QUES: Racial discrimination continued to be enacted in new laws in the 20th century, for instance the one-drop rule was enacted in Virginia's 1924 Racial Integrity Law and in other southern states, in part influenced by the popularity of eugenics and ideas of racial purity. People buried fading memories that many whites had multiracial ancestry. Many families were multiracial. Similar laws had been proposed but not passed in the late nineteenth century in South Carolina and Virginia, for instance. After regaining political power in Southern states by disenfranchising blacks, white Democrats passed laws to impose Jim Crow and racial segregation to restore white supremacy. They maintained these until forced to change in the 1960s and after by enforcement of federal legislation authorizing oversight of practices to protect the constitutional rights of African Americans and other minority citizens.

In what years did democrats pass laws to impose Jim Crow?
What is the answer?
ANS: unanswerable
QUES: Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal becomes brittle again and can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has relatively low melting (419.5 °C) and boiling points (907 °C). Its melting point is the lowest of all the transition metals aside from mercury and cadmium.

Is iron more dense than zinc?
