Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Exercise seems to be good for the human brain,with many recent studies suggesting that regular exercise improves memory and thinking skills.But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect -- that is,if we think we will be "smarter" after exercise,do our brains respond accordingly?The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives. While many studies suggest that exercise may have cognitive benefits,recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect.So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana Champaign decided to focus on expectations,on what people anticipate that exercise will do for thinking.If people's expectations jibe closely with the actual benefits,then at least some of those improvements are probably a result of the placebo effect and not of exercise. For the new study,which was published last month in PLOS One,the researchers recruited 171 people through an online survey system,they asked half of these volunteers to estimate by how much a stretching and toning regimens performed three times a week might improve various measures of thinking.The other volunteers were asked the same questions,but about a regular walking program. In actual experiments,stretching and toning program generally have little if any impact on people's cognitive skills.Walking,on the other hand,seems to substantially improve thinking ability. But the survey respondents believed the opposite,estimating that the stretching and toning program would be more beneficial for the mind than walking.The estimates of benefits from walking were lower. These data,while they do not involve any actual exercise,are good news for people who do exercise."The results from our study suggest that the benefits of aerobic exercise are not a placebo effect,"...

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: What makes a person a scientist?Does he have ways or tools of learning that are different from those of others?The answer is "no". It isn't the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter .You will probably agree,too,that _ The scientist,however,goes one step further;he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works. The scientist's knowledge must be exact. There's no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein,who developed the Theory of Relativity,arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigation. Einstein's ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations. Question: What is the main idea of the passage? Options: A: Scientists are different from ordinary people. B: The Theory of Relativity. C: Exactness is the core of science. D: Exactness and way of using tools are the keys to making of a scientist.
