SAT — rhetorical synthesis

Rhetorical synthesis is the question type that punishes careful reading most reliably, because reading carefully is not what it asks for. A student's research notes are given, then a goal — emphasize a difference, introduce the subject, present a finding with its evidence — and four sentences the student might write. All four are true to the notes. Every one of them. The only thing separating the right answer from the others is whether it does the job the goal named, and a candidate who checks the sentences against the notes instead of against the goal will find four correct answers and no way to choose.

That is how these ten are built, and it is a deliberate constraint rather than an accident: a wrong option that misstates the notes would turn the question into a comprehension exercise and remove everything this type exists to test. The four ways a true sentence can fail recur across the bank. It can report facts accurately and never touch the goal at all — naming a manufacturer when the goal was to explain a consequence. It can address the goal and omit the one fact the goal turns on. It can compare the wrong pair. Or it can draw a conclusion the notes fully support and that nobody asked for, as when a sentence explains why a high trail closes in winter in answer to a question about differences.

Two structural habits are worth taking from the explanations. The first is that a comparison needs two subjects in one sentence: a sentence about a single plant cannot establish a similarity, however true it is and however many shared facts it happens to mention. The second is that emphasis is carried by construction as much as by content — "while", "whereas", "though one is X and the other Y" do work that "and" does not, and two facts joined by "and" report a difference without emphasizing it.

The ten goals are spread across five kinds, each used twice, and the subjects range over settlements, drones, symphonies, ice cores, bridges, pigments, software, trails, solar panels and plants. Every person, study, institution, firm, place and work in the notes is invented, and no invented finding is attributed to a real organization. Nothing is reproduced from any College Board publication, released test, practice test, question bank or scoring guideline.

• Read the stated goal before the options, and judge each sentence against it rather than against the notes
• Recognize that every option may be accurate and that accuracy therefore decides nothing
• Reject a sentence that reports facts without addressing the goal at all
• Reject a sentence that meets the goal but omits the fact the goal turns on
• Spot a conclusion the notes support that the goal did not ask for
• Require two subjects in one sentence before accepting a comparison of any kind
• Use construction, not just content, to tell emphasis from mere reporting
• Say what an audience unfamiliar with a subject needs to be told first
• Frame a finding together with the specific evidence that supports it

While researching a topic, a student has taken these notes. "The Alpine-Peak trail climbs to an elevation of three thousand meters. It is open from June to September. The Coastal-Path trail climbs to an elevation of two hundred meters. It is open all year round. Both trails run about twelve miles and both are maintained by the National Parks Service." The student wants to emphasize a difference between the two trails.
