The two reasons:
- Britain intercepted the Zimmerman Telegram
- Germany resumed unrestricted submarine warfare
Context/detail:
Public outrage in the US against the Germans swept the nation following the sinking of the British ocean liner, <em>Lusitania</em> -- but that happened before 1917. When a German U-boat (submarine) sank the Lusitania in May, 1915, 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.
Germany managed to stave off American entry into the war at the time by pledging to stop submarine attacks. But a couple years later they resumed such attacks, and there was also an intercepted telegram (the "Zimmerman Telegram") that showed Germany was trying to secure Mexico as an ally against the United States.
In 1917, the US declared war on Germany in response.
I'd say pollution or disease.
A <u>D. market basket</u> contains thousands of specific items that represent what average urban households purchase month after month.
In economy, this economic market basket's items refers to goods and services purchased. It is used to track price changes over time and determine inflation levels, to help measure the cost of living of a giving group of people and help predict consumer purchase trends.
Some examples of the categories of items found there are food, beverages, housing, apparel, transportation, medical care, and education.
The Puget Sound Basin is located in the Pacific Northwest, as part of an inlet of the Pacific Ocean and the Salish Sea. This means that the area comprises the northwestern coast of the U.S. state of Washington.
The Puget Sound Basin is particularly important to the economy of the state of Washington because of two main resources: water and animal species. The Puget Sound Basin contains surface and ground-water resources that play an important economic and ecological role. The resource is economically important because it provides water for an expanding population, hydroelectric power, recreational opportunities and an ecosystem that sustains fishery.
While fishery is also a major economic contribution of this area, some factors have made this business less sustainable. These include the loss of aquatic habitat, unsustainable agricultural practices in the region, washoff of metals, pesticides and petroleum products and nutrient enrichment of lakes and embayments. This means that populations of the species in the region have decreased in recent years.
