IMO-DPoint to note:-
Company X now has a
monopoly in this particular branch of industry and therefore will
probably raise the price of its cardboard containersi.e.
Monopoly---lead to ----Price Increase Which of the following statements, if true, would most seriously
weaken the claim made above?
(A) An
increase in the price of cardboard containers would not necessarily increase the retail price of items packed in these containers. ----Incorrect--talks about only one aspect i.e price increase....
(B) The cost of lumber is a major
determinant of the cost of cardboard containers-- Incorrect--Its a major determinant but that doesn't say anything about price increase.
(C) There has been a recent increase in demand for cardboard containers. ---Incorrect---Demand lead to price increase may not be true....
(D) Manufacturers of cardboard containers face increasingly stiff competition from manufacturers of plastic containers.
--Correct--- Monopoly not there as there are competitors...
(E) Before Company X bought Company Y, Company X had consistently set the prices of its cardboard containers below the prices set by Y.....Incorrect--Just because prices set were lower doesnt give a reason that price go up , it can be one of the reason but not necessary..
