The east coast Appalachian system, originally forest covered, is relatively low and narrow and is bordered on the southeast and south by an important coastal plain. The Cordilleran system on the western side of the continent is lofty, broad and complicated having two branches, the Rocky Mountain System and the Pacific Mountain System. In between these mountain systems lie the Intermontaine Plateaus. Both the Columbia River and Colorado River rise far inland near the easternmost members of the Cordilleran system, and flow through plateaus and intermontaine basins to the ocean. Heavy forests cover the northwest coast, but elsewhere trees are found only on the higher ranges below the Alpine region. The intermontane valleys, plateaus and basins range from treeless to desert with the most arid region being in the southwest.
Which two major rivers are located in the Cordilleran system?
A: Columbia River and Colorado River

In Australia, nonprofit organisations include trade unions, charitable entities, co-operatives, universities and hospitals, mutual societies, grass-root and support groups, political parties, religious groups, incorporated associations, not-for-profit companies, trusts and more. Furthermore, they operate across a multitude of domains and industries, from health, employment, disability and other human services to local sporting clubs, credit unions and research institutes. A nonprofit organisation in Australia can choose from a number of legal forms depending on the needs and activities of the organisation: co-operative, company limited by guarantee, unincorporated association, incorporated association (by the Associations Incorporation Act 1985) or incorporated association or council (by the Commonwealth Aboriginal Councils and Associations Act 1976). From an academic perspective, social enterprise is for the most part considered a sub-set of the nonprofit sector as typically they too are concerned with a purpose relating to a public good, however these are not bound to adhere to a nonprofit legal structure and many incorporate and operate as for-profit entities.
What can the employment industry in Australia choose from depending on their needs?
A: unanswerable

As of the 2015–16 season, Premier League football has been played in 53 stadiums since the formation of the Premier League in 1992. The Hillsborough disaster in 1989 and the subsequent Taylor Report saw a recommendation that standing terraces should be abolished; as a result all stadiums in the Premier League are all-seater. Since the formation of the Premier League, football grounds in England have seen constant improvements to capacity and facilities, with some clubs moving to new-build stadiums. Nine stadiums that have seen Premier League football have now been demolished. The stadiums for the 2010–11 season show a large disparity in capacity: Old Trafford, the home of Manchester United has a capacity of 75,957 with Bloomfield Road, the home of Blackpool, having a capacity of 16,220. The combined total capacity of the Premier League in the 2010–11 season is 770,477 with an average capacity of 38,523.
What was the result of their recommendation?
A: as a result all stadiums in the Premier League are all-seater

As aircraft started to be used against ground targets on the battlefield, the AA guns could not be traversed quickly enough at close targets and, being relatively few, were not always in the right place (and were often unpopular with other troops), so changed positions frequently. Soon the forces were adding various machine-gun based weapons mounted on poles. These short-range weapons proved more deadly, and the "Red Baron" is believed to have been shot down by an anti-aircraft Vickers machine gun. When the war ended, it was clear that the increasing capabilities of aircraft would require better means of acquiring targets and aiming at them. Nevertheless, a pattern had been set: anti-aircraft weapons would be based around heavy weapons attacking high-altitude targets and lighter weapons for use when they came to lower altitudes.
What made acquiring targets and aiming more required?
A:
increasing capabilities of aircraft
