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: How long had Kortrijk been a team when Gillenken made his debut for OH Leuven? Passage:Gillekens made his debut for OH Leuven in the 201415 Belgian Cup in the sixth round match against Kortrijk, a 1-3 loss, although that season he was part of the reserves and only fourth goalkeeper behind Logan Bailly, Yves Lenaerts and Senne Vits. Later that season he also played one match in the 201415 Belgian Second Division against Mons. Although Gillekens was promoted to third keeper for the 201516 season, he did not play a single match that season. Following the relegation from the 201516 Belgian Pro League, first goalkeeper Rudy Riou was released while second goalkeeper Yves Lenaerts had already signed for ASV Geel. As such, Gillekens was promoted to first goalkeeper for the 201617 season in the Belgian First Division B. During the winter 201718 transfer window OH Leuven signed Kawin Thamsatchanan, captain of the Thailand national football team and soon thereafter Gillekens was demoted to reserve goalkeeper. Following Thamsatchanan's injury during the 201819 season, Gillekens again became first goalkeeper for a few matches before then being surpassed by Laurent Henkinet. Towards the end of the season, Gillekens was even demoted to third goalkeeper with Thamsatchanan now taking his place on the bench and after the final match of the season it became clear that Gillekens would not be signing a new deal at OH Leuven.

Question: How old was the Cardinals right fielder when he retired? Passage:The new season brought a Cardinals team that was much changed from the one that went 100-62 in 2005 but fell to the Houston Astros in the NLCS. Starting pitcher Matt Morris, second baseman Mark Grudzielanek, left fielder Reggie Sanders, and relief pitcher Julian Tavarez left the team via free agency. Relief pitcher Ray King was traded to Colorado. Right fielder Larry Walker retired. Brought in to replace the departed Cardinals were right fielder Juan Encarnacion, starting pitcher Sidney Ponson, relief pitchers Braden Looper and Ricardo Rincon, all via free agency, and second baseman Aaron Miles, acquired in the Ray King trade. Left field was left unsettled in the offseason and would remain so all year, with no player getting more than one-third of the playing time at that position.

Question: What was length of the class of USN airship that made the first transatlantic crossing? Passage:In 1944, Argentia served as one of the two stopover bases for the refuelling, maintenance, and crew changes of the six United States Navy (USN) K-class blimps that made the first transatlantic crossings of non-rigid airships. Blimps K-123 and K-130 from USN Blimp Squadron 14 (also known as ZP-14, Blimpron 14, or "The Africa Squadron") left South Weymouth Naval Air Station in Massachusetts on 28 May 1944 and landed at Argentia about 16 hours later. The two K-ships then flew for approximately 22 hours to Lages Field on Terceira Island in the Azores, the second stopover base for the transatlantic flights. The last leg was a ~20-hour flight to the squadron's final destination with Fleet Air Wing (FAW) 15 at Port Lyautey, French Morocco (now Kenitra, Morocco). Blimps K-123 and K-130 were followed by K-109 and K-134 then K-112 and K-101 which left South Weymouth on 11 and 27 June, respectively, in 1944. These six blimps initially conducted nighttime anti-submarine warfare operations to complement the daytime missions flown by FAW-15 aircraft (PBYs and PB4Y-2) using magnetic anomaly detection to locate U-boats in the relatively shallow waters around the Strait of Gibraltar. Later, ZP-14 K-ships conducted minespotting and minesweeping operations in key Mediterranean ports and various escort missions including that of the convoy carrying Franklin Roosevelt and Winston Churchill to the Yalta Conference in early 1945. In late April 1945, K-89 and K-114 left NAS Weeksville (now Coast Guard Air Station Elizabeth City) in North Carolina and flew a southern route to NAS Bermuda, the Azores, and Port Lyautey, where they arrived on 1 May 1945.
