Poetry journal patron: Everybody who publishes in The Brick Wall Review has to agree in advance that if a poem is printed in one of its regular issues, the magazine also has the right to reprint it, without monetary compensation, in its annual anthology.
Evidence
The Brick Wall Review makes enough money from sales of its anthologies to cover most operating expenses.
Most poems published in your magazine are very similar to those published in The Brick Wall Review.
Conclusion
So, if your magazine also published an anthology of poems first printed in your magazine, you could depend less on donations.
Evaluate
Given that ... The BWR makes enough from its anthology to cover operating expenses,
How could we argue that ... if our magazine copied BWR's idea and published an anthology of poems first printed in our magazine, it wouldn't help us raise money (which would make us less dependent on donations?
The argument assumes that what is true for the Brick Wall Review will also be true for the magazine under discussion. We need a way to argue that even though this anthology has been a successful revenue raising plan for Brick Wall Review, it wouldn't be for our magazine.
The only similarity the argument has established is that our poems are similar to their poems. But maybe their marketing team is better. Maybe their readership is more interested in anthologies. Maybe buying a copy of the anthology is required to see one of the poets give a live reading.
If there's something that makes this plan a success for BWR that we wouldn't necessarily be able to do if we were doing an anthology, then that weakens the assumption that we will see similar success from this plan.
Goal
Look for answer that would help us to argue that .
