SAT Overall Structure of a Passage

Some questions ask which choice best describes the overall structure of the text. The choices are short narratives about how the passage moves, and they usually differ in order rather than in content. Building your own outline before reading them makes the comparison mechanical instead of intuitive.

The rule

Write your own one-word outline of the passage first, then find the choice that traces the same elements in the same order.

As you read, label each sentence with one word for its job. Common labels are background, claim, evidence, counterpoint, example, and conclusion. A four-sentence passage might come out as background, claim, evidence, implication. That sequence is your outline, and it takes about as long to build as reading the passage normally does.

Then read each choice as a sequence and compare. A choice saying the text presents a hypothesis and then describes an experiment that supports it matches an outline of claim, then evidence. A choice saying the text describes an experiment and then proposes a hypothesis matches the reverse order. Both mention the same two elements, and only one matches your outline.

SAT passages tend to reuse a handful of shapes. A common belief is stated and then complicated by new evidence. A problem is described and a solution is proposed. A phenomenon is described and two competing explanations are offered. A researcher's method is described and its limitation is noted. Recognizing the shape early tells you what to expect from the rest of the paragraph.

Be strict about elements that are named but absent. If a choice mentions that the text refutes an opposing theory, look for the opposing theory. If a choice says the text offers a solution, find the solution. Passages often raise a problem without solving it, and a choice adding a resolution that never appears is a standard wrong answer.

Finally, check that the choice covers the whole passage. A description that accounts for the first two sentences and ignores the turn in the third is incomplete in the same way a narrow main idea answer is. Structure answers, like central idea answers, have to fit everything.

The trap

Accepting a choice that names the right elements but puts them in the wrong sequence.

Real question

A juvenile octopus can solve a maze it has never seen. It can also open a jar, once. Researchers who test the same animal a week later find that it must work the problem out again from the beginning, and that an animal which first opened a jar in ninety seconds will take nearly as long on its second attempt. Octopuses are widely described as intelligent, and by most measures they are. What they appear to lack is a way of carrying a solution forward in time.

Which choice best describes the function of the sentence "Octopuses are widely described as intelligent, and by most measures they are" in the text as a whole?

Flight recorders survive crashes because they are built to, and engineers list the qualities: a steel shell, thermal insulation, a fixed position in the tail. The list is misleading in one respect. Survival is not a property of the box but of the pairing between the box and the accident, and the tail is safest only in impacts where the aircraft strikes nose first. In water landings and in-flight breakups, the same position is among the worst available. Investigators choose the position that fits the likeliest accident.

Which choice best describes the overall structure of the text?

  • A) It recommends that flight recorders be relocated from the tail of an aircraft to a more survivable position.
  • B) It describes the construction of a flight recorder and then argues that one description of it is imprecise. ✓
  • C) It contrasts flight recorders designed for water landings with those designed for impacts at high speed.
  • D) It lists the features engineers build into a flight recorder so that the device will survive a crash intact.

Why: The text lists the recorder's features, says "The list is misleading in one respect," and shows that the tail's safety depends on the kind of impact. Choice D restates the list the text then qualifies. Choice A suggests a relocation the text never proposes, since no safer position is named. Choice C invents two designs where the text describes one. It contrasts flight recorders designed for water landings with those designed for impacts at high speed. is one design is described; the contrast is between accident types, not designs. It recommends that flight recorders be relocated from the tail of an aircraft to a more survivable position. is no better position is identified, and none is recommended. It lists the features engineers build into a flight recorder so that the device will survive a crash intact. is true of the first sentence, which the rest of the text calls misleading.

Questions students ask

How is this different from a main idea question?

A main idea question asks what the passage claims. A structure question asks how it is arranged. Two passages could share a main idea while being organized differently, so the correct structure answer is about sequence and roles rather than content.

What are the most common passage shapes on the SAT?

A prevailing view followed by evidence that complicates it, a problem followed by a proposed solution, a finding followed by its implications, and a phenomenon followed by competing explanations. Most short passages on the test fit one of these.
