Problem: Please answer a question about the following article about Nintendo Entertainment System:
A number of special controllers designed for use with specific games were released for the system, though very few such devices proved particularly popular. Such devices included, but were not limited to, the Zapper (a light gun), the R.O.B., and the Power Pad. The original Famicom featured a deepened DA-15 expansion port on the front of the unit, which was used to connect most auxiliary devices. On the NES, these special controllers were generally connected to one of the two control ports on the front of the console.
What was the name of the auxiliary port used to connect additional devices on the Famicom?
A: DA-15
Problem: Please answer a question about the following article about Universal Studios:
Though Decca would continue to keep picture budgets lean, it was favored by changing circumstances in the film business, as other studios let their contract actors go in the wake of the 1948 U.S. vs. Paramount Pictures, et al. decision. Leading actors were increasingly free to work where and when they chose, and in 1950 MCA agent Lew Wasserman made a deal with Universal for his client James Stewart that would change the rules of the business. Wasserman's deal gave Stewart a share in the profits of three pictures in lieu of a large salary. When one of those films, Winchester '73, proved to be a hit, the arrangement would become the rule for many future productions at Universal, and eventually at other studios as well.
What actor featured in Winchester '73?
A: James Stewart
Problem: Please answer a question about the following article about Red:
The painters of the early Renaissance used two traditional lake pigments, made from mixing dye with either chalk or alum, kermes lake, made from kermes insects, and madder lake, made from the rubia tinctorum plant. With the arrival of cochineal, they had a third, carmine, which made a very fine crimson, though it had a tendency to change color if not used carefully. It was used by almost all the great painters of the 15th and 16th centuries, including Rembrandt, Vermeer, Rubens, Anthony van Dyck, Diego Velázquez and Tintoretto. Later it was used by Thomas Gainsborough, Seurat and J.M.W. Turner.
What was madder lake made from?
A: rubia tinctorum plant
Problem: Please answer a question about the following article about Georgian architecture:
Inside ornament was far more generous, and could sometimes be overwhelming. The chimneypiece continued to be the usual main focus of rooms, and was now given a classical treatment, and increasingly topped by a painting or a mirror. Plasterwork ceilings, carved wood, and bold schemes of wallpaint formed a backdrop to increasingly rich collections of furniture, paintings, porcelain, mirrors, and objets d'art of all kinds. Wood-panelling, very common since about 1500, fell from favour around the mid-century, and wallpaper included very expensive imports from China.
Where was very expensive wallpaper imported from?
A:
China
