Section C
Directions: Read the following passage and choose the most suitable heading from A-F for each paragraph.  There is one extra heading which you do not need.
（D）
A. Value of rare skills
B. Dangerous jobs paid more
C. Social demand decides reward
D. Developing skills
E. Women’s skills rewarded
F. Reason for taking low-paying jobs
1.     
The rewards of a skill that is in strictly limited supply depend upon the demand for that skill. Men’s professional basketball is extremely popular, and the top NBA players make millions of dollars per year. There are some great women basketball players, too, but because women’s professional basketball has not bee popular, these women’s skills go paratively unrewarded.
2.     
Some people with very rare skills can make enormous salaries in a free market economy. Paula Abdel has a voice that millions of people are willing to pay to hear in person, and on tapes, CDs, records, and videos. Before Pablo Picasso died, he could sell small sketches for vast sums of money. Were they worth it? They were worth exactly what the highest bidder (出价人) was willing to pay.
3.     
Not all skills are inborn, however. Some people have invested in training and schooling to improve their knowledge and skills. When we go to school, we are investing in human capital that we expect to yield dividends, partly in the form of higher wages, later on. Human capital is also produced through on-the-job training.
4.     
Some jobs are more desirable than others. Entry-level positions in attractive industries such as publishing and television tend to be low-paying. Since talented people are willing to take entry-level jobs in these industries at salaries below what they could earn in other occupations, there must be other, non-wage rewards. It may be that the job itself is more personally rewarding, or that a low-paying apprenticeship is the only way to acquire the human capital necessary to advance.
5.     
On the other hand, pensating differentials are required when an occupation is very dangerous. Workers on skyscrapers and bridges mand additional wages. Fire fighters in cities that have many old, run-down buildings are usually paid more than those in relatively tranquil rural or suburban areas.
