Which of the following most logically completes the argument?
Farmers producing cotton have found that by feeding an iron-based pigment through the irrigation system of a field, the color of the cotton fibers can be altered. Since most textile manufacturers prefer having complete control over the coloration of the cotton products they produce, no interest has been shown in cotton that has been pigmented in this way. However, it is likely that the method will be implemented because __________.
Incorrect.
[[snippet]]This answer choice neither strengthens nor weakens the conclusion and, therefore, cannot logically complete the argument. Since textile manufacturers are not interested in the pigmented cotton, there is no reason to believe that the method will generate income for the farmers.
Incorrect.
[[snippet]]This answer choice weakens the conclusion and therefore cannot logically complete the argument. The blockage and corrosion mentioned in this statement are major reasons why the new method will not be used.
Incorrect.
[[snippet]]This answer choice neither strengthens nor weakens the conclusion and, therefore, cannot logically complete the argument. The argument does not deal with irrigation systems in general, or their advantages.
Incorrect.
[[snippet]]This answer choice neither strengthens nor weakens the conclusion and, therefore, cannot logically complete the argument. The only mention of textile manufacturers is made in order to tell us that they are not interested in pigmented cotton. Since the new method deals with color and not quality or quantity, this answer choice holds no relevance.
Superb work!
[[snippet]]This answer choice strengthens the conclusion and therefore logically completes the argument. If using the method with a white pigment makes the cotton stronger (more resilient) without affecting its color, then it is more likely to be implemented.
