I think it’s______ the field of my study.

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 utilization of a decision worksheet. Psychologists who study optimization compare the actual decisions 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 pertinent considerations that will be affected by each decision are listed, and the relative importance of each consideration or consequence is determined. Each consideration is assigned a numerical value to reflect its relative 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 sill 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 succinct 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 goals because long-range goals often involve a different decision than short range ones. Focusing on long-range goals, a graduating student might revise the question above to "What will I do after graduation that will lead to successful career?"

What does the passage mainly discuss?

A．A method to assist in making complex decisions.

B．A comparison of actual decisions and ideal decisions.

C．Research on how people make decisions.

D．Differences between long-range and short-range decision making.

A、Mathematics

B、English

C、Science

D、Geography

We might marvel at the progress made in every field of study, but the methods of testing a person's knowledge and ability remain as primitive as ever they were. It really is extraordinary that after all these years, educationists have still failed to device anything more efficient and reliable than examinations. For all the pious claim that examinations text what you know, it is common knowledge that they more often do the exact opposite. They may be a good means of testing memory, or the knack of working rapidly under extreme pressure, but they can tell you nothing about a person's true ability and aptitude.

As anxiety-makers, examinations are second to none. That is because so much depends oil them. They are the mark of success of failure in our society. Your whole future may be decided in one fateful day. It doesn't matter that you weren't feeling very well, or that your mother died. Little things like that don't count: the exam goes on. No one can give of his best when he is in mortal terror, or after a sleepless night, yet this is precisely what the examination system expects him to do. The moment a child begins school, he enters a world of vicious competition where success and failure are clearly defined and measured. Can we wonder at the increasing number of "drop outs": young people who are written off as utter failures before they have even embarked on a career? Can we be surprised at the suicide rate among students?

A good education should, among other things, train you to think for yourself. The examination system does anything but that. What has to be learnt is rigidly laid down by a syllabus, so the student is encouraged to memorize. Examinations do not motivate a student to read widely, but to restrict his reading; they do not enable him to seek more and more knowledge, but induce cramming. They lower the standards of teaching, for they deprive the teacher of all freedoms. Teachers themselves arc often judged by examination results and instead of teaching their subjects, they are reduced to training their students in exam techniques which they despise. The most successful candidates are not always the best educated; they are the best trained in the technique of working under duress.

The results on which so much depends are often nothing more than a subjective assessment by some anonymous examiner. Examiners are only human. They get tired and hungry; they make mistakes. Yet they have to mark stacks of hastily scrawled scripts in a limited amount of time. They work under the same sort of pressure as the candidates. And their word carries weight. After a judge's decision you have the right Of appeal, but not after an examiner's. There must surely be many simpler and more effective ways of assessing a person's true abilities. Is it cynical to suggest that examinations are merely a profitable business for the institutions that run them? This is what it boils down to in the last analysis. The best comment on the system is this illiterate message recently scrawled on a wall: I were a teenage drop-out and now I are a teenage millionaire.

The main idea of this passage is ______.

A．examinations exert a pernicious influence on education

B．examinations are ineffective

C．examinations are profitable for institutions

D．examinations are a burden on students

A study in Florida that stated that the death penalty was given in 19 out of 151 cases in which a white killed a white, in 0 out of 9 cases in which a white killed a black, in 11 out of 63 cases in which a black killed a white, and in 6 out of 103 cases in which a black killed a black. The table shows results of ?tting a logit model for death penalty as the response (1=yes), with defendant’s race (1=white) and victims’ race (1=white) as indicator predictors.a. Based on the parameter estimates, which group is most likely to have the “yes” response? Estimate the probability in that case. b. Interpret the parameter estimate for victim’s race. c. Using information shown, construct and interpret a 95% likelihood-ratio con?dence interval for the conditional odds ratio between the death penalty verdict and victim’s race. d. Test the effect of victim’s race, controlling for defendant’s race, using a Wald test or likelihood-ratio test. Interpret.
