Question: Passage: Buy one, get one free -- Economist Alex Tabarrok has argued that the success of this promotion lies in the fact that the price actually takes into account the fact that two items are being sold. The price of ``one'' is somewhat nominal and is typically raised when used as part of a buy one get one free deal. Whilst the cost per item is proportionately cheaper than if bought on its own, it is not actually half price.
Question: is 2 for 1 same as half price

Answer: 0


Question: Passage: Extra innings -- The longest game by innings in Major League Baseball was a 1--1 tie in the National League between the Boston Braves and the Brooklyn Robins in 26 innings, at Braves Field in Boston on May 1, 1920. It had become too dark to see the ball (fields did not have lights yet and the sun was setting), and the game was considered a draw. Played rapidly by modern standards, those 26 innings were completed in 3 hours and 50 minutes. As was the custom, the first pitch was thrown at 3:00 p.m.; home plate umpire Barry McCormick called the game as lights began appearing in the windows of buildings across the Charles River, just before 7:00 p.m.
Question: has a mlb game ever ended in a tie

Answer: 1
