Final answer:
The organizational pattern requiring well-established or researched support is known as thesis-first or delayed-thesis, where the writer’s claim is either stated upfront or presented after considering the arguments.
Step-by-step explanation:
The organizational pattern that usually demands that speakers offer well-established or researched support is known as thesis-first or delayed-thesis organization. In a thesis-first approach, the writer’s position or claim on a debatable issue is presented upfront and supported throughout the text with credible evidence. The paper maintains this structure with relevant claims and evidence that reinforce the initial thesis.
In contrast, with a delayed-thesis organization, the writer introduces the issue and arguments first, then presents the thesis later in the essay. This method shows readers that the writer is weighing the evidence carefully before stating a position. Whichever pattern is chosen, well-researched support is essential to establish the claims and engage the audience effectively.
