TASK DEFINITION: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
PROBLEM: passage: The Boeing 747 Dreamlifter, also known as the Boeing 747-400 Large Cargo Freighter (LCF), is a wide-body cargo aircraft. At 65,000 cubic feet (1,840 cubic meters) the cargo hold is the largest in the world for an aircraft. It can hold three times the volume of a 747-400F freighter. Cargo is placed in the aircraft by the world's longest cargo loader. It is an extensively modified Boeing 747-400 that is used exclusively for transporting Boeing 787 Dreamliner aircraft components to Boeing's assembly plants from suppliers around the world.
 question: the largest cargo air freighter in the world is made by boeing?

SOLUTION: Yes

PROBLEM: passage: Green is used as a backdrop for TV and electronic cinematography more than any other colour because television weathermen tended to wear blue suits. When chroma keying first came into use in television production, the blue screen that was then the norm in the movie industry was used out of habit, until other practical considerations caused the television industry to move from blue to green screens. Broadcast quality color television cameras use separate red, green and blue image sensors, and early analog TV chroma keyers required RGB component video to work reliably. From a technological perspective it was equally possible to use the blue or green channel, but because blue clothing was an ongoing challenge, the green screen came into common use. Newscasters sometimes forget the chroma key dress code, and when the key is applied to clothing of the same color as the background, the person would seem to disappear into the key. Because green clothing is less common than blue, it soon became apparent that it was easier to use a green matte screen than it was to constantly police the clothing choices of on-air talent. Also, because the human eye is more sensitive to green wavelengths, which lie in the middle of the visible light spectrum, the green analog video channel typically carried more signal strength, giving a better signal to noise ratio compared to the other component video channels, so green screen keys could produce the cleanest key. In the digital television and cinema age, much of the tweaking that was required to make a good quality key has been automated. However, the one constant that remains is some level of color coordination to keep foreground subjects from being keyed out.
 question: can you wear blue on a green screen?

SOLUTION: Yes

PROBLEM: passage: The episode is set four months after Dean goes to hell in No Rest for the Wicked at the end of season 3. The narrative follows the brothers Dean (Jensen Ackles) and Sam Winchester (Jared Padalecki) as Dean returns from hell and tries to discover how he came back to life. The episode is perhaps most significant for introducing the angel Castiel (Misha Collins), who would become the longest surviving regular character.
 question: does dean come back to life in supernatural?

SOLUTION:
Yes
