Correct answer: a. The Sussex Pledge
Explanation/details:
- Public outrage in the US against the Germans swept the nation following the sinking of the British ocean liner, <em>Lusitania,</em> which had happened in May, 1915. When a German U-boat (submarine) sank the <em>Lusitania</em>, over 1,000 persons were killed, including more than 100 Americans. The passenger liner was targeted by the Germans because they suspected weapons were being shipped to Britain in the cargo hold of the ship. After the <em>Sussex, </em>a French passenger ferry, was sunk in 1916, the US demanded and got a promise from Germany to stop their unrestricted submarine attacks. Germany managed to stave off American entry into the war at that time by the Sussex Pledge. But two years, later, beginning February 1, 1917, the Germans resumed such attacks. This poised America to go to war.
The volume of miners and industries using copper in the 20th century presented an exponential growth. Mining tends to extract the highest grade resources first, once they are the most profitable. With the intense activity achieved during the last century, the higher grade non renewable sources were quickly depleted, forcing the industry to start exploring lower grades sources to satisfy the demand.
It is also noteworthy that mining copper of higher quality causes more damage to the environment, having its protocols and restrictions consequently addressed by the legislation. Therefore the costs of mining 5% copper might be outweighed by a higher margin of profit from 0.5% copper which also is less damaging to the environment.
They believed that the states would give too much power to the government.
