Correct Option EPharaphasing: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 (led to save cost)
- use to yield a crop fertilizer (result from this use)
- leaving a relatively small volume of waste for disposal (in consequence)
Argument: Replacing the common salt with Potassium chloride will increase the profit and adhere environmental regulation for TANCO
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?
Wrong
Strenghten - if cost of saving and earning is more from potassium choride, then it has advantages to shift.
It can impact the company profits
(B) To what extent is
the equipment involved in preserving animal hides using common salt suitable for
preserving animal hides using potassium chloride?
wrong
Strengthen - if same equipement is used, again profitable, if any other equipement is needed, then additional cost involved and its returns needs to be calculated.
It can impact the company profits
(C) What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?
Wrong -
Strengthen - it is already mentioned in the passage and usage of potassium chloride will be useful, it can gain profit or non usage can lead to loss.
It can impact the company profits.
(D) How closely does
leather those results (quality)
when common salt is used to preserve hides resemble that which results
when potassium chloride is used?
Wrong -
Strenghten - leather quality will play a important role, money saved by usage of potassium chloride can improve, remain still or reduce need to be caluclated- It can impact the company profits
(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?
Correct :
Weaken: Technically common salt involves sodium and Potassium chloride salt has potassium, both are "SALT"
and salt are used to preseving animal hides, hence it will be waste of research to do about SALT properties to another SALT properties
