Conclusions That Reinforce the Essay's Main Claim

An argument builds toward its last sentence. If that sentence hands the reader a brand-new fact, the essay has spent its final moment on something it never defended, and the claim is left hanging with no push behind it. The reader's last impression is a stray detail, not the point the whole essay was built to prove. A good closer does the opposite: it lands on the claim, restated so it feels earned rather than repeated.

The trick is restating without repeating. Pull the strongest piece of evidence from the body paragraphs and fuse it with the claim in one compact image or trade-off, so the sentence sounds new even though the idea is the same one argued all along. A line like 'An hour that costs the district a bus contract buys its students a year of better mornings' takes the cost (buses) and the benefit (sleep, grades) raised in the body paragraphs and presses them together into a single payoff line. That is restating in stronger terms.

This sits right next to the question type asking what a weak ending does wrong, and the two are really one skill. Whether the test asks you to pick the best closer or to diagnose a bad one, you are checking the same thing: does this sentence serve the claim, or does it drift off into new territory, a mere list of paragraphs, or an action nobody can still take. Whole-essay questions often test exactly this fit between an ending and the argument it's supposed to close.
