2 corrections applied: Sydney Opera House figures are Australian dollars, not pounds sterling | Kahneman reports the curriculum project was completed in about eight years, not ten
Before(1) The Sydney Opera House, estimated at £7 million, cost £102 million. (2) they increased their estimate to eight years. The project ultimately took ten.
After(1) The Sydney Opera House, estimated at about AU$7 million, cost about AU$102 million. (2) they increased their estimate to eight years. The project ultimately took eight.
Why: Verified both corrections already correctly applied in the article body (AU$ currency for Sydney Opera House; 'took eight' for the curriculum project). No other mentions elsewhere in article. FAQ field checked, does not reference either fact. No changes needed.
