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!

The answer for your question this the first one witch is (A)
<u>Answer</u>: e) Volcanic activity in the region leaves behind valuable minerals.
<u />
<u>Explanation</u>: Volcanic activity has played an important role in the creation of the Cascade Mountains as they were originally created through the subduction of two continental plates.
It is well known that gold deposists are often found through volcanic systems. Water heated by volcanoes will become very acid and thus dissolve surrounding rocks. This water that will contain gold and other metals will then follow fractures through the bedrock towards the surface. In time, these will turn into gold veins or lodes.
