6.B Placing a Sentence Where the Reasoning Needs It

A paragraph is not a pile of true sentences, it is a chain of claims where each link depends on the one before it. A sentence can be factually perfect and still wreck the paragraph if it lands in the wrong slot, because the words inside it are built to point at something specific that has to already exist on the page. Readers don't just process meaning, they track reference: a pronoun or demonstrative like 'this', 'that', 'these', or a repeated key term is a hook, and the hook only reaches backward to whatever antecedent it was built for. Put the sentence before that antecedent, or too many sentences after it, and the hook grabs nothing, or grabs the wrong thing.

This is why placement is a reasoning problem, not a style problem. A smooth-sounding transplant can still be illegal if it severs a cause from its effect or drops evidence after the conclusion it was supposed to support, since a reason offered after the claim it backs has already been skipped by the reader's logic. The test for a correct slot is always the same question: what exact idea does this sentence's wording require to already be sitting in the reader's head, and which single sentence put it there?

This matters for how a whole paragraph gets organized, not just one sentence. A paragraph ordered by time places events in the order they happened, but a paragraph ordered by cause places events in the order the explanation needs, so the same sentence about an event that occurred third in time might need to move earlier if it's actually the trigger for something else. Changing the organizing logic of a paragraph, from chronological to causal, can relocate every sentence in it, including ones that were already correct under the old order.
