In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: What album was the song "Ignorance" released from? Passage:The Honda Civic tour was the biggest production the band had had so far. The stage was constructed of 3 ramps up to a platform behind the drum set, and 6 large video screens behind that. The show began with a large black curtain concealing the stage while the band played an instrumental intro, with spotlights revealing the silhouettes of the band. As the intro ended, they begin playing "Ignorance" as the curtain simultaneously dropped, the video screens flashing the band's logo during the intro, as the intro progressed the video screen changed to images of light bulbs (similar to the song's music video) during the intro, light bulbs also swung down from the top of the stage, continuing to swing throughout the song. The band then played "Feeling Sorry" as the video screens each showed a live feed of each member of the band performing during the choruses, at the end of the bridge the band would stop playing and Hayley would greet the crowd and welcome them to the tour. After playing "That's What You Get" and "Emergency" the band played "Playing God" as the video screens showed images of picture frames, the same picture frames on the back of Brand New Eyes and the song's single cover. After that they played Careful, as images of the Brand New Eyes butterfly flashed during the chorus, they then continued with their hit-single "Decode" as the video screen showed the band running through the forest with fireworks and flares, the video has been described as a part-two to the songs music video. After that Hayley Williams and Josh Farro moved to stage left and performed an acoustic cover of Loretta Lynn's "You Ain't Women Enough." After that, a red couch (similar to the one on the cover of All We Know is Falling) and a small lamp were brought out and the band performed a three song acoustic set, during this the light bulbs from Ignorance were brought down again to illuminate the stage. After that the band returned with "Let the Flames Begin" while the video screens showed images of open hands during the 'Oh Father' outro. They then performed "Crushcrushcrush" and "Pressure " stopping in the bridge during "Pressure" for Hayley to introduce all the band members, and for Josh to introduce Hayley. They then performed "Looking Up" while each of the video screens showed lyrics to the song and each of the band members daily lives, at the end of the song all the members came together to ride bikes as the split-screens faded away. They then ended their main set with their biggest hit "The Only Exception" as pyrotechnics were used during the last chorus of the song. The band then exited and come back for an encore, starting with "Brick By Boring Brick" while the video screens showed various images, including deserts, snakes, the Brand New Eyes butterfly, and hot air balloons. After "Brick" the band concluded their set with their breakthrough song "Misery Business" as flashing images of the "Riot!" logo filled the video screens, during the bridge Williams would let one, or sometimes various fans on stage to sing the rest of the song or sometimes play guitar, and as the last chorus came in confetti cannons were shot towards the crowd. The set concluded with the video screen showing Paramore's logo and the band bowing then leaving the stage. They used the same production for their Oceania and UK tours.

Question: Who was older the year Culberson signed with the Dodgers, Dave Roberts or Boone Logan? Passage:Culberson was signed by the Dodgers in November 2015 and invited to spring training, where he impressed new Dodgers manager Dave Roberts. After an injury to Howie Kendrick opened a spot for him, Culberson made the Dodgers 2016 Opening Day roster. He was designated for assignment in July and optioned to the Oklahoma City Dodgers, then recalled a month later. Culberson ended the big club's final home game of the season with a walk-off home run against former Rockies teammate Boone Logan, clinching the Dodgers' fourth consecutive National League West division title. He played in 34 games for Los Angeles, hitting .284 and in 70 games for Oklahoma City, hitting .260. He had no hits in seven at-bats with two strikeouts in the 2016 National League Division Series. He was outrighted to the minors and removed from the 40-man roster on December 9, 2016. He was assigned to Oklahoma City to begin the season. He remained in the minors for the conclusion of the AAA season, hitting .250 in 108 games and returned to the majors with the Dodgers on September 4. In 15 games for the Dodgers, he hit .154 with two hits in 13 at-bats. When starting shortstop Corey Seager was left off of the 2017 NLCS roster because of a back injury, Culberson was added to the post-season roster. He appeared in all five games of the series, with five hits in 11 at-bats for a .455 average. In the 2017 World Series, Culberson had three hits in five at-bats, including his first career post-season home run, which he hit off Chris Devenski of the Houston Astros in the 11th inning of Game Two.

Question: When was the type of geometry Hirschfeld published about in 1979 first invented? Passage:In 1979 Hirschfeld published the first of a trilogy on Galois geometry, pegged at a level depending only on "the group theory and linear algebra taught in a first degree course, as well as a little projective geometry, and a very little algebraic geometry." When q is a prime power then there is a finite field GF(q) with q elements called a Galois field. A vector space over GF(q) of n + 1 dimensions produces an n-dimensional Galois geometry PG(n,q) with its subspaces: one-dimensional subspaces are the points of the Galois geometry and two-dimensional subspaces are the lines. Non-singular linear transformations of the vector space provide motions of PG(n,q). The first book (1979) covered PG(1,q) and PG(2,q). The second book addressed PG(3,q) and the third PG(n,q). Chapters are numbered sequentially through the trilogy: 14 in the first book, 15 to 21 in the second, and 22 to 27 in the third. Finite geometry has contributed to coding theory, such as the Goppa code, so the field is supported by computer science. In the preface of the 1991 text Hirschfeld summarizes the status of Galois geometry, mentioning maximum distance separable code, mathematics journals publishing finite geometry, and conferences on combinatorics featuring Galois geometry. Colleague Joseph A. Thas is coauthor of General Galois Geometries on PG(n,q) where n ≥ 4.
