【正确答案】The given line graph illustrates information on the number of overseas visitors traveling to Australia in millions of people. Overall, one notable trend seems to be that Australia has steadily become more popular as a destination spot. For example, there were 20 million more visitors to Australia in 2005 than in 1975. That's a jump from 10 million to 30 million in 20 years. The second table gives statistics showing the countries whose residents went to Australia between 1975 and 2005. In both years, the largest number of visitors came from Japan, followed by South Korea and Europe. Britain, the United States and China also had many people traveling to Australia in these years. In fact, the number of people visiting Australia grew in every one of these countries. For example, in 2005, 12 million people went there from Japan compared with only 3.2 million in 1975.
