instruction:
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.
question:
Question: Who developed the piece of software that annoyed Trey Parker? Passage:The film opens as South Park creators Trey Parker and Matt Stone leave New York City and the 2011 opening night of their Broadway production The Book of Mormon to return to Los Angeles to begin the fifteenth season of South Park. The documentary chronicles the production of the season premiere, "HumancentiPad", beginning the Thursday prior to airing. Parker and Stone, alongside producers Anne Garefino, Vernon Chatman, Bill Hader, and Susan Arneson, discuss ideas for the episode. Parker mentions his annoyance with downloading the latest version of iTunes, and being forced to comply with the software's long list of terms and conditions. The rant leads to ideas, with Parker instructing the storyboard team on how to stage a shot. The film covers various aspects of production, including voice acting, animation, lip sync, communication with standards and practices, character design, and editing.

question:
Question: Which location in California where the LST-1159 stopped at has a higher land elevation? Passage:Initially attached to Amphibious Forces, Atlantic Fleet, LST-1159 conducted shakedown in Guantánamo Bay and the Caribbean before commencing local operations out of Norfolk and Little Creek, Virginia. She departed Norfolk on 24 February 1954 for duty with Amphibious Forces, Pacific Fleet, and, after a transit of the Panama Canal, reached the west coast on 20 March. The tank landing ship operated out of her new home port, San Diego, until 20 September, including calls at San Francisco, San Pedro, California, and Esquimalt, British Columbia. LST-1159 stopped briefly at Pearl Harbor before proceeding on toward Japan. While on the voyage across the Pacific, the ship was diverted to join Task Force (TF) 98 in Southeast Asian waters and arrived at Henriette Pass, near the port of Haiphong, French Indochina on 29 October. Taking part in "Operation Passage to Freedom", LST-1159 transported refugees from the northern part of what became a divided Vietnam, to the southern ports of Tourane (Da Nang) and Saigon.

question:
Question: On average how large are the whales that were the first known organism to take advantage of the tubercle effect? Passage:The tubercle effect is a phenomenon where tubercles or large 'bumps' on the leading edge of an airfoil can improve its aerodynamics. The effect, while already discovered, was analyzed extensively by Frank E. Fish et al in the early 2000 onwards. The tubercle effect works by channeling flow over the airfoil into more narrow streams, creating higher velocities. Another side effect of these channels is the reduction of flow moving over the wingtip and resulting in less parasitic drag due to wingtip vortices. Using computational modeling, it was determined that the presence of tubercles produces a delay in the angle of attack until stall, thereby increasing maximum lift and decreasing drag. Fish first discovered this effect when looking at the fins of humpback whales. These whales are the only known organisms to take advantage of the tubercle effect. It is believed that this effect allows them to be much more maneuverable in the water, allowing for easier capture of prey. The tubercles on their fins allow them to do aquatic maneuvers to catch their prey.
