0:17Example 1
For decades, restoration crews treated fallen timber in a river as debris to be cleared, on the reasoning that open channels move water fastest. A survey of forty restored reaches complicates that reasoning: the stretches that kept their fallen wood held more juvenile fish and lost less streambed to erosion than the cleared stretches. Clearing is not therefore obsolete. Where a channel runs under a bridge or through a town, the wood still has to come out. What the survey changes is the default: crews now argue for removal instead of assuming it. Which choice best describes the overall structure of the text? A) It presents a long-standing practice, introduces evidence that complicates it, and describes a narrowed role for the practice. B) It describes a survey of forty river reaches and lists what the survey found. C) It argues that clearing fallen timber from rivers should stop. D) It contrasts two groups of researchers who disagree about restoration.
- Read for moves, not details. One pass, three marks, one verb each. Sentence one: crews assumed fallen wood should come out. Verb: assumed.
- Sentence two: the survey shows more young fish and less erosion where the wood stayed. That is the turn. Verb: complicated.
- The final sentences pull back: clearing is not obsolete, it just stops being automatic. The practice keeps a smaller role. Verb: narrowed. Shape: old view, new evidence, narrowed revision.
- Read the choices as shapes. A names all three moves: a long-standing practice, evidence that complicates it, a narrowed role. It covers the whole text.
- B describes the survey accurately and stops: one block out of three. C says clearing should stop, but the text says not obsolete, so C is more certain than the text. D invents two camps of researchers arguing; nobody argues here, the text revises its own default.
Answer: A
A is the only description that covers every move the passage makes, and a structure answer has to describe all of the text, not part of it. The trap is B: it is a true statement about the middle third, and students who read for content rather than shape reward it for being accurate. C is the second trap, a stronger claim than a text that hedges with not therefore obsolete ever makes.
2:19Example 2
Museums once labeled the small clay figures as toys, largely because they were found in domestic rooms. Recent excavation notes record the same figures in storerooms beside grain jars and account tablets. The figures may still have been toys. But the notes make a single-purpose label harder to defend than it was. Which choice best describes the overall structure of the text? A) It states a traditional interpretation, presents evidence that unsettles it, and withholds a firm replacement. B) It explains where the clay figures were found and what was stored beside them. C) It proves that the clay figures were used in accounting. D) It compares two excavation methods.
- Map the moves. Sentence one: museums labeled the figures toys because of where they were found. Verb: labeled, a traditional reading.
- Sentence two: excavation notes put the same figures in storerooms beside grain jars and account tablets. Verb: unsettled.
- Sentences three and four: they may still have been toys, but a single-purpose label is harder to defend. No new label is offered. Verb: withheld. Shape: old label, evidence that unsettles it, no firm replacement.
- Match the shape. A names all three: traditional interpretation, unsettling evidence, withheld replacement. B is only where the figures were found, one block out of three. C says the text proves an accounting use, but the text says may still have been toys, so C is more certain than the text ever gets. D compares excavation methods, which the text never mentions.
Answer: A
A follows the passage's three moves in order and stops exactly where the passage stops, without a firm conclusion. B is the trap for detail readers: every word of it is true, and it covers a third of the text. C is the trap for students who finish the argument the author deliberately left open; the storeroom evidence suggests accounting, but the text only says the toy label is harder to defend.

Lesson transcript
The narration of the video, word for word, under its chapter headings.
0:17The setup
Structure questions ask what the whole text does, not what it says. Read the moves, not the details. Here is a passage and four descriptions of its shape.
0:49Three moves, one pass
One pass, three marks. Sentence one: crews assumed fallen wood should come out. That is the old default. Then the survey complicates it. More young fish, less erosion where the wood stayed. That is the turn. Then the text pulls back. Clearing is not obsolete, it just stops being automatic. Old view, new evidence, narrowed revision. Now read the choices as shapes. A names all three moves. Nothing else does. Now the wrong answers. B describes the survey, accurately, and stops there. That is one block out of three. C says clearing should stop, but the text says the opposite. Not obsolete. And D invents two camps of researchers arguing. Nobody argues here. The text simply changed its own default.
1:45The three shapes
The S.A.T. reuses three shapes. Claim, counter, resolution. Problem, attempt, limit. Old view, new evidence, revision. Learn the three and most structure questions become recognition instead of reading.
2:19Your turn
Your turn. Map the moves, then pick the shape. Ten seconds. A. Old label, evidence that unsettles it, and no firm replacement. B is only where things were found, one block out of three. C is more certain than the text ever gets.
2:53Three ways this goes wrong
Three ways this goes wrong. Picking a true detail instead of the shape. Picking a stronger claim than the text makes. And inventing people who disagree, when the text is just changing its mind.
3:27Name each move in one verb
Name each move in one verb. Then match the shape.
