Passage:The off-season brought a few changes to the coaching staff, as Notre Dame lost three assistant coaches to other opportunities: Kerry Cooks left the coaching staff to take the same position at the University of Oklahoma. Matt LaFleur departed to take the same position for the Atlanta Falcons of the NFL, and Tony Alford left the university to take the same position at Ohio State University. Also, Outside Linebackers coach Bob Elliott moved into an off-the-field coaching role within the program. To replace their losses, Notre Dame welcomed the addition of four new assistant coaches.

Input: Consider Input: Question: Who was the founder of the railroad? Passage:The original train track through Irwindale were built by the Los Angeles and San Gabriel Valley Railroad. The Gold line uses the old right of way of the Los Angeles and San Gabriel Valley Railroad who built the first train tracks through Irwindale in 1887. The Los Angeles and San Gabriel Valley Railroad was founded in 1883, by James F. Crank with the goal of bringing a rail line to San Gabriel Valley from downtown Los Angeles. Los Angeles and San Gabriel Valley Railroad was sold on May 20, 1887 into the California Central Railway. In 1889 the rail line was consolidated into Southern California Railway Company. On Jan. 17, 1906 Southern California Railway was sold to the Atchison, Topeka and Santa Fe Railway and called the Pasadena Subdivision. Amtrak-Santa Fe ran the Southwest Chief and Desert Wind over this line through Irwindale, but relocated the Desert Wind to the Fullerton Line in 1986. The Santa Fe line served the San Gabriel Valley until 1994, when the 1994 Northridge earthquake weakened the bridge in Arcadia and the track was closed till the Gold line was built. The rail line crosses the San Gabriel River on a long girder bridge, then passes through the Santa Fe Dam Recreation Area (how it received its name). The rail line intersected the north end of the former SP Azusa Industrial Track at Irwindale (MP 118.2). Irwindale had a 6,165 foot rail siding that passed the Miller Brewing Company's Irwindale brewery. From there the tracks continued and crossed beneath Irwindale Avenue.

Input: Consider Input: Question: How long had Budweiser been in business when they first featured the Budweiser Clydesdales in a Super Bowl commercial? Passage:The beer brand Budweiser has long been a Super Bowl fixture. Its parent company Anheuser-Busch held a long-term contract with the NFL that allowed it to buy several slots of air time from the game's broadcaster each year at a steep discount, a contract that ran through Super Bowl 50; the company continues to buy multiple commercials in each game. Budweiser runs several advertising campaigns throughout each game, one of which has traditionally featured its mascots, the Budweiser Clydesdales. The Clydesdales were included in at least one Super Bowl commercial every year from Super Bowl IX in 1975 through Super Bowl LI in 2017. Budweiser's parent company Anheuser-Busch has been the most successful advertiser in the annual Super Bowl Ad Meter survey organized by USA Today, having finished first on the survey fourteen times. When USA Today held an "All-Time Ad Meter" bracket tournament in 2014, two Budweiser commercials met in the finals; the winner was a 2008 ad spoofing Rocky, which went against its 1999 ad "Separated at Birth", which featured a pair of Dalmatian puppies given to two separate owners, but eventually seeing each other again after one became a mascot dog on the Clydesdales' carriage.
