I'm taking a test and have to guess the right answer to the question after the article. Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make. Question: Leave a pail with warm water and another pail with cold water in the same low temperature, you'll find that _ . Options: A: cold water freezes first B: warm water turns into ice before cold water C: warm water and cold water freeze at the same time D: much of cold water is changed into air.

I'm taking a test and have to guess the right answer to the question after the article. Article: In many businesses, computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is "untouched by human hands" and therefore safe. But they have no thought that the growing number of computer crimes show they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last. Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records. Most computer criminals have been common workers. Now police wonder if this is "the tip of iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know a computer works." Question: This passage is mainly about _ . Options: A: computer crimes B: stealing through computers C: computer mistakes D: punishment through computers

I'm taking a test and have to guess the right answer to the question after the article. Article: It's difficult not to become involved in gossip at work. After all, people like gossip and interesting bits of information: you only have to look at the number of celebrity-focused publications to realize that we have a huge appetite for discussing other people's lives. At work, however, this type of interaction is harmful and costly. It wastes time, damages reputations, promotes divisiveness , creates anxiety. Rumors often grow because people like to be "in the know." Knowledge is power, and that's why the people with the least amount of power in an organization can often be the ones to start and spread rumors. It can make them feel important if they're seen to know things that others don't. This knowledge is at the center of why and how rumors start and spread. Insufficient knowledge or incomplete information are often to blame. Consider these examples: *People don't know why a colleague was fired, so they make up a reason based on some limited knowledge or insignificant fact. "I saw John override the cash register the other day without a supervisor present. Maybe he stole some money and that's why he went." *People see a pattern of behavior between two individuals and they add their own explanation. "Joseph and Samantha spend a lot of time together after hours 'catching up on paperwork.' And just yesterday, they were sitting awfully close to each other in the meeting. I bet paperwork isn't all that's getting done after work!" These rumors are typical of the things you'll face at work, and they spread because of a lack of accurate information. So, the best way to fight rumors is with good communication. When you communicate well, your team knows what's happening, and they trust that you'll keep them informed. Good communication within your team also means that you will become aware of any rumors that are starting, and you'll be able to address them quickly and effectively. Question: What is the relationship between Joseph and Samantha in the eyes of the people spreading rumors? Options: A: They are lovers. B: They are work partners. C: They are rivals. D: They are old friends.
