Since this is a history question, I must be wrong to get a C. Pay attention to the time. 1960, China entered the adjustment period. The people's commune of the Great Leap Forward produced so much, of course, it can't be produced any more.

Moreover, I think that the compression is commodity expenditure, so it is to reduce national expenditure, of course, to reduce market pressure.

The quality of the products produced at that time was not very good, and the demand was already in short supply. The state reduced expenditure only to ease the pressure of market supply.
