Which one of the following is an assumption on which the argument depends?
(A) Certain kinds of paper cannot be manufactured from recycled paper.
(B) The fillers that are used to make paper white are harmful to the environment.
(C) Grayish writing paper will not be a universally acceptable alternative to white writing paper.
(D) Beyond a certain limit, increasing the amount of filler added to paper pulp does not increase the whiteness of the paper made from the pulp.
(E) The total amount of writing paper manufactured worldwide will increase significantly in the future.
Imo C
Premise 1: Manufacturers of writing paper need to add mineral “filler” to paper pulp if the paper made from the pulp is to look white
Premise 2: Without such filler, paper products look grayish.
Premise 3: To make writing paper that looks white from recycled paper requires more filler than is required to make such paper from other sources.
Conclusion: Therefore, barring the more efficient use of fillers in paper manufacturing or the development of paper-whitening technologies that do not require mineral fillers, if writing paper made from recycled paper comes to replace other types of writing paper,paper manufacturers will have to use more filler than they now use.
Now the conclusion is pretty much a leap from the premises mentioned above.
More recycled paper will be used then more filler will be used and other types of paper are replaced by recycled paper.
The conclusion is pretty simple but it is making a pretty bold claim that recycled paper would be used and that they would required more filler.
No if the government mandates that the paper quality would be compromised keeping environment in mind and recycled paper would be the norm without the filler.
So the conclusion falls apart. So this is the assumption required.
A Well this true bbut this not our assumption
B This may be true but it is not relevant to he argument.
C correct.
D But what if they consume a lot of filler before reaching saturation anyways this is also out of scope.
E Out of scope.
