The world's population is more mobile today than ever before. In 2010, more than 200 million people left their home countries to live in a new country. This is about 3 percent of the total world population. Some experts believe that number will swell to 400 million by 2050. Rates of immigration have remained strong for the last 300 years, but patterns of immigration have changed since World War II. The backgrounds and experiences of today's immigrants are different from those of the typical European immigrant of the nineteenth and early twentieth centuries. Contemporary immigrants range from unskilled laborers to highly skilled professionals, and they come from and go to countries all over the world. In the nineteenth century and until World War II, immigration was primarily in one direction- from the Old World to the New World. This is no longer the case. Countries such as Russia and China, which have long been, and continue to be, significant source countries, are now also destination countries. There is also considerable mobility inside regions, such as from one European country to another, or among the countries of the former Soviet Union. In spite of such differences, the push and pull factors for immigration remain essentially the same as they were 100 years ago. Most people move to another country because they want a better life. For the majority of immigrants, this means better economic conditions. As in past generations, a labor shortage in one country often draws workers from another country, especially if wages are significantly higher. In some small countries, for example, Qatar, United Arab Emirates, and Kuwait, there are more jobs than citizens. The demand for labor is so high that the majority of the population consists of foreign-born workers, ranging from highly skilled engineers and financial experts to domestic and construction workers. In traditional destination countries, such as the United States, however, labor needs have changed. Today, although there is still demand for unskilled... Which is not the factor contributing to the immigration? A) Education B) Political instability C) Religious freedom D) Family and community connections

Q: Goats are being hired to do the work of men in a neighborhood just outside of San Diego. The fires that occurred in Hillborough four years ago destroyed thirty homes, most of which have been rebuilt. While the home were rebuilt, the grasses, bushes, and shrubs were re-growing. The area is now so overgrown in brush that it again brings a major danger of fire. The city government asked for bids to remove the brush. The lowest bid they received was $50,000. And that was if the city provided breakfast and lunch for the work crews for the six weeks it would take to clear the overgrown area. The city government said no, offering unlimited coffee and a doughnut a day for each crew member. When that offer was rejected, the city asked for help on its website. A sheepherder in Montana and a goat-herder in San Bernardino read about the city's problem while surfing the web on their laptops. They both offered to do the job for $25,000. The government chose the goat-herder because he lived closer. When told that the city dump was overflowing, the goat-herder said, "No problem. My goats will eat everything in your dump. Except for the automobile engines, of course." So, for another $5,000, the city killed two birds with one stone. If all goes well, they will invite the goat-herder and his "family" back every three years. The goat-herder said he will probably visit San Diego while his goats are in the dump. "I want to go there by plane; I just hope we don't crash. My goats would miss me a lot," he said. The city government rejected the $50,000 bid because _ . A) it thought that the price for removing the brush was too high B) it expected for better help on its website C) it thought that coffee and doughnuts were the best things for the work crews. D) it didn't want to supply breakfast and lunch for the work crews.
