TASK DEFINITION: In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.
PROBLEM: Question: What year did construction begin on the dam that the river passes through before Afterbay Dam? Passage:The Bighorn River begins as the Wind River in the Rocky Mountains at Wind River Lake, near Two Ocean Mountain and the summit of Togwotee Pass. The Wind River flows southeast receiving the east fork of the Wind River from the north, and enters the Wind River Basin, flowing past Dubois and Johnstown, to Riverton, where it receives the Little Wind River. The river then changes direction to the northeast and then the north, flowing into Boysen Reservoir, which is formed by Boysen Dam. Below the dam it enters the Wind River Canyon, where the river narrows and forms many rapids. At the end of the canyon the Wind River widens out in an area called the Wedding of the Waters where it becomes the Bighorn River and enters the Bighorn Basin. The Bighorn continues northward, passing through Thermopolis, Worland, and Basin. At Greybull it receives the Greybull River, and about north of that confluence it enters Bighorn Lake, where it is joined by the Shoshone River. North of the confluence with the Shoshone, the reservoir narrows as the river enters the Bighorn Canyon, where it crosses into Montana. At the end of the canyon, the river passes through Yellowtail Dam and Afterbay Dam. The river turns to the northeast and enters the Great Plains. At Hardin the river is joined by the Little Bighorn River. Approximately downriver from the Little Bighorn, in Big Horn County, the Bighorn empties into the Yellowstone.

PROBLEM: Question: Who is the oldest member of Jan Kuehnemund's band? Passage:Born in St. Paul, Minnesota, Kuehnemund formed an all-female band known as Genesis in St. Paul in 1971, initially as a quintet under the name Lemon Pepper. Her father Carl served as a roadie during her band's earliest days. Genesis was later renamed Vixen to prevent confusion with the same-named English band before breaking up in 1974. A bandmate of hers during that year was Nancy Shanks. After a six-year hiatus she reformed Vixen and shortly moved her band to Los Angeles in 1981, and, in 1983, singer Janet Gardner joined her. The band gained notice by appearing in the 1984 teen film Hardbodies under the on-screen name Diaper Rash. They were also a quintet at the time. She eventually added Roxy Petrucci on drums and fellow Minnesotan Share Ross, then known as Share Pedersen, on bass, the lineup that signed to EMI Records. They released their self-titled debut, Vixen, in 1988. It was released by Manhattan Records in the U.S. and Canada. The band toured with the Scorpions, Ozzy Osbourne, and Bon Jovi, and appeared in Penelope Spheeris' 1988 film, , although only Gardner, Pedersen, and Petrucci appeared in the film.

PROBLEM: Question: Who was the head of Heinkel when the Heinkel He 176 first flew? 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 Peenemunde 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, 400kg (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).
