In an attempt to improve economic and social welfare of the people, the Hortland government has recently announced a scheme under which the government would provide certain staple foods at 30% discount to the authorized dealers. As the price of these staple foods will reduce, the low income consumers would surely be benefitted by the scheme.
Which of the following would be most useful to establish in evaluating the argument?
A. Whether discounting the staple prices is the only way to improve the economic and social welfare of the people?
B. Whether consumer with medium or high income groups would also be benefitted by the scheme?
C. Whether the discounted staples generate a significantly high demand in low income group?
D. Whether the prices that dealers charge for the staples will reflect the lower prices they would be paying the government.
E. Whether this scheme would have adverse impact on budgetary allocation of other initiative taken by the government.
Looking forward to a constructive discussion!

Thanks!
