Restrict the ability of African Americans to obtain voting rights.
The black community had less access to education than whites even after slavery was ended; thus their literacy rates were lower. They also experienced much poverty because of prejudice against them in the economic system of the country, so poll taxes could keep them from going to the polls to vote. The "grandfather clauses" were exemptions granted by some states to those whose forefathers ("grandfathers") had full voting rights prior to the Civil War, so if there were poor or illiterate whites, they could vote freely while blacks (whose ancestors had been slaves) were subjected to the laws restricting their voting ability.
These sorts of restrictions against black voters prompted much of the activism of the civil rights movement that began in the middle of the 20th century.
The movable type was invented around AD 1040 in China during the Song Dinasty. It was a way of printing in which movable elements were used to reproduce documents, usually on paper. It had a great influence on learning if we consider that paper books could be printed and spread to different places
Not at all because were too distracted by all these campaigns which only one matters and that’s the “All lives Matter” we need to be a unit.:)

North America has four major deserts: Great Basin, Mohave, Chihuahuan and Sonoran. All but the Sonoran Desert have cold winters. Freezing temperatures are even more limiting to plant life than is aridity, so colder deserts are poorer in both species and life forms, especially succulents.
The four North American deserts
The Great Basin Desert (plate 10) is both the highest-elevation and northernmost of the four and has very cold winters. The seasonal distribution of precipitation varies with latitude, but temperatures limit the growing season to the summer. Vegetation is dominated by a few species of low, small-leafed shrubs; there are almost no trees or succulents and not many annuals. The indicator plant (the most common or conspicuous one used to identify an area) is big sagebrush (Artemisia tridentata), which often grows in nearly pure stands over huge vistas. (Such cold shrub/deserts in the "Old World" are called steppes.)
The Mohave Desert (plate 11) is characterized largely by its winter rainy season. Hard freezes are common but not as severe as in the Great Basin Desert. The perennial vegetation is composed mostly of low shrubs; annuals carpet the ground in wet years. There are many species of these two life forms, but few succulents and trees grow there. The only common tree species is the characteristic joshua tree (Yucca brevifolia), an arborescent (treelike) yucca that forms extensive woodlands above 3000 feet (900 m) elevation.
Though the Chihuahuan Desert (plate 12) is the southernmost, it lies at a fairly high elevation and is not protected by any barrier from arctic air masses, so hard winter freezes are common. Its vegetation consists of many species of low shrubs, leaf succulents, and small cacti. Trees are rare. Rainfall is predominantly in the summer, but in the northern end there is occasionally enough winter rain to support massive blooms of spring annuals. The Chihuahuan Desert is unexpectedly rich in species despite the winter cold.
