Problem: High-definition television:

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.

When transmitted over the internet,  black and white are typically to what?

A: unanswerable


Problem: Each play constitutes a down. The offence must advance the ball at least ten yards towards the opponents' goal line within three downs or forfeit the ball to their opponents. Once ten yards have been gained the offence gains a new set of three downs (rather than the four downs given in American football). Downs do not accumulate. If the offensive team completes 10 yards on their first play, they lose the other two downs and are granted another set of three. If a team fails to gain ten yards in two downs they usually punt the ball on third down or try to kick a field goal (see below), depending on their position on the field. The team may, however use its third down in an attempt to advance the ball and gain a cumulative 10 yards.
How many plays can the offence run without gaining ten yards?

Answer: three

Question: In the early 20th century, the vast conscription of Italian men from all throughout Italy during World War I is credited with facilitating the diffusion of standard Italian among less educated Italian men, as these men from various regions with various regional languages were forced to communicate with each other in a common tongue while serving in the Italian military. With the eventual spread of the radio and television throughout Italy and the establishment of public education, Italians from all regions were increasingly exposed to standard Italian, while literacy rates among all social classes improved. Today, the majority of Italians are able to speak standard Italian, though many Italians still speak their regional language regularly or as their primary day-to-day language, especially at home with family or when communicating with Italians from the same town or region. However, to some Italians, speaking a regional language, especially in a formal setting or outside of one's region, may carry a stigma or negative connotations associated with being lower class, uneducated, boorish, or overly informal.
Is there an answer to this question: What is never associated with being overly informal?

Answer: unanswerable


Problem: Palermo:

The Muslims took control of the Island in 904, after decades of fierce fighting, and the Emirate of Sicily was established. Muslim rule on the island lasted for about 120 years and was marked by cruelty and brutality against the native population, which was reduced into near slavery[clarification needed] and Christian churches across the island were all completely destroyed.[page needed] Palermo (Balarm during Arab rule) displaced Syracuse as the capital city of Sicily. It was said to have then begun to compete with Córdoba and Cairo in terms of importance and splendor. For more than one hundred years Palermo was the capital of a flourishing emirate. The Arabs also introduced many agricultural crops which remain a mainstay of Sicilian cuisine.

What did the Arabs introduce that continues to be relevant to Palermo's culture today?

agricultural crops
