How we make sure every answer is right.
Verbal reasoning practice has a trust problem. Answers get disputed, explanations don’t explain, and “Cannot Say” often feels arbitrary. We built this site around a single rule: no question is published unless its answer can survive an attack. This page explains exactly what that means.
The five steps
- Constructed, not just written.Every question starts as a structured specification — the propositions a passage asserts, the logical rule a deduction follows, or the tagged relationship between words. The correct answer is derived from that structure. It is never somebody’s opinion recorded in a spreadsheet.
- Solved blind. An independent solver — with no access to the intended answer or its reasoning — answers the question cold and must cite the evidence for its verdict. If it disagrees with the constructed answer, the question fails.
- Attacked. A separate adversarial check tries to defend every wrong answer as if it were right. If any alternative answer can be reasonably defended, the question fails. This is how we catch ambiguity before you do.
- Withheld when contested.Questions that fail don’t get “fixed up” and pushed through. They’re withheld. Every question on this site passed all checks — currently 654 of them, with every verification recorded.
- Disputed openly.Every question carries a dispute button. If you believe an answer is wrong, tell us — a person reviews it, and a question under dispute is pulled from circulation until resolved. We’d rather correct one question than defend it.
Evidence, always
Every answer on this site cites its evidence: the highlighted passage span, the logical step, or the word relationship that decides it. If we can’t show you why an answer is right, we don’t ask you to accept it.
What we don’t do
We don’t invent percentiles or improvement statistics. We don’t claim affiliation with any test provider. We don’t publish questions to hit a volume number. Where we’re uncertain, we withhold — that’s the whole method.
