Manufacturers of mechanical pencils make most of the 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 new 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?Write’s problem is that its leads are pricier than competitors’, so people avoid them. The plan is to “lock in” customers by making a pencil that only takes Write leads, at the same (still not cheap) price. This will increase lead sales only if many people will actually buy and use this new pencil. The best support is evidence that the new pencil will be chosen by users.
(A) First-time buyers of mechanical pencils tend to buy the least expensive mechanical pencils available.
This weakens the plan. If Write’s pencil is not the cheapest, first-time buyers may avoid it, reducing the number of locked-in users and thus reducing lead sales.
(B) Annual sales of mechanical pencils are expected to triple over the next five years.
This is a general market growth claim. It does not show Write will capture those buyers, so it only weakly supports increased Write lead sales.
(C) A Write Company executive is studying ways to reduce the cost of manufacturing pencil leads.
Studying does not mean costs will drop, and the plan explicitly keeps the lead price the same anyway. So it does not support the projection.
(D) A rival manufacturer recently announced similar plans to introduce a mechanical pencil that would accept only the leads produced by that manufacturer.
This does not support Write. If anything, it suggests competitors may also lock in customers, which could make it harder for Write to increase its lead sales.
(E) In extensive test marketing, mechanical-pencil users found the new Write Company pencil markedly superior to other mechanical pencils they had used.
This directly supports the projection: if users strongly prefer the new pencil, more people will buy it, and once they own it they must buy Write leads. That is the clearest reason lead sales would increase.
