How many really suffer as a result of labor market problems？ This is one of the most critical yet contentious social policy questions. In many ways, our social statistics exaggerate the degree of hardship.
Unemployment does not have the same dire consequences today as it did in the 1930's when most of the unemployed were primary breadwinners, when income and earnings were usually much closer to the margin of subsistence, and when there were no countervailing social programs for those failing in the labor market. Increasing affluence, the rise of families with more than one wage earner, the growing predominance of secondary earners among the unemployed, and improved social welfare protection have unquestionably mitigated the consequences of joblessness. Earnings and income data also overstate the dimensions of hardship. Among the millions with hourly earnings at or below the minimum wage level, the overwhelming majority are from multiple-earner, relatively affluent families. Most of those counted by the poverty statistics are elderly or handicapped or have family responsibilities which keep them out of the labor force, so the poverty statistics are by no means an accurate indicator of labor market pathologies.
Yet there are also many ways our social statistics underestimate the degree of labor-market- related hardship. The unemployment counts exclude the millions of fully employed workers whose wages are so low that their families remain in poverty. Low wages and repeated or prolonged unemployment frequently interact to undermine the capacity for self-support. Since the number experiencing joblessness at some time during the year is several times the number unemployed in any month, those who suffer as a result of forced idleness can equal or exceed average annual unemployment, even though only a minority of the jobless in any month really suffer. For every person counted in the monthly unemployment tallies, there is another working part-time because of the inability to find full-time work, or else outside the labor force but wanting a job. Finally, income transfers in our country have always focused on the elderly, disabled, and dependent, neglecting the needs of the working poor, so that the dramatic expansion of cash and in-kind transfers does not necessarily mean that those failing in the labor market are adequately protected.
As a result of such contradictory evidence, it is uncertain whether those suffering seriously as a result of thousands or the tens of millions, and, hence, whether high levels of joblessness can be tolerated or must be countered by job creation and economic stimulus. There is only one area of agreement in this debate--that the existing poverty, employment, and earnings statistics are inadequate for one of their primary applications, measuring the consequences of labor market problems.
Which of the following is the principal topic of the passage？ ______
A．What causes labor market pathologies that result in suffering.
B．Why income measures are imprecise in measuring degrees of poverty.
C．Which of the currently used statistical procedures are the best for estimating the incidence of hardship that is due to unemployment.
D．How social statistics give an unclear picture of the degree of hardship caused by tow wages and insufficient employment opportunities.

Have you ever noticed advertisements which say “Learn a foreign language in six weeks, or your money back! From the first day your pronunciation will be excellent.Just send...” and so on？ Of course, it never happens quite like that.The only language that is easy to learn is the mother tongue.Think how much practice that gets! Before the Second World War people usually learnt a foreign language in order to read the literature of the country.Now speaking a foreign language is what most people want.Every year many millions of people start learning one.

where it is spoken.However, most people cannot afford this, and for many it is not necessary.They need the language in order to do their work better.For example, scientists and doctors chiefly need to be able to read books and reports in the foreign language.Whether the language is learnt quickly or slowly, it is hard work.Machines and good books will help, but they cannot do the student's work for him.

It is often difficult for a man to be quite sure what tax ought to be paid to the government because it depends on so many different things: whether the man is married; how many children he has; whether he supports any relations; how much he earns; how much interest he receives; how much he has spent on his house during the year, and so on and so forth.All this makes it difficult to decide exactly how much the tax is.
There was a certain artist who was always very careful to pay the proper amount.
One year, after posting his check as usual, he began to wonder if he had paid enough, and after a lot of work, with a pencil and paper, he decided that he had not.He believed that he owed the government something.
He was just writing another check to send to the tax-collector when the postman dropped a letter into the box at the front door.Opening it, the artist was surprised to find inside it a check for five pounds from the tax-collector.The official explained that too much had been paid, and that therefore the difference was now returned to the taxpayer.
21.It is mentioned in the passage that one has to pay tax according to().
A.how much education one has received
