I'm taking a test and have to guess the right answer to the question after the article. Article: Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily. Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind. Since 1960 a new kind of tool has appeared. This is the silicon chip . It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it? Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now? Question: The stone chip is thought to be the most important tool because it _ . Options: A: was very important to the development of mankind B: led to the invention of machines in the early time C: developed cooking abilities of mankind D: was one of the first tools of mankind

I'm taking a test and have to guess the right answer to the question after the article. Article: "Confidence" is probably one of the most noticeable traits in the Americans. They show confidence in the way they talk, the way they smile, the way they dress and the way they walk. Living and competing with all these confident American students, I find it extremely important to be confident as an international student and instructor. As a student, being confident means you should never hesitate to raise your hand whenever a question or a point comes to your mind. Don't mind if it sounds simple or silly. Otherwise you will never get a chance to speak in class at all. What's worse, the professors may think you are not prepared for the discussion or you do not have your own opinion on the issue--this is the last comment any graduate would like to receive. Being confident for me as a foreign instructor means calmly asking the student to repeat what he or she has said if I did not get it. Pretending to understand what you actually did not may just bring yourself embarrassment or even disgrace. But the time I most need to be confident is when my students come to my office and bargain about the grades I have given for their speeches. (The course I'm teaching here is Public speaking). Modesty is a trait highly valued in China, but it won't be of much help here if you want to survive and succeed in a good American graduate program. Question: A professor will have the worst opinion of a student who _ . Options: A: gives a silly or simple answer B: tries to seize any chance to speak in class C: shows no interest in the course D: is considered to have no opinion of his own
(Answer)
D
