When Emily Beardmore first heard that a trip was being planned by the biology class at Windsor High School, she thought about how much fun it would be.

“I thought it would be a really good experience to go with other friends and teachers to another country in an environment other than a vacation environment,” the 17-year-old girl said.

A few months later, Emily got her chance when she and 14 of her classmates, along with biology teacher Tamara Pennington went to Costa Rica for eight days in late May.

“It was not just a tour,” said Pennington, who organized the trip. “You can go any place in the world on just a tour. This one was really working with the sea turtles (海龟) and practicing conservation(保护). It just seemed like the perfect science field trip for kids who think they want to get into science to see what it's really like to be out in the field and enjoy themselves.”

Emily said her time on the turtle program, which was the focus of the trip, was “crazy.”“We were walking on the beach at night and you can’t see anything—just see a big black dot.” She said with a laugh. “I was not expecting the turtles to be that big.” The turtles are leatherback turtles, which are becoming extinct (灭绝) because their eggs are used as food.

“When they would move their legs while laying their eggs they were really hard to control because they were a lot more powerful than you would imagine,” Emily said.

Once the eggs were collected, the students took them back to a hatchery(孵化场) and dug holes to copy the hole the mother turtle had made and then buried the eggs for the 60 days needed to hatch.

“The experience was so cool,” Emily said. “You go to another country to see what their culture is like and learn what their everyday lives are like. It made me really want to help out my mom a lot more than I do, and value what I have.”

The differences in living standards around the world are vast In 1993, the average American had an income of about ＄25,000. In the same year, the average Mexican earned $7,000, and the average Nigerian earned. ＄1,500. Not surprisingly, this large variation in average income is reflected in various measures of the quality of life. Changes in living standards over time are also large. In the United States, incomes have historically grown about 2 percent per year (after adjusting for changes in the cost of living). At this rate, average income doubles every 35 years. In some countries, economic growth has been even more rapid. In Japan, for instance, average income has doubled in the past 20 years, and in South Korea it has doubled in the past 10 years.

What explains these large differences in living standards among countries and over time The answer is surprisingly simple. Almost all variation in living standards is attributable to differences in countries’ productivity—hat is, the amount of goods and services produced from each hour of a worker’s time. In nations where workers can produce a large quantity of goods and services per unit of time, most people enjoy a high standard of living; in nations where workers are less productive, most people must endure a more meager existence. Similarly, the growth rate of a nation’s productivity determines the growth rate of its average income.

The fundamental relationship between productivity and living standards is simple, but its implications are far-reaching. If productivity is the primary determinant of living standards, other explanations must be of secondary importance. For example, people might think that labor unions or minimum-wage laws contributed to the rise in living standards of American workers over the past century. Yet the real hero of American workers is their rising productivity.

The relationship between productivity and living standards also has great implications for public policy. When thinking about how any policy will affect living standards, the key question is how it will affect our ability to produce goods and services. To improve living standards, policymakers need to raise productivity by ensuring that workers are well educated, have the tools needed to produce goods and services, and have access to the best available technology.

What is the most important factor that leads to the rise in living standards of average people().

A. Labor unions.

B. Minimum-wage laws.

C. Rising productivity.

D. Favorable public policy.
