Q13的小短文:So why do companies spend so much on price promotions?Clearly price promotions are generally run at a loss, otherwise there would be more of them.And the bigger the increase in sales at promotion prices, the bigger the loss.While short-term price promotions can have legitimate uses, such as reducing excess inventory, it is the recognizable increase in sales that is their main attraction to management, which is therefore reluctant to abandon this strategy despite its effect on the bottom line.Q13:The passage suggests that evidence for price promotions’ “effect on the bottom line” (line 40) is provided by
A.the lack of lingering aftereffects from price promotions
B.the frequency with which price promotions occur
C.price promotions’ inability to attract new customers
D.price promotions’ recognizable effect on sales
E.the legitimate uses to which management can put price promotions
Q22：Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides.New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt.Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.
In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT: A.What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?
B.To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?
C.What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
D.How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?
E.Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?
