expanded to include radio and television,it would still stand today.The most effective way to sell something is through person-to-person contact.But the cost of person-to-person selling is high because it takes a great deal of time,and it increases the cost of the product or service.Advertising distributes the selling message to many people at one time.The first printed advertisement in the English language appeared in 1278,more than a century before Shakespeare's first play was produced.This early advertisement was the work of William Caxton,England's first printer,who used it to advertise religious books from his own workshop Caxton posted small printed notices along London's main streets.Besides advertising his product,he identified his shop with a red-striped shield so that customers could find it easily. This same sort of simple informational advertising is still used.Examples are the roadside signs that tell travelers that they can buy fresh corn just down the road or that there is a restaurant in the next town. The Industrial Revolution,in the 18th and 19th centuries,brought a new kind of advertising.Large factories took the place of small workshops and goods were produced in large quantities. Manufacturers used the newly built railroads to distribute their products over wide areas.They had to find many thousands of customers in order to stay in business.They couldn't simply tell people where shoes or cloth or tea could be bought---they had to learn how to make people want to buy a specific product. Thus modern advertising was born. Advertising created new markets and helped to raise standards of living as people came to... Question: Modern advertisement was born as a result of_. Options: A: the Industrial Revolution B: the newly built railroads C: the appearance of the first printer advertisement D: people's need

I'm taking a test and have to guess the right answer to the question after the article. Article: When you choose a freezer, remember it's probably going to be with you for a long time. So it's important to know which freezer is right for your needs. First, decide if you want an upright or chest model. Uprights are more convenient. Their storage space is more accessible and they take up less floor area. However, chest models are more energy-efficient because less cold air escapes when they are open. If you are buying an upright, you'll have to choose between frostless or manual defrost . Chest freezers are always manual. Frostless freezers automatically defrost at present intervals and remove the water. Manual models must be defrosted by hand every few months or whenever frost pile up to about a quarter of an inch. To help your freezer reach a ripe old age, try to find a spot that's cool, dry, and away fromdrafts . Drafts and heat will raise the freezer's cabinet temperature, which makes it work harder to keep cool. That means wasted energy. That means wasted energy and a shortened life. Dry air is important because highhumidity can cause the freezer to rust outside and frost up inside. With proper care, a freezer can serve you for 15 years or more. Regular cleaning and simple maintenance will help it maintain a zero-degree temperature and keep it smelling fresh and looking almost new. Frostless models requires less care than manual defrost freezers. The inside of a frostless unit should be washed periodically with warm water and baking soda or a mild soap, rinse, and dried. Good habits go a long way toward a freezer that runs efficiently. To get the most from your freezer, check regularly to make sure it's providing a true zero-degree temperature. Keep the freezer at least three-quarters full. The emptier it get, the more energy is wasted. If more than three pounds of food per cubic foot of storage space is added every 24 hours, the resulting high or low temperature can damage the food. Question: In order to get the best results, you should _ . Options: A: use cool water to wash the inside of frostless models B: keep the freezer at least 75% full C: add three pounds of food every 24 hours D: put your freezer in a garage with a strong floor
