Understanding the argument -
Conclusion - The kitchen can collect its licensing fees without endangering its other revenues. Oh wait? what is this other revenue? This is the revenue that Kitchen magazine gets from other advertisements. Okay, so it says, "The kitchen can collect licensing fees without hampering the revenues from other cookware companies. Interesting.
Basis of conclusion? Because - experts have evaluated the cookware and found it superior to all other cookware advertised in the Kitchen.
What can weaken the argument- what if other companies don't like the brand name to be associated with one cookware and they pull out? So we have to guard the argument against such weakener.
Option elimination -
(A) No other line of cookware is superior to that which will carry the Kitchen name. - At best, it's a strengthener. But will it be an assumption? Let's negate it. But remember, we have to respect the facts in the argument. Okay, back to our negation. Another line of cookware is superior to that which will carry the Kitchen name. So we said to respect the facts. This is not compared with the products in the Kitchen; it's comparing with products other than Kitchen. We don't know the customer's response to this product compared to other products outside of Kitchen. So, the conclusion is still valid. We need an assumption whose negation will shatter the conclusion.
(B) Kitchen will not license the use of its name for any products other than the line of cookware. - out of scope.
(C) Makers of cookware will not find Kitchen a less attractive advertising vehicle because the magazine's name is associated with a competing product. Ok.
(D) Consumers who are not regular readers of Kitchen magazine will be attracted to the cookware by the Kitchen name. - Strengthener
(E) Kitchen is one of the most prestigious cooking-related magazines. - But this doesn't talk about licensing revenue/other revenue? No. Out of scope.
