Write a statement that tests one fact at a time. “Evaporation changes liquid water into vapor” is easier to assess than a sentence that also makes claims about wind and temperature. If a sentence contains two independently testable ideas, split it into two questions.
Prefer a direct statement to wording such as “It is not incorrect that evaporation does not require boiling.” Rewrite it as “Evaporation can occur below boiling temperature,” then check it against the source. The question should test understanding, not the ability to decode negatives.
Before using a question, identify the exact passage that establishes its answer. For a false statement, explain which part conflicts with the source. If your notes merely omit the claim, choose a different claim rather than assuming it is false.
Source: “Water freezes at 0°C at standard atmospheric pressure.” Statement: “At standard atmospheric pressure, water freezes at 0°C.” True: the statement preserves the source’s condition.
“Water always freezes at 0°C” removes the pressure condition. Restore that condition so the statement can be checked fairly against the source.
Use one factual claim and keep conditions such as time, pressure or location when they affect the answer.
Test understanding rather than tricks. Avoid double negatives and absolute words that were not in the source.
Identify an exact passage that supports the answer. If the passage does not settle the claim, revise the question.
Select a readable section and choose the true or false question type. Review the generated statements for one clear claim and any necessary conditions. Use a small section first so it is easy to check each question against the material.
After submitting a question in Practice, or finishing the set in Test mode, you can review answers and explanations. Open the associated source reference to check each conclusion. Use the report control if a question is ambiguous or the cited passage does not support it.
