The death of slavery also ended the plantation system. The number of farms doubled from 1860 to 1880, but the number of landowners remained the same. The size of the average farm dropped by more than half, as sharecropping and tenancy rose. A shortage of cash forced Southern farmers to borrow against future crops. Crop liens and high credit costs kept a lot of black and white farmers trapped in a cycle of debt and poverty. So at the very time the rest of the economy was consolidating after the Civil War, Southern agriculture was marching off in the opposite, less efficient direction. Which sentence is main idea?

Educational psychologist Benjamin Bloom did a study of high achievers and found that drive and determination, not great natural talent, led to their success. The study included America's top performers in six fields: concert pianist, Olympic swimmers, sculptors, tennis players, mathematicians, and research neurologists. Development of Bloom's subjects began when parents exposed the child to music, swimming, scientific ideas, and so forth, "just for fun." At first many of the children were quite ordinary in their skills. One Olympic swimmer, for instance, remembers repeatedly losing races as a ten-year-old. At some point, however, the children began to get recognition for their abilities and pursued them more actively. After more successes and encouragement, the youngsters began "living" for their talent. Most spent many hours each day practicing their skills. This continued for many years before they reached truly extraordinary heights of achievement.

But psychologists have identified a number of secondary drives that are also extremely powerful forces. One such secondary drive is the need for achievement. Most of us are motivated by the satisfaction of striving for and attaining a level of excellence in our chosen endeavors. Another powerful secondary drive is the need for affiliation. Put simply, this is the widespread human need for friendship. A third type of secondary drive is the need for power. Some people are very much influenced by their need to have an impact on those around them. Which sentence is main idea?

The company finally learned that Spanish speakers read the car's name as the Spanish phrase "no va," meaning "doesn't go"! Like Chevrolet, many American companies have learned the hard way that they need to know their customers' language. When Pepsi-Cola ran its "Come Alive with Pepsi" ads in China, the consumers laughed. The company had not translated its slogan quite right. In Chinese, it came out as "Pepsi brings your ancestors back from the dead." Which sentence is main idea?
