There have been newspapers and magazines that unrealistically advertised a people's commune's wheat yield of 65438+100000 Jin and Chinese cabbage of 250 Jin, and even put forward that "how much people are bold, how much will be produced on the ground". D

Test analysis: This question mainly examines students' accurate understanding of the Great Leap Forward. In the materials, "the yield of wheat per mu is 65438+100000 Jin, and that of a cabbage is 250 Jin" and "how bold people are and how high the land is" embodies the grandiose style, exaggerates people's subjective initiative, conforms to the characteristics of the Great Leap Forward, D meets the meaning of the question, while AC correctly explores the development of socialism, and B has nothing to do with the meaning of the question, so D is chosen.
