The problem: Answer a question about this article:
Two major hardware revisions of the Xbox 360 have succeeded the original models; the Xbox 360 S (also referred to as the "Slim") replaced the original "Elite" and "Arcade" models in 2010. The S model carries a smaller, streamlined appearance with an angular case, and utilizes a redesigned motherboard designed to alleviate the hardware and overheating issues experienced by prior models. It also includes a proprietary port for use with the Kinect sensor. The Xbox 360 E, a further streamlined variation of the 360 S with a two-tone rectangular case inspired by Xbox One, was released in 2013. In addition to its revised aesthetics, Xbox 360 E also has one fewer USB port and no longer supports S/PDIF.
What video input format is not supported by the 360 E?
****
The answer: S/PDIF


Problem: Please answer a question about the following article about Solar energy:
Solar energy may be used in a water stabilisation pond to treat waste water without chemicals or electricity. A further environmental advantage is that algae grow in such ponds and consume carbon dioxide in photosynthesis, although algae may produce toxic chemicals that make the water unusable.
What is a reason why the water from a water stabilisation pond may be unusable?
A: algae may produce toxic chemicals

Problem: Other public festivals were not required by the calendar, but occasioned by events. The triumph of a Roman general was celebrated as the fulfillment of religious vows, though these tended to be overshadowed by the political and social significance of the event. During the late Republic, the political elite competed to outdo each other in public display, and the ludi attendant on a triumph were expanded to include gladiator contests. Under the Principate, all such spectacular displays came under Imperial control: the most lavish were subsidised by emperors, and lesser events were provided by magistrates as a sacred duty and privilege of office. Additional festivals and games celebrated Imperial accessions and anniversaries. Others, such as the traditional Republican Secular Games to mark a new era (saeculum), became imperially funded to maintain traditional values and a common Roman identity. That the spectacles retained something of their sacral aura even in late antiquity is indicated by the admonitions of the Church Fathers that Christians should not take part.
Who paid for the most lavish of festival events?
The answer is the following: emperors


Input: Article: There is no single standard for HDTV color support. Colors are typically broadcast using a (10-bits per channel) YUV color space but, depending on the underlying image generating technologies of the receiver, are then subsequently converted to a RGB color space using standardized algorithms. When transmitted directly through the Internet, the colors are typically pre-converted to 8-bit RGB channels for additional storage savings with the assumption that it will only be viewed only on a (sRGB) computer screen. As an added benefit to the original broadcasters, the losses of the pre-conversion essentially make these files unsuitable for professional TV re-broadcasting.

Now answer this question: Before being converted to RGB, colors are ususally broadcasted using what color space?

Output:
YUV
