Problem: Please answer a question about the following article about Korean War:
After the formation of the People's Republic of China in 1949, the Chinese government named the Western nations, led by the United States, as the biggest threat to its national security. Basing this judgment on China's century of humiliation beginning in the early 19th century, American support for the Nationalists during the Chinese Civil War, and the ideological struggles between revolutionaries and reactionaries, the Chinese leadership believed that China would become a critical battleground in the United States' crusade against Communism. As a countermeasure and to elevate China's standing among the worldwide Communist movements, the Chinese leadership adopted a foreign policy that actively promoted Communist revolutions throughout territories on China's periphery.
To show their strength in the international Communist movement, what did China do?
A: promoted Communist revolutions
Problem: Please answer a question about the following article about Raleigh, North Carolina:
North Carolina Museum of Art, occupying a large suburban campus on Blue Ridge Road near the North Carolina State Fairgrounds, maintains one of the premier public art collections located between Washington, D.C., and Atlanta. In addition to its extensive collections of American Art, European Art and ancient art, the museum recently has hosted major exhibitions featuring Auguste Rodin (in 2000) and Claude Monet (in 2006-07), each attracting more than 200,000 visitors. Unlike most prominent public museums, the North Carolina Museum of Art acquired a large number of the works in its permanent collection through purchases with public funds. The museum's outdoor park is one of the largest such art parks in the country. The museum facility underwent a major expansion which greatly expanded the exhibit space that was completed in 2010. The 127,000 sf new expansion is designed by NYC architect Thomas Phifer and Partners.
How did the museum get the artworks they have?
A: public funds

Problem: Please answer a question about the following article about MP3:
Besides the bit rate of an encoded piece of audio, the quality of MP3 files also depends on the quality of the encoder itself, and the difficulty of the signal being encoded. As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders may feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two different MP3 encoders at about 128 kbit/s, one scored 3.66 on a 1–5 scale, while the other scored only 2.22.
To compare qualities, sound files are evaluated on a scale that ranges from 1 to what?
A:
5
