The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The Open Door policy attempted to preserve the chances for American businesses to enter which markets?
Answer: in the market of Asia, specifically, in China.
At the end of the 1800s and the beginning of the 1900s, the United States wanted to improve its trade relationships with Asian countries, especially with China. The United States knew that some European nations had some previous trade relations with this country and had some kind of preferences. The United States federal government did not want to be left behind in trade with China, and that is why it formulated the Open Door Policy to close good deals and improve trade with China.
The Information Revolution is a phrase we use to refer to the dramatic changes taking place during the last half of the 20th century in which service jobs (ranging from high technology, highly skilled professions to low-skill jobs like short-order cook) are more common than jobs in manufacturing or agriculture. The product of skilled professionals is the information or knowledge they provide.
The information revolution began with the invention of the integrated circuit or computer chip. Those chips have revolutionized our lives, running our appliances, providing calculators, computers, and other electronic devices to control our world.
It is still early enough that no one knows precisely what all of the implications of the information revolution will be for social life. But clearly changes such as the information superhighway permitting people to communicate using computers all around the globe, fax machines, satellite dishes, and cellular phones are changing how families spend their time, the kind of work we do, and many other aspects of our lives.
Hope this helps ^^
