Passage 3

Bernard Jackson is a free man today, but he has many bitter memories. Jackson spent five years in prison after a jury wrongly convicted him of raping two women. At Jackson's trial, although two witnesses testified that Jackson was with them in another location at the times of the crimes, he was convicted anyway. Why? The jury believed the testimony of the two victims, who positively identified Jackson as the man who has attacked them. The court eventually freed Jackson after the police found the man who had really committed the crimes. Jackson was similar in appearance to the guilty man. The two women has made a mistake in identity. As a result, Jackson has lost five years of his life.

The two women in this case were eyewitnesses. They clearly saw the man who attacked them, yet they mistakenly identified an innocent person. Similar incidents have occurred before. Eyewitnesses to other crimes have identified the wrong person in a police lineup or in photographs.

Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a lineup of people. They can become confused by seeing many photographs or similar faces. The number of people in the lineup, and whether it is a live lineup or a photograph, may also affect a witness's decision. People sometimes have difficulty identifying people of other races. The questions the police ask witnesses also have an effect on them.

Question 33: What do we learn about Bernard Jackson?

Question 34: What led directly to Jackson’s sentence?

Question 35: What lesson do we learn from Jackson’s case?

About 700,000 children in Mexico dropped out of school last year as recession-stricken families pushed kids to work, and a weak economic recovery will allow only slight improvement in the drop-out rate in 2010, a top education official said.

Mexico's economy suffered more than any other in Latin America last year, shrinking an estimated 7 percent due to a plunge in U.S. demand for Mexican exports such as cars.

The decline led to a 4 percent increase in the number of kids who left primary or middle school in 2009, said Juan de Dios Castro, who heads the nation's adult education program and keeps a close watch on drop-out rates.

"Poverty rose and that is a factor that makes our job more difficult," Castro told Reuters in an interview earlier this month.

Hindered by higher taxes and weak demand for its exports, Mexico's economy is seen only partially recovering this year. As a result, drop-out rates will not improve much, Castro said.

"There will be some improvement, but not significant," Castro said.

Mexicohas historically had high drop-out rates as poor families pull kids out of school to help put food on the table, and children often sell candy and crafts in the streets or work in restaurants.

The nation's drop-out problem is just the latest bad news for the long-term competitiveness of the Mexican economy. Mexico's politicians have resisted mending the country's tax, energy and labor laws for decades, leaving its economy behind countries such as Brazil and Chile.
