Manufacturers of mechanical pencils make most of their profit on pencil leads rather than on the pencils themselves. The Write Company, which cannot sell its leads as cheaply as other manufacturers can, plans to alter the design of its mechanical pencil so that it will accept only a newly designed Write Company lead, which will be sold at the same price as the Write Company's current lead.
Which of the following, if true, most strongly supports the Write Company's projection that its plan will lead to an increase in its sales of pencil leads?
The new Write Company pencil will be introduced at a price higher than the price the Write Company charges for its current model.
In the foreseeable future, manufacturers of mechanical pencils will probably have to raise the prices they charge for mechanical pencils.
The newly designed Write Company lead will cost somewhat more to manufacture than the Write Company's current lead does.
A rival manufacturer recently announced similar plans to introduce a mechanical pencil that would accept only the leads produced by that manufacturer.
In extensive test marketing, mechanical-pencil users found the new Write Company pencil markedly superior to other mechanical pencils they had used.
