As a result of african american activism in the early 1900s, the 1960s brought the first nomination of an african american for us president. total integration in housing, jobs, and government. new laws protecting voting and other civil rights. a majority of whites backing the efforts of african americans.

The correct answer is: "new laws protecting voting and other civil rights."

The 14th and 15th Amendments to the US Constitution, enacted during the Reconstruction Era, already contained provisions to ensure equality of rights for all US citizens, without discrimination in terms on race. In practice, discrimination continued to be present not only in the society, but also in the legal systems of some states that legitimized practices such as segregation or that enacted laws to set limits to the voting rights of the African American sectors of the population (for example, a minimum income requeriment to be able to vote or literacy tests).

The Voting Rights Act, issued in 1965 is a federal legal instruments that prohibits racial discrimination in voting rights and to enforce the provisions introduced by the 14th and 15th amendments. African-American activisim and, specially the scope of the Civil Rights Movement gave rise to its enactment, together with other pieces of legislation that would protect equally all US citizens, both in theory and practice.

Explanation:

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
