SAT Reading Error Log: Find the Missing Evidence

When SAT reading explanations seem obvious only after you see the answer, record the exact evidence that rules each choice in or out. A reading error log should capture the task, your interpretation, the relevant passage detail and the unsupported step. Do not collect answer letters without the reasoning that produced them.

Read an original practice passage

“In a fictional town, a library extended its evening opening hours for one month. Evening visits increased, while morning visits stayed about the same. The library did not measure whether visitors stayed longer or borrowed more books. Staff proposed observing another month before changing the permanent schedule.”

Which conclusion is supported? A: The longer hours caused every visitor to borrow more books. B: Evening visits increased during the trial. C: Morning visitors switched entirely to evening visits. D: The permanent schedule was already changed.

The supported choice is B. It restates an observed change without adding a cause or outcome the passage did not establish. This original short exercise teaches evidence boundaries; it is not a College Board item and is not intended to reproduce the difficulty of a full test.

Explain why the alternatives fail

If you chose A, your error may be adding a plausible story rather than checking the passage. If you chose D, you may have treated a proposal as a completed action. These need different corrections. Write the specific word that changed the claim: caused, every, entirely or already.

Copy the evidence log

Use columns for question task, chosen claim, passage evidence, unsupported step and next check. For the fictional library passage, a row might say: “I treated increased visits as increased borrowing. The passage says borrowing was not measured. Next time I will distinguish the measured outcome from a related outcome.”

College Board's question-bank guide organizes Reading and Writing questions by domain and skill, including command of evidence, inferences and central ideas. Use the official skill labels when they fit. The labels describe the question's demand; your log should additionally describe your own reasoning error.

Make the passage harder in a controlled way

Replace the first observation with “Evening visits increased only on Fridays.” Now revise choice B to “Friday evening visits increased during the trial.” The original broad statement would need qualification. This exercise checks whether you notice scope words instead of relying on the topic's general meaning.

Next, ask which new evidence would be needed to support a claim about borrowing. A suitable answer is borrowing data collected during comparable periods, with attention to other changes that could affect the comparison. The passage alone cannot supply those missing measurements. Do not ask an AI assistant to invent them and then treat the invention as textual evidence.

Review without memorizing

After a break, try a different official question of the same skill and explain your choice before opening the rationale. Revisit the log only after making the new attempt. If the same unsupported step returns, reduce the task to distinguishing “stated,” “reasonable inference” and “not established.”

Use the SAT error-log guide for the wider review process. When several topics compete for attention, follow the practice-test review routine. These exercises support preparation; they do not predict a score or replace official test guidance.
