QUES: In 1976 John Goldsmith introduced autosegmental phonology. Phonological phenomena are no longer seen as operating on one linear sequence of segments, called phonemes or feature combinations, but rather as involving some parallel sequences of features which reside on multiple tiers. Autosegmental phonology later evolved into feature geometry, which became the standard theory of representation for theories of the organization of phonology as different as lexical phonology and optimality theory.

QUES: In parliamentary systems, governments are generally required to have the confidence of the lower house of parliament (though a small minority of parliaments, by giving a right to block supply to upper houses, in effect make the cabinet responsible to both houses, though in reality upper houses, even when they have the power, rarely exercise it). Where they lose a vote of confidence, have a motion of no confidence passed against them, or where they lose supply, most constitutional systems require either:

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.

What had popularity in the early 20th century that caused rising racial discrimination?
What is the answer?
