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.

Input: Consider Input: Question: Which movie did Indrajith Sukumaran act in immediately preceding his role in Amen? Passage:It took another two years before he came up with his third movie, Amen, in 2013, which had Indrajith Sukumaran, Fahad Fasil, Swathi Reddy and Kalabhavan Mani in the lead roles and the movie succeeded at the box office while drawing good critical response. After a gap of almost two years, Pellissery released his fourth film, Double Barrel, a comic thriller, with Prithviraj Sukumaran, Indrajith Sukumaran, Arya, Sunny Wayne and Asif Ali in the lead roles. However, the film did not succeed critically or commercially. The next project, Angamaly Diaries, a black comedy cloaked in a gangster plot that revolves around the locale of Angamaly, was scripted by popular actor, Chemban Vinod Jose. The film, made on a small budget of million, was received well at the box office and drew critical acclaim; Anurag Kashyap opined that Angamaly Diaries was his film of the year. Ee.Ma.Yau, his next film based on a satire written by P. F. Mathews and with his regular composer, Prashant Pillai, scoring the music, was premiered on November 30, 2017 but the release was delayed due to undisclosed reasons. Before it was released on May 4, 2018, the film received the Kerala State Film Award for Best Director at the 48th Kerala State Film Awards. The film also won him the Silver Peacock Award for the best director at the 49th International Film Festival of India (IFFI), 2018, which was held in Goa in November 2018 (Chemban Vinod Jose, the protagonist of the film, also received the Silver Peacock Award for the best actor.) followed by the Sinema Zetu International Film Festival Award for Best Direction.

Input: Consider Input: Question: Who was the lead character in the original film that Rossum appeared in the remake of in 2006? Passage:In 2006, Rossum appeared in Poseidon, Wolfgang Petersen's remake of the disaster film The Poseidon Adventure. She played Jennifer Ramsey, the daughter of Kurt Russell's character. Rossum described the character as being proactive and strong in all situations, rather than a damsel in distress. Rossum also appeared as Juliet Capulet in a 2006 Williamstown Theatre Festival production of William Shakespeare's Romeo and Juliet. In early 2009, Rossum appeared in Dragonball Evolution. Her next big screen venture was the indie Dare which was an official selection of the 2009 Sundance Film Festival. In November 2009, Rossum appeared in Broadway's 24 Hour Plays in which actors, writers, and directors collaborate to produce, and perform six one-act plays within 24 hours to benefit the Urban Arts Partnership. Rossum appeared in Warren Leight's "Daily Bread", directed by Lucie Tiberghien.

Input: Consider Input: Question: How old was von Braun when his team installed Walter rockerts into experimental aircrafts? Passage:At the same time that Walter was developing submarine engines, he was also applying his ideas to rocketry. The high-pressure gas mixture created by the rapid decomposition of hydrogen peroxide could not only be used in a turbine, but if simply directed out of a nozzle, created considerable thrust. Wernher von Braun's rocketry team working at Peenemünde expressed interest in Walter's ideas, and in 1936 began a programme of installing Walter rockets into aircraft. The experimental results obtained by von Braun created interest among Germany's aircraft manufacturers, including Heinkel and Messerschmitt, and in 1939, the Heinkel He 176 became the first aircraft to fly on liquid-fuelled rocket power alone. This type of engine went on to become the cornerstone of the Messerschmitt Me 163 rocket-powered fighter, when married to Alexander Lippisch's revolutionary airframe design. Throughout the course of World War II, Walter's aircraft engines became increasingly powerful and refined. The original design of simply decomposing hydrogen peroxide was soon changed to its use as an oxidizer (much like dinitrogen tetroxide would be used later) when combined with a hydrazine/methanol true rocket fuel designated C-Stoff, into the hot, high-pressure gases, and in later, never-deployed developments, a second, 400 kg (880 lb) thrust "cruising" combustion chamber, nicknamed a Marschofen, was added below the main chamber to allow for more precise control of the engine. Versions of this engine were intended to power a variety of aircraft design proposals and missile projects and was also licence-built in Japan (see HWK 109-509).
