I'm taking a test and have to guess the right answer to the question after the article. Article: Whatever our differences as human beings are we all think we're more like the rest of the animal world than we realize. It is said that we share 40 per cent of our genetic structure with the simple worm. But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome . To help them do this, they turned to the worm. The nematode worm is one of the earliest creatures on planet earth. It is less than one millimeter long, completely transparent and spends its entire life digging holes through sand. But it still has lots to say about human life, and what can be done to make it better. What the worm told Sir John and his colleagues was that each of the cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded in our genetic make-up. Many of the diseases that humans suffer from happen when these instructions go wrong or are not obeyed. When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death. Question: What is the subject discussed in the text? Options: A: The theory of programmed cell deaths. B: A great scientist--Sir John Sulston. C: The programmed human life. D: Dangerous diseases.

I'm taking a test and have to guess the right answer to the question after the article. Article: Botany , the study of plants, occupies a particular position in the history of human knowledge.For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest ) of insights.It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient.This is logical.Plants are the basis of the food pyramid for all living things even for other plants.They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes.Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each.To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all. Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows.Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple.When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season--the first, great step in a new association of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture: cultivated crops.From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away. Question: We learn that the first great step toward the practice of agriculture is _ . Options: A: the changing diets of early humans B: the development of a system of names for plants C: the invention of agricultural implements and machinery D: the discovery of certain grasses that could be harvested and replanted

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: One of the most widely accepted, commonly repeated assumptions in our culture is that if you exercise, you will lose weight. I exercise all the time, but I still have gut fat that hangs over my belt when I sit. Why isn't all the exercise getting rid of it? It's a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study -- the Minnesota Heart Survey -- found, more of us at least say we exercise regularly. And yet obesity figures have risen sharply in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government's definition. Yes, it's entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don't. Could exercise actually be keeping me from losing weight? The popular belief that exercise is essential for weight control is actually fairly new. As recently as the 1960s, doctors routinely advised against too much exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases -- those of the heart in particular. They less often develop cancer and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly over-evaluated. "In general, for weight loss, exercise is pretty useless," says Eric Ravussin, exercise researcher at Louisiana State University. Many recent studies have found that exercise isn't as important in helping people lose weight as you hear so regularly in gym advertisements or on shows likeThe Biggest Loser -- or, for that matter, from...

Options: A: they have the habit of going to the gym regularly B: they eat the same food when they do not exercise C: they exercise less than required by doctors D: they eat more after they exercise
