Answer:
The machine-gun was one of the deadliest weapons of the Western Front, causing thousands of casualties. It was a relatively new weapon at the start of the war, but British and German forces soon realised its potential as a killing machine, especially when fired from a fixed defensive position.
The Vickers machine-gun (above) was famed for its reliability and could fire over 600 rounds per minute and had a range of 4,500 yards. With proper handling, it could sustain a rate of fire for hours. This was providing that a necessary supply of belted ammunition, spare barrels and cooling water was available. When there was no water to hand, soldiers would urinate in the water jacket to keep the gun cool!
Explanation:
Economic development is able to continue in the absence of the resources that first drove it because:
- Countries can trade to get the resources
- Economic development allows for diversification
When a nation is unable to access the resources that made it quite successful, it can resort to buying that resource and then improving on it.
For instance, the U.K. used to produce sufficient coal but now import more than they produce.
Another way a nation can continue developing is diversification. The income gained from the resource that has now finished, will enable a nation to go into other economic activities which will continue their development.
For example, China used to export only agricultural goods but diversified into industrial.
In conclusion, a country can keep developing if their primary resource is finished thanks to trade and diversification.
