Question: Among predators there is a large degree of specialization. Many predators specialize in hunting only one species of prey. Others are more opportunistic and will kill and eat almost anything (examples: humans, leopards, dogs and alligators). The specialists are usually particularly well suited to capturing their preferred prey. The prey in turn, are often equally suited to escape that predator. This is called an evolutionary arms race and tends to keep the populations of both species in equilibrium. Some predators specialize in certain classes of prey, not just single species. Some will switch to other prey (with varying degrees of success) when the preferred target is extremely scarce, and they may also resort to scavenging or a herbivorous diet if possible.[citation needed]
Try to answer this question if possible: What term describes how predators occasionally switch to a scavenging or herbivorous diet?
Answer: unanswerable
Question: Starting in 1940 (18 months before Pearl Harbor), the nation mobilized, giving high priority to air power. American involvement in World War II in 194041 was limited to providing war material and financial support to Britain, the Soviet Union, and the Republic of China. The U.S. entered officially on 8 December 1941 following the Japanese attack on Pearl Harbor, Hawaii. Japanese forces soon seized American, Dutch, and British possessions across the Pacific and Southeast Asia, except for Australia, which became a main American forward base along with Hawaii.

Question: Claiming the right to name his discovery, Le Verrier quickly proposed the name Neptune for this new planet, though falsely stating that this had been officially approved by the French Bureau des Longitudes. In October, he sought to name the planet Le Verrier, after himself, and he had loyal support in this from the observatory director, Francois Arago. This suggestion met with stiff resistance outside France. French almanacs quickly reintroduced the name Herschel for Uranus, after that planet's discoverer Sir William Herschel, and Leverrier for the new planet.
Try to answer this question if possible: Who claimed the right to name Neptune?
Answer: Le Verrier
Question: After the formal end of Reconstruction, the struggle over power in Southern society continued. Through violence and intimidation against freedmen and their allies, White Democrats regained political power in Tennessee and other states across the South in the late 1870s and 1880s. Over the next decade, the state legislature passed increasingly restrictive laws to control African Americans. In 1889 the General Assembly passed four laws described as electoral reform, with the cumulative effect of essentially disfranchising most African Americans in rural areas and small towns, as well as many poor Whites. Legislation included implementation of a poll tax, timing of registration, and recording requirements. Tens of thousands of taxpaying citizens were without representation for decades into the 20th century. Disfranchising legislation accompanied Jim Crow laws passed in the late 19th century, which imposed segregation in the state. In 1900, African Americans made up nearly 24% of the state's population, and numbered 480,430 citizens who lived mostly in the central and western parts of the state.
Try to answer this question if possible: What is the name for laws dating from the late-19th century which promoted segregation?
Answer:
Jim Crow laws
