The answer D is obviously wrong. The household contract responsibility system was implemented nationwide in the early 1980s, and its predecessor was 1978' s policy of "unified contracting and unified distribution" in Xiaogang Village, Fengyang, Anhui Province. The topic phenomenon occurred in 1976, so the household contract responsibility system has not been implemented at this time, so it is wrong to choose D.A. The people's commune movement was carried out in 1958, so 1976 is almost late. C the answer can be ruled out immediately. Therefore, the correct answer is B. The people's commune movement violates the objective law of economic development and seriously dampens the enthusiasm of workers, so the phenomenon in the question will inevitably appear!
