Problem: Hunting:

Hunting is primarily regulated by state law; additional regulations are imposed through United States environmental law in the case of migratory birds and endangered species. Regulations vary widely from state to state and govern the areas, time periods, techniques and methods by which specific game animals may be hunted. Some states make a distinction between protected species and unprotected species (often vermin or varmints for which there are no hunting regulations). Hunters of protected species require a hunting license in all states, for which completion of a hunting safety course is sometimes a prerequisite.

What hunters require a hunting license in all states?

A: Hunters of protected species

Problem: Lossy audio compression is used in a wide range of applications. In addition to the direct applications (mp3 players or computers), digitally compressed audio streams are used in most video DVDs, digital television, streaming media on the internet, satellite and cable radio, and increasingly in terrestrial radio broadcasts. Lossy compression typically achieves far greater compression than lossless compression (data of 5 percent to 20 percent of the original stream, rather than 50 percent to 60 percent), by discarding less-critical data.
What gets between 5 percent and 50 percent compression?

The Trans-Alaska Pipeline can transport and pump up to 2.1 million barrels (330,000 m3) of crude oil per day, more than any other crude oil pipeline in the United States. Additionally, substantial coal deposits are found in Alaska's bituminous, sub-bituminous, and lignite coal basins. The United States Geological Survey estimates that there are 85.4 trillion cubic feet (2,420 km3) of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. Alaska also offers some of the highest hydroelectric power potential in the country from its numerous rivers. Large swaths of the Alaskan coastline offer wind and geothermal energy potential as well.
How much recoverable gas is still undiscovered in Alaska, according to the US Geological Survey?
A: 85.4 trillion cubic feet

Context and question: Several influential people of the time, including Bell, viewed deafness as something that should be eradicated, and also believed that with resources and effort they could teach the deaf to speak and avoid the use of sign language, thus enabling their integration within the wider society from which many were often being excluded. In several schools, children were mistreated, for example by having their hands tied behind their backs so they could not communicate by signingthe only language they knewin an attempt to force them to attempt oral communication. Owing to his efforts to suppress the teaching of sign language, Bell is often viewed negatively by those embracing Deaf culture.
Bell's goal was to instruct the deaf to speak and not use what?
Answer: sign language

Question: Bermuda's culture is a mixture of the various sources of its population: Native American, Spanish-Caribbean, English, Irish, and Scots cultures were evident in the 17th century, and became part of the dominant British culture. English is the primary and official language. Due to 160 years of immigration from Portuguese Atlantic islands (primarily the Azores, though also from Madeira and the Cape Verde Islands), a portion of the population also speaks Portuguese. There are strong British influences, together with Afro-Caribbean ones.
Is there an answer to this question: What are the greatest influences to Bermudian culture?

Answer: British influences, together with Afro-Caribbean

The inhabitants of the British Isles have been drinking ale since the Bronze Age, but it was with the arrival of the Roman Empire in its shores in the 1st Century, and the construction of the Roman road networks that the first inns, called tabernae, in which travellers could obtain refreshment began to appear. After the departure of Roman authority in the 5th Century and the fall of the Romano-British kingdoms, the Anglo-Saxons established alehouses that grew out of domestic dwellings, the Anglo-Saxon alewife would put a green bush up on a pole to let people know her brew was ready. These alehouses quickly evolved into meeting houses for the folk to socially congregate, gossip and arrange mutual help within their communities. Herein lies the origin of the modern public house, or "Pub" as it is colloquially called in England. They rapidly spread across the Kingdom, becoming so commonplace that in 965 King Edgar decreed that there should be no more than one alehouse per village.
In what century did the Romans arrive in Britain?
A:
the 1st Century
