• Pick the answer that helps more: more correct, more complete, and a better fit for what was asked.
• Read both fully first. The shorter or more confident answer is not always the better one.
• Use "about equal" when they are genuinely close. Don't force a winner.
• Watch for plausible-but-wrong: an answer can sound good and still be inaccurate.
• Say why in a few words, and flag what's weaker (made up, missed the ask, unnatural wording).

How pay works. Each task is judged by at least three workers. Yours pays when your pick matches the group's, with more weight given to workers who have a stronger track record. Picks in the minority are not paid, so expect some tasks not to pay even when you thought about them carefully. Your written reason and hidden test questions are quality checks rather than tiebreakers: work that fails them is not paid even when the pick matches, but they do not override the group's pick. Review usually takes a few hours and can take longer on quieter tasks, because it waits for other workers to reach the same task.
