Question: Article: My friend Fowkes, tells a story of a class he took in 1930s, when books were short and expensive. On the first day the professor marched up to the blackboard, looked through his notes, cleared his throat, and began. Fowkes was the only student in the course. Once Fowkes fell ill and missed a class. When he returned, to Fowkes' s astonishment, the professor began to deliver not the next lecture in the sequence but the one after. Had he lectured to an empty hall in the absence of his only student? It was perfectly possible. Today, professors continue to lecture and students to listen much as they did. It' s time for us to abandon the lecture system and turn to methods that really work. Attending lectures is passive learning ,at least for inexperienced listeners. Active learning, in which students write essays or perform experiments and then have their work evaluated by an instructor, is far more beneficial for those who have not yet fully learned how to learn. Most students learn best by engaging in debate. They need small discussion classes that demand a joint effort of teacher and students rather than classes in which one person, however learned, expresses his or her own ideas. The lecture system harms professors as well. It reduces feedback to a minimum, so that the lecturer can neither judge how well students understand the material nor benefit from their questions or comments. Questions that require the speaker to clarify unclear points and comments that challenge inadequately constructed arguments are indispensable to scholarship. Without them, the liveliest mind becomes dull. If lectures make so little sense, why have they been allowed to continue? The truth is that lectures are easier on everyone than debates. Lectures give some students an opportunity to sit back and let the professor run the show. In a classroom where everyone contributes, students are less able to hide and professors have less room to show off how smart they are. Worse still, the lectures too frequently come at the wrong end of the students' educational careers -- during the first two years, when they most need close, even individual, instruction. If lecture classes were restricted to junior and senior undergraduates and to graduate students, who are more academically independent and more capable of working on their own, they would be far less destructive of students' interests and enthusiasms. After all ,students must learn to listen before they can listen to learn.
Answer: It is far from beneficial for those academically inexperienced students.

Answer: What can we learn about the current lecture system?

Question: Article: People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals each day. Low-calorie Diets Do Not Work The reason people cannot lose weight by starving themselves is that their metabolism will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight. Low-fat Diets Do Not Work Many people in today's society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle. Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.
Answer: They eat the wrong foods at the wrong time.

Answer: What is the main reason why people are overweight according to the author?

Question: Article: An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow perched on their window. The father asked his son, "What is this?" The son replied, "It is a crow." After a few minutes, the father asked his son the 2 time, "What is this?" The son said, "Father, I have just now told you 'It's a crow'." After a little while, the old father again asked his son the 3 time, "What is this?" At this time some expression of was felt in the son's tone when he said to his father. "It's a crow, a crow, a crow." A little after, the father again asked his son the 4 time, "What is this?" This time the son shouted at his father, "Why do you keep asking me the same question again and again, although I have told you so many times 'IT IS A CROW'. Are you not able to understand this?" A little later the father went to his room and came back with an old tattered diary, which he had maintained since his son was born. On opening a page, he asked his son to read that page. When the son read it, the following words were written in the diary: "Today my little son aged three was sitting with me on the sofa, when a crow was sitting on the window. My son asked me 23 times what it was, and I replied to him all 23 times that it was a crow. I hugged him lovingly each time he asked me the same question again and again for 23 times. I did not at all feel irritated, I rather felt affection for my innocent child."
Answer: Because his son used to love playing this game with him.

Answer:
Why did the old father keep asking his son the same question?
