[Q]: Question: How many battles had Oswald Watt commanded by the year Holden joined the Australian Imperial Force? Passage:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No.2 Squadron. Commanded by Major Oswald Watt, No.2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

[Q]: Question: Who founded the race team that Fisher switched to in 2004? Passage:On February 12, 2004, it was announced that Fisher had switched from Dreyer & Reinbold Racing to Kelley Racing; the team expressed its hope of taking part for the majority of the 2004 season but Fisher did not contest the season-opening Toyota Indy 300 due to a lack of sponsorship. Two months later, Fisher entered the Indianapolis 500 in Kelley's No. 39 Dallara Toyota Indy V8 entry after they received sponsorship for the event. She qualified in 19th and finished the rain-shortened race in 21st. Afterward she sought another team for which to drive. Later that year, Fisher made her stock car racing debut, entering a NASCAR West Series (now NASCAR K&N Pro Series West) race in the No. 20 Bill McAnally Racing car at Phoenix after Richard Childress Racing (RCR) owner Richard Childress asked Bill McAnally if she could fill in for Kerry Earnhardt, who was competing in the EA Sports 500 at Talladega Superspeedway. Fisher qualified in 14th and finished in 21st place due to a battery failure after 104 laps.

[Q]: Question: Which of the provinces where French is an official language has the highest population? Passage:In 2011, the total number of native French speakers in Canada was around 7.3 million (22% of the entire population), while another 2 million spoke it as a second language.

At the provincial level, French is the sole official language of Quebec as well as one of two official languages of New Brunswick, and jointly official (derived from its federal legal status) in Nunavut, Yukon, and the Northwest Territories. Government services are offered in French at select localities in Manitoba and Ontario (through the French Language Services Act) and, to a lesser extent, elsewhere in the country, depending largely on the proximity to Quebec and/or French Canadian influence on any given region.
