Question: How many races had Sellers run the year he replaced Josh Reaume? Passage:Obaika Racing entered competition in 2015. The team signed driver Josh Reaume, who met team owner Victor Obaika while on humanitarian missions in Africa as a child. The 97 team debuted at the Daytona International Speedway in the Xfinity Series season-opening Alert Today Florida 300, with Reaume finishing 23rd. After three races, with one DNQ, Peyton Sellers replaced Reaume. In April 2015, the team secured their first sponsor vacation provider VroomBrands, which is owned by Obaika. VroomBrands wrapped the No. 97 in designs such as a Zebra representing their African safari package (debuted at Richmond International Raceway) and the Cheetah print representing their tours in Asia (debuted at Talladega Superspeedway). At the Winn-Dixie 300 at Talladega, Sellers scored the team's first top-20 finish, finishing 18th despite being involved in a ten-car wreck that sent cars spinning down pit road. Johanna Long replaced Sellers for the U.S. Cellular 250 at Iowa Speedway. After one more start for Sellers at Watkins Glen, the team introduced various drivers for the rest of the season. Dylan Kwasniewski debuted with the team in the Nationwide Children's Hospital at Mid-Ohio Sports Car Course, finishing 34th due to mechanical problems after running in the top 10. Kwasniewski would run the next two races for the team. Parker Kligerman drove the car in the VFW Sport Clips Help a Hero 200 at Darlington Raceway, Mason Mingus in the Furious 7 300 at Chicagoland Speedway, and Ryan Ellis in the Hisense 200 at the Dover International Speedway.

Question: In what era did the architectural style of Ince Blundell Hall emerge?  Passage:Ince Blundell Hall is in Georgian style. It is constructed in brick with sandstone dressings, and has an L-shaped plan. The main block faces southeast; it is in two storeys with an attic, and has a front of nine bays. Richard Pollard and Nikolaus Pevsner describe the front as being in late English Baroque style, and consider that it was "evidently inspired" by the front of Buckingham Palace, London. Between the upper storey and the attic is an entablature with a cornice and a panelled parapet. The central three bays project forward, the lower storeys are flanked by pairs of giant pilasters, and at the sides of the central doorway are giant columns. There are more pilasters at the ends of the building, and in the central three bays of the attic. All the pilasters and columns are Corinthian in style. The windows are sashes and are surrounded by architraves. The ground floor windows in the central bays have segmental heads with keystones, and those in the outer bays have friezes and pediments carried on consoles. Below the upper floor windows are panelled aprons and consoles. The central doorway has a segmental head and a keystone carved with the Blundell arms. At the corners of the front are quoins.

Question: What is the population of the city where Lack was born? Passage:Fredell Lack was born in Tulsa, Oklahoma, the oldest of three children of Jewish Eastern European (Latvian) immigrants, Abram I. Lack and Sarah Stillman Lack (who was a sister of noted painter Ary Stillman). She began violin lessons at age six, studying with Tosca Berger. When Fredell was 10, she moved with her family to Houston, Texas. There she studied with Josephine Boudreaux, the concertmaster of the Houston Symphony. At age 11, she first soloed with orchestra, performing the Wieniawski Concerto No. 2 with the Tulsa Philharmonic. At 12, Lack was accepted into the New York City studio of the legendary violinist and pedagogue Louis Persinger, whose other students included such artists as Yehudi Menuhin, Isaac Stern, and Ruggiero Ricci. She moved to New York and completed her pre-college schooling at the Bentley School while continuing her violin lessons with Persinger. At 17, she made her professional solo debut, playing the Mendelssohn Violin Concerto with the St. Louis Symphony. Subsequently she received a full scholarship to the Juilliard School in New York. She continued studying violin with Persinger there and also was deeply influenced by her study of chamber music with Felix Salmond. She received the Diploma from Juilliard at age 21.
