Input: Read this: Thomas Edison began serious research into developing a practical incandescent lamp in 1878. Edison filed his first patent application for "Improvement In Electric Lights" on 14 October 1878. After many experiments, first with carbon in the early 1880s and then with platinum and other metals, in the end Edison returned to a carbon filament. The first successful test was on 22 October 1879, and lasted 13.5 hours. Edison continued to improve this design and by 4 November 1879, filed for a US patent for an electric lamp using "a carbon filament or strip coiled and connected ... to platina contact wires." Although the patent described several ways of creating the carbon filament including using "cotton and linen thread, wood splints, papers coiled in various ways," Edison and his team later discovered that a carbonized bamboo filament could last more than 1200 hours. In 1880, the Oregon Railroad and Navigation Company steamer, Columbia, became the first application for Edison's incandescent electric lamps (it was also the first ship to execute use of a dynamo).

QUES: Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.

What can be considered for the special case of systems which are closed to transfers of matter?
What is the answer?
ANS: Energy transfer

QUES: Southampton's police service is provided by Hampshire Constabulary. The main base of the Southampton operation is a new, eight storey purpose-built building which cost 30 million to construct. The building, located on Southern Road, opened in 2011 and is near to Southampton Central railway station. Previously, the central Southampton operation was located within the west wing of the Civic Centre, however the ageing facilities and the plans of constructing a new museum in the old police station and magistrates court necessitated the move. There are additional police stations at Portswood, Banister Park, Bitterne, and Shirley as well as a British Transport Police station at Southampton Central railway station.
Who is responsible for policing Southampton?

ANS: Hampshire Constabulary

The category of Native American applies to the diverse group of people who lived in North America before European settlement. During the U.S. government's westward expansion, Native Americans were displaced from their land which had been their home for centuries. Instead, they were forced onto reservations which were far smaller and less productive. According to Brest, land belonging to Native Americans was reduced from 138 million acres in 1887 to 52 million acres in 1934. In 1990, the poverty rate for Native Americans was more than triple that of the whites and only 9.4% of Native Americans have completed a bachelor's degree as opposed to 25.2% of whites and 12.2% of African Americans.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which groups can be categorized as Non-Native Americans?
Ah, so.. unanswerable

Question: Voiced consonants are seldom actually aspirated. Symbols for voiced consonants followed by , such as b, typically represent consonants with breathy voiced release (see below). In the grammatical tradition of Sanskrit, aspirated consonants are called voiceless aspirated, and breathy-voiced consonants are called voiced aspirated.
Try to answer this question if possible: Voiced aspirated consonants are what type?
Answer: breathy-voiced

Context and question: The majority of the province's population is Han Chinese, who are found scattered throughout the region with the exception of the far western areas. Thus, significant minorities of Tibetan, Yi, Qiang and Nakhi people reside in the western portion that are impacted by inclement weather and natural disasters, environmentally fragile, and impoverished. Sichuan's capital of Chengdu is home to a large community of Tibetans, with 30,000 permanent Tibetan residents and up to 200,000 Tibetan floating population. The Eastern Lipo, included with either the Yi or the Lisu people, as well as the A-Hmao, also are among the ethnic groups of the provinces.
What group makes up a minority of the privinces population?
Answer:
unanswerable
