Harry Trevalga: You and your publication have unfairly discriminated against my poems.
Main Conclusion
Our policy and practice is perfectly fair.
Intermediate Conclusion (hence)
The judge can't possibly know who wrote the poems.
Evidence
The judge never sees the name of the poet whose poem she is reading.
Evaluate
Since there are two reasoning moves, we can scrutinize both.
We have a missing link of, , and one of .
Goal
Those missing links could themselves be the answers, but otherwise the answer might rule out an idea that would object to those assumption.
Like maybe you can't see the name, but you can still figure out who wrote the poem some other way (writing style? stationery? it smells like their cologne)
Or maybe the judge doesn't know who wrote each poem, but the practice still isn't fair (because she always decides to just choose the first three poems she reads)
