Some of the following factors have the potential to influence the demand or quantity demanded of unskilled labor. Influences on the supply or quantity supplied may also result. Holding all else equal, describe these influences as increasing or decreasing, and indicate the direction of the resulting movement along or shift in the relevant curve(s).

B. A rise in welfare benefits.

C. An increase in the popularity of self-service gas stations, car washes, and so on.
