Question: Article: Researchers in the field of psychology have found that one of the best ways to make an important decision, such as choosing a university to attend or a business to invest in, involves the use of a decision worksheet. Psychologists who study optimization compare the actual decision made by people to theoretical ideal decisions to see how similar they are. Proponents of the worksheet procedure believe that it will yield optimal, that is, the best decisions. Although there are several variations on the exact format that worksheets can take, they are all similar in their essential aspects. Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem. Next, the relevant considerations that will be affected by each decision are listed, and the importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its importance. A decision is mathematically calculated by adding these values together. The alternative with the highest number of points emerges as the best decision. Since most important problems are multifaceted ,there are several alternatives to choose from, each with unique advantages and disadvantages. One of the benefits of a pencil and paper decision-making procedure is that it permits people to deal with more variables than their minds can generally comprehend and remember. On the average, people can keep about seven ideas in their minds at once. A worksheet can be especially useful when the decision involves a large number of variables with complex relationships. A realistic example for many college students is the question "What will I do after graduation?" A graduate might seek a position that offers specialized training, pursue an advanced degree, or travel abroad for a year. A decision-making worksheet begins with a concise statement of the problem that will also help to narrow it. It is important to be clear about the distinction between long-range and immediate... Question: The author states that "On the average, people can keep about seven ideas in their minds at once" to explain that _ . Yes or no, is the answer "human mental capacity has limitations"?
Answer: No

Question: Article: All too often, a choice that seems sustainable turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol for fuel from corn. Corn is a renewable resource --you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that's not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land -including, in some cases, rain forest in places such as Brazil--into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that _ might not help. You cannot really declare any practice "sustainable" until you have done a complete life-cycle analysis of its environmental costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis. Question: What might directly cause the loss of the forest according to the text? Yes or no, is the answer "The greater need for farmland"?
Answer: No

Question: Article: Most people think of racing when they see greyhounds and believe they need lots of exercise. They can actually be quite lazy! Greyhounds are good at fast races but not long-distance running. They do need regular exercise but they like to run for a short burst and then get back on the bed or a comfortable seat. Another misunderstanding is that greyhounds must be aggressive because they are big in size. In fact greyhounds love people and are gentle with children. Greyhounds can live for 12 - 14 years but usually only race for two or three years, and after that they make great pets. They don't need a lot of space, don't make a lot of noise, and don't eat a lot for their size. Normally, greyhounds can be as tall as 90 cm. There is, however, a small-sized greyhound, which stands only 33 cm. Greyhounds come in a variety of colors. Grey and yellowish-brown are the most common. Others include black, white, blue, red and brown or a mix of these. Greyhounds have smooth body coats, low body fat and are very healthy. Because they're slim they don't have the leg problems like other dogs the same height . But they do feel the cold, especially since they would much rather be at home in bed than walking around outside. Question: Why does the author say that greyhounds make great pets? Yes or no, is the answer "They are quiet and easy to look after."?
Answer:
No
