Answer;
-Prevent Propeller Strikes
Explanation;
Propeller guards, or prop guards as they are commonly called, are devices that mount on the lower unit of an outboard motor.These propeller guards surround the propeller and protect it from damage when encountering a rock or other underwater obstacle.
They are manufactured from mild steel rod or heavy plastic, the guards allow water to flow freely through them, so the propeller is able to get a good bite on the water. Grass and weeds are also kept clear of the propeller, and damage to propellers, bearings and seals is greatly reduced through the use of guards.
Answer:
Post-1945 immigration to the United States differed fairly dramatically from America’s earlier 20th- and 19th-century immigration patterns, most notably in the dramatic rise in numbers of immigrants from Asia. Beginning in the late 19th century, the U.S. government took steps to bar immigration from Asia. The establishment of the national origins quota system in the 1924 Immigration Act narrowed the entryway for eastern and central Europeans, making western Europe the dominant source of immigrants. These policies shaped the racial and ethnic profile of the American population before 1945. Signs of change began to occur during and after World War II. The recruitment of temporary agricultural workers from Mexico led to an influx of Mexicans, and the repeal of Asian exclusion laws opened the door for Asian immigrants. Responding to complex international politics during the Cold War, the United States also formulated a series of refugee policies, admitting refugees from Europe, the western hemisphere, and later Southeast Asia. The movement of people to the United States increased drastically after 1965, when immigration reform ended the national origins quota system. The intricate and intriguing history of U.S. immigration after 1945 thus demonstrates how the United States related to a fast-changing world, its less restrictive immigration policies increasing the fluidity of the American population, with a substantial impact on American identity and domestic policy.
