This question is incomplete because the main quotation is not given. I searched for the complete question and I found it. The complete question is:
Who are our enemies? Who are our friends? These are the most important questions we must ask ourselves if the revolution is to succeed. . . .
If we are to distinguish real friends from real enemies, we must study and analyze the class structure of Chinese society. . . . The landowners are the most backward and the most intolerant of progress in China. . . . Their existence is completely incompatible with the goals of the Chinese revolution.
—Mao Zedong,
Analysis of the Classes in Chinese Society
Which statement best summarizes this quotation?
The correct answer is C. The climate is harsh, which limits the number of species that can live there.
Explanation
The text is a fragment of a speech by Mao Zedong, a Chinese revolutionary leader of communist ideology who led the revolution in China during 1949. His revolutionary ideas proposed to protect the Chinese working class, especially the peasants. Therefore, in his speech he points to the landlords by saying that "The landowners are the most backward and the most intolerant of progress in China .... Their existence is completely incompatible with the goals of the Chinese revolution." because they had a lot of lands that they did not use, while some peasants had to pay for land to work. From the above, it can be inferred that the sentence that best summarizes the purpose of Mao Zedong's speech is A. The biggest enemies of the revolution are the landlords.
