Fill in the fields and this tool builds a valid question/v1 record — a single-answer practice question, the most common type. Everything runs in your browser; nothing is sent anywhere.
Make every distractor a plausible "right-but-not-best" action, and make sure your correct answer is not the longest or most detailed option — length telegraphs the key.
Files under content/questions/ are JSON arrays, so this record is wrapped in [ … ] — paste it into a new file, or add it as another element of an existing array.
